"Ye are complete in Him." -- Paul.
"Whatever amount of power an organism expends in any shape is the correlate and equivalent of a power that was taken into it from without." -- Herbert Spencer.
STUDENTS of Biography will observe that in all well written Lives attention is concentrated for the first few chapters upon two points. We are first introduced to the family to which the subject of memoir belonged. The grandparents, or even the more remote ancestors, are briefly sketched and their chief characteristics brought prominently into view. Then the parents themselves are photographed in detail. Their appearance and physique, their character, their disposition, their mental qualities, are set before us in a critical analysis. And finally we are asked to observe how much the father and the mother respectively have transmitted of their peculiar nature to their offspring. How faithfully the ancestral lines have met in the latest product, how mysteriously the joint characteristics of body and mind have blended, and how unexpected yet how entirely natural a recombination is the result -- these points are elaborated with cumulative effect until we realize at last how little we are dealing with an independent unit, how much with a survival and reorganization of what seemed buried in the grave.
In the second place, we are invited to consider more external influences -- schools and schoolmasters, neighbours, home, pecuniary circumstances, scenery, and, by-and-by, the religious and political atmosphere of the time. These also we are assured have played their part in making the individual what he is. We can estimate these early influences in any particular case with but small imagination if we fail to see how powerfully they also have moulded mind and character, and in what subtle ways they have determined the course of the future life.
This twofold relation of the individual, first, to his parents, and second, to his circumstances, is not peculiar to human beings. These two factors are responsible for making all living organisms what they are. When a naturalist attempts to unfold the life-history of any animal, he proceeds precisely on these same lines. Biography is really a branch of Natural History; and the biographer, who discusses his hero as the resultant of these two tendencies, follows the scientific method as rigidly as Mr. Darwin in studying "Animals and Plants under Domestication."
Mr. Darwin, following Weismann, long ago pointed out that there are two main factors in all Evolution -- the nature of the organism and the nature of the conditions. We have chosen our illustration from the highest or human species in order to define the meaning of these factors in the clearest way; but it must be remembered that the development of man under these directive influences is essentially the same as that of any other organism in the hands of Nature. We are dealing therefore with universal Law. It will still further serve to complete the conception of the general principle if we now substitute for the casual phrases by which the factors have been described the more accurate terminology of Science. Thus what Biography describes as parental influences, Biology would speak of as Heredity; and all that is involved in the second factor -- the action of external circumstances and surroundings -- the naturalist would include under the single term Environment. These two, Heredity and Environment, are the master-influences of the organic world. These have made all of us what we are. These forces are still ceaselessly playing upon all our lives. And he who truly understands these influences; he who has decided how much to allow to each: he who can regulate new forces as they arise, or adjust them to the old, so directing them as at one moment to make them co-operate, at another to counteract one another, understands the rationale of personal development. To seize continuously the opportunity of more and more perfect adjustment to better and higher conditions, to balance some inward evil with some purer influence acting from without, in a word to make our Environment at the same time that it is making us, -- these are the secrets of a well-ordered and successful life.
In the spiritual world, also, the subtle influences which form and transform the soul are Heredity and Environment. And here especially where all is invisible, where much that we feel to be real is yet so ill-defined, it becomes of vital practical moment to clarify the atmosphere as far as possible with conceptions borrowed from the natural life. Few thinkers are less understood than the conditions of the spiritual life. The distressing incompetence of which most of us are conscious in trying to work out our spiritual experience is due perhaps less to the diseased will which we commonly blame for it than to imperfect knowledge of the right conditions. It does not occur to us how natural the spiritual is. We still strive for some strange transcendent thing; we seek to promote life by methods as unnatural as they prove unsuccessful; and only the utter incomprehensibility of the whole region prevents us seeing fully -- what we already half suspect -- how completely we are missing the road. Living in the spiritual world, nevertheless, is just as simple as living in the natural world; and it is the same kind of simplicity. It is the same kind of simplicity for it is the same kind of world -- there are not two kinds of worlds. The conditions of life in the one are the conditions of life in the other. And till these conditions are sensibly grasped, as the conditions of all life, it is impossible that the personal effort after the highest life should be other than a blind struggle carried on in fruitless sorrow and humiliation.
Of these two universal factors, Heredity and Environment, it is unnecessary to balance the relative importance here. The main influence, unquestionably, must be assigned to the former. In practice, however, and for an obvious reason, we are chiefly concerned with the latter. What Heredity has to do for us is determined outside ourselves. No man can select his own parents. But every man to some extent can choose his own Environment. His relation to it, however largely determined by Heredity in the first instance, is always open to alteration. And so great is his control over Environment and so radical its influence over him, that he can so direct it as either to undo modify, perpetuate or intensify the earlier hereditary influences within certain limits. But the aspects of Environment which we have now to consider do not involve us in questions of such complexity. In what high and mystical sense, also, Heredity applies to the spiritual organism we need not just now inquire. In the simpler relations of the more external factor we shall find a large and fruitful field for study.
The Influence of Environment may be investigated in two main aspects. First, one might discuss the modern and very interesting question as to the power of Environment to induce what is known to recent science as Variation. A change in the surroundings of any animal, it is now well-known, can so react upon it as to cause it to change. By the attempt, conscious or unconscious, to adjust itself to the new conditions, a true physiological change is gradually wrought within the organism. Hunter, for example, in a classical experiment, so changed the Environment of a sea-gull by keeping it in captivity that it could only secure a grain diet. The effect was to modify the stomach of the bird, normally adapted to a fish diet, until in time it came to resemble in structure the gizzard of an ordinary grain-feeder such as the pigeon. Holmgren again reversed this experiment by feeding pigeons for a lengthened period on a meat-diet, with the result that the gizzard became transformed into the carnivorous stomach. Mr. Alfred Russel Wallace mentions the case of a Brazilian parrot which changes its colour from green to red or yellow when fed on the fat of certain fishes. Not only changes of food, however, but changes of climate and of temperature, changes in surrounding organisms, in the case of marine animals even changes of pressure, of ocean currents, of light, and of many other circumstances, are known to exert a powerful modifying influence upon living organisms. These relations are still being worked out in many directions, but the influence of Environment as a prime factor in Variation is now a recognised doctrine of science. 
Even the popular mind has been struck with the curious adaptation of nearly all animals to their habitat, for example in the matter of colour. The sandy hue of the sole and flounder, the white of the polar bear with its suggestion of Arctic snows, the stripes of the Bengal tiger -- as if the actual reeds of its native jungle had nature-printed themselves on its hide; -- these, and a hundred others which will occur to every one, are marked instances of adaptation to Environment induced, by Natural Selection or otherwise, for the purpose, obviously in these cases at least, of protection.
To continue the investigation of the modifying action of Environment into the moral and spiritual spheres, would be to open a fascinating and suggestive inquiry. One might show how the moral man is acted upon and changed continuously by the influences, secret and open, of his surroundings, by the tone of society, by the company he keeps, by his occupation, by the books he reads, by Nature, by all, in short, that constitutes the habitual atmosphere of his thoughts and the little world of his daily choice. Or one might go deeper still and prove how the spiritual life also is modified from outside sources -- its health or disease, its growth or decay, all its changes for better or for worse being determined by the varying and successive circumstances in which the religious habits are cultivated. But we must rather transfer our attention to a second aspect of environment, not perhaps so fascinating but yet more important.
So much of the modern discussion of Environment revolves round the mere question of Variation that one is apt to overlook a previous question. Environment as a factor in life is not exhausted when we have realized its modifying influence. Its significance is scarcely touched. The great function of Environment is not to modify but to sustain. In sustaining life, it is true, it modifies. But the latter influence is incidental, the former essential. Our Environment is that in which we live and move and have our being. Without it we should neither live nor move nor have any being. In the organism lies the principle of life; in the Environment are the conditions of life. Without the fulfilment of these conditions, which are wholly supplied by Environment, there can be no life. An organism in itself is but a part; Nature is its complement. Alone, cut off from its surroundings, it is not. Alone, cut off from my surroundings, I am not -- physically I am not. I am, only as I am sustained. I continue only as I receive. My Environment may modify me, but it has first to keep me. And all the time its secret transforming power is indirectly moulding body and mind it is directly active in the more open task of ministering to my myriad wants and from hour to hour sustaining life itself.
To understand the sustaining influence of Environment in the animal world, one has only to recall what the biologist terms the extrinsic or subsidiary conditions of vitality. Every living thing normally requires for its development an Environment containing air, light, heat, and water. In addition to these, if vitality is to be prolonged for any length of time, and if it is to be accompanied with growth and the expenditure of energy, there must be a constant supply of food. When we simply remember how indispensable food is to growth and work, and when we further bear in mind that the food-supply is solely contributed by the Environment, we shall realize at once the meaning and the truth of the proposition that without Environment there can be no life. Seventy per cent. at least of the human body is made of pure water, the rest of gases and earths. These have all come from Environment. Through the secret pores of the skin two pounds of water are exhaled daily from every healthy adult. The supply is kept up by Environment. The Environment is really an unappropriated part of ourselves. Definite portions are continuously abstracted from it and added to the organism. And so long as the organism continues to grow, act, think, speak, work, or perform any other function demanding a supply of energy, there is a constant, simultaneous, and proportionate drain upon its surroundings.
This is a truth in the physical, and therefore in the spiritual, world of so great importance that we shall not mis-spend time if we follow it, for further confirmation, into another department of nature. Its significance in Biology is self-evident; let us appeal to Chemistry.
When a piece of coal is thrown on the fire, we say that it will radiate into the room a certain quantity of heat. This heat, in the popular conception, is supposed to reside in the coal and to be set free during the process of combustion. In reality, however, the heat energy is only in part contained in the coal. It is contained just as truly in the coal's Environment -- that is to say, in the oxygen of the air. The atoms of carbon which compose the coal have a powerful affinity for the oxygen of the air. Whenever they are made to approach within a certain distance of one another, by the initial application of heat, they rush together with inconceivable velocity. The heat which appears at this moment, comes neither from the carbon alone, nor from the oxygen alone. These two substances are really inconsumable, and continue to exist, after they meet in a combined form, as carbonic acid gas. The heat is due to the energy developed by the chemical embrace, the precipitate rushing together of the molecules of carbon and the molecules of oxygen. It comes, therefore, partly from the coal and partly from the Environment. Coal alone never could produce heat, neither alone could Environment. The two are mutually dependent. And although in nearly all the arts we credit everything to the substance which we can weigh and handle, it is certain that in most cases the larger debt is due to an invisible Environment.
This is one of those great commonplaces which slip out of general reckoning by reason of their very largeness and simplicity. How profound, nevertheless, are the issues which hang on this elementary truth, we shall discover immediately. Nothing in this age is more needed in every department of knowledge than the rejuvenescence of the commonplace. In the spiritual world especially, he will be wise who courts acquaintance with the most ordinary and transparent facts of Nature; and in laying the foundations for a religious life he will make no unworthy beginning who carries with him an impressive sense of so obvious a truth as that without Environment there can be no life.
For what does this amount to in the spiritual world? Is it not merely the scientific re-statement of the reiterated aphorism of Christ, "Without Me ye can do nothing"? There is in the spiritual organism a principle of life; but that is not self-existent. It requires a second factor, a something in which to live and move and have its being, an Environment. Without this it cannot live or move or have any being. Without Environment the soul is as the carbon without the oxygen, as the fish without the water, as the animal frame without the extrinsic conditions of vitality.
And what is the spiritual Environment? It is God. Without this, therefore, there is no life, no thought, no energy, nothing -- "without Me ye can do nothing."
The cardinal error in the religious life is to attempt to live without an Environment. Spiritual experience occupies itself, not too much, but too exclusively, with one factor -- the soul. We delight in dissecting this much tortured faculty, from time to time, in search of a certain something which we call our faith -- forgetting that faith is but an attitude, an empty hand for grasping an environing Presence. And when we feel the need of a power by which to overcome the world, how often do we not seek to generate it within ourselves by some forced process, some fresh girding of the will, some strained activity which only leaves the soul in further exhaustion? To examine ourselves is good; but useless unless we also examine Environment. To bewail our weakness is right, but not remedial. The cause must be investigated as well as the result. And yet, because we never see the other half of the problem, our failures even fail to instruct us. After each new collapse we begin our life anew, but on the old conditions; and the attempt ends as usual in the repetition -- in the circumstances the inevitable repetition -- of the old disaster. Not that at times we do not obtain glimpses of the true state of the case. After seasons of much discouragement, with the sore sense upon us of our abject feebleness, we do confer with ourselves, insisting for the thousandth time, "My soul, wait thou only upon God." But, the lesson is soon forgotten. The strength supplied we speedily credit to our own achievement; and even the temporary success is mistaken for a symptom of improved inward vitality. Once more we become self-existent. Once more we go on living without an Environment. And once more, after days of wasting without repairing, of spending without replenishing, we begin to perish with hunger, only returning to God again, as a last resort, when we have reached starvation point.
Now why do we do this? Why do we seek to breathe without an atmosphere, to drink without a well? Why this unscientific attempt to sustain life for weeks at a time without an Environment? It is because we have never truly seen the necessity for an Environment. We have not been working with a principle. We are told to "wait only upon God," but we do not know why. It has never been as clear to us that without God the soul will die as that without food the body will perish. In short, we have never comprehended the doctrine of the Persistence of Force. Instead of being content to transform energy we have tried to create it.
The Law of Nature here is as clear as Science can make it. In the words of Mr. Herbert Spencer, "It is a corollary from that primordial truth which, as we have seen, underlies all other truths, that whatever amount of power an organism expends in any shape is the correlate and equivalent of a power that was taken into it from without."  We are dealing here with a simple question of dynamics. Whatever energy the soul expends must first be "taken into it from without." We are not Creators, but creatures; God is our refuge and strength. Communion with God, therefore, is a scientific necessity; and nothing will more help the defeated spirit which is struggling in the wreck of its religious life than a common-sense hold of this plain biological principle that without Environment he can do nothing. What he wants is not an occasional view, but a principle -- a basal principle like this, broad as the universe, solid as nature. In the natural world we act upon this law unconsciously. We absorb heat, breathe air, draw on Environment all but automatically for meat and drink, for the nourishment of the senses, for mental stimulus, for all that, penetrating us from without, can prolong, enrich, and elevate life. But in the spiritual world we have all this to learn. We are new creatures, and even the bare living has to be acquired.
Now the great point in learning to live is to live naturally. As closely as possible we must follow the broad, clear lines of the natural life. And there are three things especially which it is necessary for us to keep continually in view. The first is that the organism contains within itself only one-half of what is essential to life; the second is that the other half is contained in the Environment; the third, that the condition of receptivity is simple union between the organism and the Environment.
Translated into the language of religion these propositions yield, and place on a scientific basis, truths of immense practical interest. To say, first, that the organism contains within itself only one-half of what is essential to life, is to repeat the evangelical confession, so worn and yet so true to universal experience, of the utter helplessness of man. Who has not come to the conclusion that he is but a part, a fraction of some larger whole? Who does not miss at every turn of his life an absent God? That man is but a part, he knows, for there is room in him for more. That God is the other part, he feels, because at times He satisfies his need. Who does not tremble often under that sicklier symptom of his incompleteness, his want of spiritual energy, his helplessness with sin? But now he understands both -- the void in his life, the powerlessness of his will. He understands that, like all other energy, spiritual power is contained in Environment. He finds here at last the true root of all human frailty, emptiness, nothingness, sin. This is why "without Me ye can do nothing." Powerlessness is the normal state not only of this but of every organism -- of every organism apart from its Environment.
The entire dependence of the soul upon God is not an exceptional mystery, nor is man's helplessness an arbitrary and unprecedented phenomenon. It is the law of all Nature. The spiritual man is not taxed beyond the natural. He is not purposely handicapped by singular limitations or unusual incapacities. God has not designedly made the religious Life as hard as possible. The arrangements for the spiritual life are the same as for the natural life. When in their hours of unbelief men challenge their Creator for placing the obstacle of human frailty in the way of their highest development, their protest is against the order of nature. They object to the sun for being the source of energy and not the engine, to the carbonic acid being in the air and not in the plant. They would equip each organism with a personal atmosphere, each brain with a private store of energy; they would grow corn in the interior of the body, and make bread by a special apparatus in the digestive organs. They must, in short, have the creature transformed into a Creator. The organism must either depend on his environment, or be self-sufficient. But who will not rather approve the arrangement by which man in his creatural life may have unbroken access to an Infinite Power? What soul will seek to remain self-luminous when it knows that "The Lord God is a Sun"? Who will not willingly exchange his shallow vessel for Christ's well of living water? Even if the organism, launched into being like a ship putting out to sea, possessed a full equipment, its little store must soon come to an end. But in contact with a large and bounteous Environment its supply is limitless. In every direction its resources are infinite.
There is a modern school which protests against the doctrine of man's inability as the heartless fiction of a past theology. While some forms of that dogma, to any one who knows man, are incapable of defence, there are others which, to any one who knows Nature, are incapable of denial. Those who oppose it, in their jealousy for humanity, credit the organism with the properties of Environment. All true theology, on the other hand, has remained loyal to at least the root-idea in this truth. The New Testament is nowhere more impressive than where it insists on the fact of man's dependence. In its view the first step in religion is for man to feel his helplessness. Christ's first beatitude is to the poor in spirit. The condition of entrance into the spiritual kingdom is to possess the child-spirit -- that state of mind combining at once the profoundest helplessness with the most artless feeling of dependence. Substantially the same idea underlies the countless passages in which Christ affirms that He has not come to call the righteous, but sinners to repentance. And in that farewell discourse into which the Great Teacher poured the most burning convictions of His life, He gives to this doctrine an ever increasing emphasis. No words could be more solemn or arresting than the sentence in the last great allegory devoted to this theme, "As the branch cannot bear fruit of itself except it abide in the vine, no more can ye except ye abide in Me." The word here, it will be observed again, is cannot. It is the imperative of natural law. Fruit-bearing without Christ is not an improbability, but an impossibility. As well expect the natural fruit to flourish without air and heat, without soil and sunshine. How thoroughly also Paul grasped this truth is apparent from a hundred pregnant passages in which he echoes his Master's teaching. To him life was hid with Christ in God. And that he embraced this not as a theory but as an experimental truth we gather from his constant confession, "When I am weak, then am I strong."
This leads by a natural transition to the second of the three points we are seeking to illustrate. We have seen that the organism contains within itself only one half of what is essential to life. We have next to observe, as the complement of this, how the second half is contained in the Environment.
One result of the due apprehension of our personal helplessness will be that we shall no longer waste our time over the impossible task of manufacturing energy for ourselves. Our science will bring to an abrupt end the long series of severe experiments in which we have indulged in the hope of finding a perpetual motion. And having decided upon this once for all, our first step in seeking a more satisfactory state of things must be to find a new source of energy. Following Nature, only one course is open to us. We must refer to Environment. The natural life owes all to Environment, so must the spiritual. Now the Environment of the spiritual life is God. As Nature therefore forms the complement of the natural life, God is the complement of the spiritual.
The proof of this? That Nature is not more natural to my body than God is to my soul. Every animal and plant has its own Environment. And the further one inquires into the relations of the one to the other, the more one sees the marvellous intricacy and beauty of the adjustments. These wonderful adaptations of each organism to its surroundings -- of the fish to the water, of the eagle to the air, of the insect to the forest-bed; and of each part of every organism -- the fish's swim-bladder, the eagle's eye, the insect's breathing tubes -- which the old argument from design brought home to us with such enthusiasm, inspire us still with a sense of the boundless resource and skill of Nature in perfecting her arrangements for each single life. Down to the last detail the world is made for what is in it; and by whatever process things are as they are, all organisms find in surrounding Nature the ample complement of themselves. Man, too, finds in his Environment provision for all capacities, scope for the exercise of every faculty, room for the indulgence of each appetite, a just supply for every want. So the spiritual man at the apex of the pyramid of life finds in the vaster range of his Environment a provision, as much higher, it is true, as he is higher, but as delicately adjusted to his varying needs. And all this is supplied to him just as the lower organisms are ministered to by the lower environment, in the same simple ways, in the same constant sequence, as appropriately and as lavishly. We fail to praise the ceaseless ministry of the great inanimate world around us only because its kindness is unobtrusive. Nature is always noiseless. All her greatest gifts are given in secret. And we forget how truly every good and perfect gift comes from without, and from above, because no pause in her changeless beneficence teaches us the sad lessons of deprivation.
It is not a strange thing, then, for the soul to find its life in God. This is its native air. God as the Environment of the soul has been from the remotest age the doctrine of all the deepest thinkers in religion. How profoundly Hebrew poetry is saturated with this high thought will appear when we try to conceive of it with this left out. True poetry is only science in another form. And long before it was possible for religion to give scientific expression to its greatest truths, men of insight uttered themselves in psalms which could not have been truer to Nature had the most modern light controlled the inspiration. "As the hart panteth after the water-brooks, so panteth my soul after Thee, O God." What fine sense of the analogy of the natural and the spiritual does not underlie these words. As the hart after its Environment, so man after his; as the water-brooks are fitly designed to meet the natural wants, so fitly does God implement the spiritual need of man. It will be noticed that in the Hebrew poets the longing for God never strikes one as morbid, or unnatural to the men who uttered it. It is as natural to them to long for God as for the swallow to seek her nest. Throughout all their images no suspicion rises within us that they are exaggerating. We feel how truly they are reading themselves, their deepest selves. No false note occurs in all their aspiration. There is no weariness even in their ceaseless sighing except the lover's weariness for the absent -- if they would fly away, it is only to be at rest. Men who have no soul can only wonder at this. Men who have a soul, but with little faith, can only envy it. How joyous a thing it was to the Hebrews to seek their God! How artlessly they call upon Him to entertain them in His pavilion, to cover them with His feathers, to hide them in His secret place, to hold them in the hollow of His hand or stretch around them the everlasting arms! These men were true children of Nature. As the humming-bird among its own palm-trees, as the ephemera in the sunshine of a summer evening, so they lived their joyous lives. And even the full share of the sadder experiences of life which came to all of them but drove them the further into the Secret Place, and led them with more consecration to make, as they expressed it, "the Lord their portion." All that has been said since from Marcus Aurelius to Swedenborg, from Augustine to Schleiermacher of a besetting God as the final complement of humanity is but a repetition of the Hebrew poets's faith. And even the New Testament has nothing higher to offer man than this. The psalmist's "God is our refuge and strength" is only the earlier form, less defined, less practicable, but not less noble, of Christ's "Come unto Me, and I will give you rest."
There is a brief phrase of Paul's which defines the relation with almost scientific accuracy, -- "Ye are complete in Him." In this is summed up the whole of the Bible anthropology -- the completeness of man in God, his incompleteness apart from God.
If it be asked, In what is man incomplete, or, In what does God complete him? the question is a wide one. But it may serve to show at least the direction in which the Divine Environment forms the complement of human life if we ask ourselves once more what it is in life that needs complementing. And to this question we receive the significant answer that it is in the higher departments alone, or mainly, that the incompleteness of our life appears. The lower departments of Nature are already complete enough. The world itself is about as good a world as might be. It has been long in the making, its furniture is all in, its laws are in perfect working order; and although wise men at various times have suggested improvements, there is on the whole a tolerably unanimous vote of confidence in things as they exist. The Divine Environment has little more to do for this planet so far as we can see, and so far as the existing generation is concerned. Then the lower organic life of the world is also so far complete. God, through Evolution or otherwise, may still have finishing touches to add here and there, but already it is "all very good." It is difficult to conceive anything better of its kind than a lily or a cedar, an ant or an ant-eater. These organisms, so far as we can judge, lack nothing. It might be said of them, "they are complete in Nature." Of man also, of man the animal, it may be affirmed that his Environment satisfies him. He has food and drink, and good food and good drink. And there is in him no purely animal want which is not really provided for, and that apparently in the happiest possible way
But the moment we pass beyond the mere animal life we begin to come upon an incompleteness. The symptoms at first are slight, and betray themselves only by an unexplained restlessness or a dull sense of want. Then the feverishness increases, becomes more defined, and passes slowly into abiding pain. To some come darker moments when the unrest deepens into a mental agony of which all the other woes of earth are mockeries -- moments when the forsaken soul can only cry in terror for the Living God. Up to a point the natural Environment supplies man's wants, beyond that it only derides him. How much in man lies beyond that point? Very much -- almost all, all that makes man man. The first suspicion of the terrible truth -- so for the time let us call it -- wakens with the dawn of the intellectual life. It is a solemn moment when the slow-moving mind reaches at length the verge of its mental horizon, and, looking over, sees nothing more. Its straining makes the abyss but more profound. Its cry comes back without an echo. Where is the Environment to complete this rational soul? Men either find one, -- One -- or spend the rest of their days in trying to shut their eyes. The alternatives of the intellectual life are Christianity or Agnosticism. The Agnostic is right when he trumpets his incompleteness. He who is not complete in Him must be for ever incomplete. Still more grave becomes man's case when he begins further to explore his moral and social nature. The problems of the heart and conscience are infinitely more perplexing than those of the intellect. Has love no future? Has right no triumph? Is the unfinished self to remain unfinished? Again, the alternatives are two, Christianity or Pessimism. But when we ascend the further height of the religious nature, the crisis comes. There, without Environment, the darkness is unutterable. So maddening now becomes the mystery that men are compelled to construct an Environment for themselves. No Environment here is unthinkable. An altar of some sort men must have -- God, or Nature, or Law. But the anguish of Atheism is only a negative proof of man's incompleteness. A witness more overwhelming is the prayer of the Christian. What a very strange thing, is it not, for man to pray? It is the symbol at once of his littleness and of his greatness. Here the sense of imperfection, controlled and silenced in the narrower reaches of his being, becomes audible. Now he must utter himself. The sense of need is so real, and the sense of Environment, that he calls out to it, addressing it articulately, and imploring it to satisfy his need. Surely there is nothing more touching in Nature than this? Man could never so expose himself, so break through all constraint, except from a dire necessity. It is the suddenness and unpremeditatedness of Prayer that gives it a unique value as an apologetic.
Man has three questions to put to his Environment, three symbols of his incompleteness. They come from three different centres of his being. The first is the question of the intellect, What is Truth? The natural Environment answers, "Increase of Knowledge increaseth Sorrow," and "much study is a Weariness." Christ replies, "Learn of Me, and ye shall find Rest." Contrast the world's word "Weariness" with Christ's word "Rest." No other teacher since the world began has ever associated "learn "with "Rest." Learn of me, says the philosopher, and you shall find Restlessness. Learn of Me, says Christ, and ye shall find Rest. Thought, which the godless man has cursed, that eternally starved yet ever living spectre, finds at last its imperishable glory; Thought is complete in Him. The second question is sent up from the moral nature, Who will show us any good? And again we have a contrast: the world's verdict, "There is none that doeth good, no, not one;" and Christ's, "There is none good but God only." And, finally, there is the lonely cry of the spirit, most pathetic and most deep of all, Where is he whom my soul seeketh? And the yearning is met as before, "I looked on my right hand, and beheld, but there was no man that would know me; refuge failed me; no man cared for my soul. I cried unto Thee, O Lord: I said, Thou art my refuge and my portion in the land of the living." 
Are these the directions in which men in these days are seeking to complete their lives? The completion of Life is just now a supreme question. It is important to observe how it is being answered. If we ask Science or Philosophy they will refer us to Evolution. The struggle for Life, they assure us, is steadily eliminating imperfect forms, and as the fittest continue to survive we shall have a gradual perfecting of being. That is to say, that completeness is to be sought for in the organism -- we are to be complete in Nature and in ourselves. To Evolution, certainly, all men will look for a further perfecting of Life. But it must be an Evolution which includes the factors. Civilization, it may be said, will deal with the second factor. It will improve the Environment step by step as it improves the organism, or the organism as it improves the Environment. This is well, and it will perfect Life up to a point. But beyond that it cannot carry us. As the possibilities of the natural Life become more defined, its impossibilities will become the more appalling. The most perfect civilization would leave the best part of us still incomplete. Men will have to give up the experiment of attempting to live in half an Environment. Half an Environment will give but half a Life. Half an Environment? He whose correspondences are with this world alone has only a thousandth part, a fraction, the mere rim and shade of an Environment, and only the fraction of a Life. How long will it take Science to believe its own creed, that the material universe we see around us is only a fragment of the universe we do not see? The very retention of the phrase "Material Universe," we are told, is the confession of our unbelief and ignorance; since "matter is the less important half of the material of the physical universe." 
The thing to be aimed at is not an organism self-contained and self-sufficient, however high in the scale of being, but an organism complete in the whole Environment. It is open to any one to aim at a self-sufficient Life, but he will find no encouragement in Nature. The Life of the body may complete itself in the physical world; that is its legitimate Environment. The Life of the senses, high and low, may perfect itself in Nature. Even the Life of thought may find a large complement in surrounding things. But the higher thought, and the conscience, and the religious Life, can only perfect themselves in God. To make the influence of Environment stop with the natural world is to doom the spiritual nature to death. For the soul, like the body, can never perfect itself in isolation. The law for both is to be complete in the appropriate Environment. And the perfection to be sought in the spiritual world is a perfection of relation, a perfect adjustment of that which is becoming perfect to that which is perfect.
The third problem, now simplified to a point, finally presents itself. Where do organism and Environment meet? How does that which is becoming perfect avail itself of its perfecting Environment? And the answer is, just as in Nature. The condition is simple receptivity. And yet this is perhaps the least simple of all conditions. It is so simple that we will not act upon it. But there is no other condition. Christ has condensed the whole truth into one memorable sentence, "As the branch cannot bear fruit of itself except it abide in the vine, no more can ye except ye abide in Me." And on the positive side, "He that abideth in Me the same bringeth forth much fruit."
