'Be not conformed to this world; but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect will of God.' -- ROMANS xii.2.

I had occasion to point out, in a sermon on the preceding verse, that the Apostle is, in this context, making the transition from the doctrinal to the practical part of his letter, and that he lays down broad principles, of which all his subsequent injunctions and exhortations are simply the filling up of the details. One master word, for the whole Christian life, as we then saw, is sacrifice, self-surrender, and that to God. In like manner, Paul here brackets, with that great conception of the Christian life, another equally dominant and equally comprehensive. In one aspect, it is self-surrender; in another, it is growing transformation. And, just as in the former verse we found that an inward surrender preceded the outward sacrifice, and that the inner man, having been consecrated as a priest, by this yielding of himself to God, was then called upon to manifest inward consecration by outward sacrifice, so in this further exhortation, an inward 'renewing of the mind' is regarded as the necessary antecedent of transformation of outward life.

So we have here another comprehensive view of what the Christian life ought to be, and that not only grasped, as it were, in its very centre and essence, but traced out in two directions -- as to that which must precede it within, and as to that which follows it as consequence. An outline of the possibilities, and therefore the duties, of the Christian, is set forth here, in these three thoughts of my text, the renewed mind issuing in a transfigured life, crowned and rewarded by a clearer and ever clearer insight into what we ought to be and do.

I. Note, then, that the foundation of all transformation of character and conduct is laid deep in a renewed mind.

Now it is a matter of world-wide experience, verified by each of us in our own case, if we have ever been honest in the attempt, that the power of self-improvement is limited by very narrow bounds. Any man that has ever tried to cure himself of the most trivial habit which he desires to get rid of, or to alter in the slightest degree the set of some strong taste or current of his being, knows how little he can do, even by the most determined effort. Something may be effected, but, alas! as the proverbs of all nations and all lands have taught us, it is very little indeed. 'You cannot expel nature with a fork,' said the Roman. 'What's bred in the bone won't come out of the flesh,' says the Englishman. 'Can the Ethiopian change his skin or the leopard his spots?' says the Hebrew. And we all know what the answer to that question is. The problem that is set before a man when you tell him to effect self-improvement is something like that which confronted that poor paralytic lying in the porch at the pool: 'If you can walk you will be able to get to the pool that will make you able to walk. But you have got to be cured before you can do what you need to do in order to be cured.' Only one knife can cut the knot. The Gospel of Jesus Christ presents itself, not as a mere republication of morality, not as merely a new stimulus and motive to do what is right, but as an actual communication to men of a new power to work in them, a strong hand laid upon our poor, feeble hand with which we try to put on the brake or to apply the stimulus. It is a new gift of a life which will unfold itself after its own nature, as the bud into flower, and the flower into fruit; giving new desires, tastes, directions, and renewing the whole nature. And so, says Paul, the beginning of transformation of character is the renovation in the very centre of the being, and the communication of a new impulse and power to the inward self.

Now, I suppose that in my text the word 'mind' is not so much employed in the widest sense, including all the affections and will, and the other faculties of our nature, as in the narrower sense of the perceptive power, or that faculty in our nature by which we recognise, and make our own, certain truths. 'The renewing of the mind,' then, is only, in such an interpretation, a theological way of putting the simpler English thought, a change of estimates, a new set of views; or if that word be too shallow, as indeed it is, a new set of convictions. It is profoundly true that 'As a man thinketh, so is he.' Our characters are largely made by our estimates of what is good or bad, desirable or undesirable. And what the Apostle is thinking about here is, as I take it, principally how the body of Christian truth, if it effects a lodgment in, not merely the brain of a man, but his whole nature, will modify and alter it all. Why, we all know how often a whole life has been revolutionised by the sudden dawning or rising in its sky, of some starry new truth, formerly hidden and undreamed of. And if we should translate the somewhat archaic phraseology of our text into the plainest of modern English, it just comes to this: If you want to change your characters, and God knows they all need it, change the deep convictions of your mind; and get hold, as living realities, of the great truths of Christ's Gospel. If you and I really believed what we say we believe, that Jesus Christ has died for us, and lives for us, and is ready to pour out upon us the gift of His Divine Spirit, and wills that we should be like Him, and holds out to us the great and wonderful hopes and prospects of an absolutely eternal life of supreme and serene blessedness at His right hand, should we be, could we be, the sort of people that most of us are? It is not the much that you say you believe that shapes your character; it is the little that you habitually realise. Truth professed has no transforming power; truth received and fed upon can revolutionise a man's whole character.

So, dear brethren, remember that my text, though it is an analysis of the methods of Christian progress, and though it is a wonderful setting forth of the possibilities open to the poorest, dwarfed, blinded, corrupted nature, is also all commandment. And if it is true that the principles of the Gospel exercise transforming power upon men's lives, and that in order for these principles to effect their natural results there must be honest dealing with them, on our parts, take this as the practical outcome of all this first part of my sermon -- let us all see to it that we keep ourselves in touch with the truths which we say we believe; and that we thorough-goingly apply these truths in all their searching, revealing, quickening, curbing power, to every action of our daily lives. If for one day we could bring everything that we do into touch with the creed that we profess, we should be different men and women. Make of your every thought an action; link every action with a thought. Or, to put it more Christianlike, let there be nothing in your creed which is not in your commandments; and let nothing be in your life which is not moulded by these. The beginning of all transformation is the revolutionised conviction of a mind that has accepted the truths of the Gospel.

II. Well then, secondly, note the transfigured life.

The Apostle uses in his positive commandment, 'Be ye transformed,' the same word which is employed by two of the Evangelists in their account of our Lord's transfiguration. And although I suppose it would be going too far to assert that there is a distinct reference intended to that event, it may be permissible to look back to it as being a lovely illustration of the possibilities that open to an honest Christian life -- the possibility of a change, coming from within upwards, and shedding a strange radiance on the face, whilst yet the identity remains. So by the rippling up from within of the renewed mind will come into our lives a transformation not altogether unlike that which passed on Him when His garments did shine 'so as no fuller on earth could white them'; and His face was as the sun in his strength.

The life is to be transfigured, yet it remains the same, not only in the consciousness of personal identity, but in the main trend and drift of the character. There is nothing in the Gospel of Jesus Christ which is meant to obliterate the lines of the strongly marked individuality which each of us receives by nature. Rather the Gospel is meant to heighten and deepen these, and to make each man more intensely himself, more thoroughly individual and unlike anybody else. The perfection of our nature is found in the pursuit, to the furthest point, of the characteristics of our nature, and so, by reason of diversity, there is the greater harmony, and, all taken together, will reflect less inadequately the infinite glories of which they are all partakers. But whilst the individuality remains, and ought to be heightened by Christian consecration, yet a change should pass over our lives, like the change that passes over the winter landscape when the summer sun draws out the green leaves from the hard black boughs, and flashes a fresh colour over all the brown pastures. There should be such a change as when a drop or two of ruby wine falls into a cup, and so diffuses a gradual warmth of tint over all the whiteness of the water. Christ in us, if we are true to Him, will make us more ourselves, and yet new creatures in Christ Jesus.

And the transformation is to be into His likeness who is the pattern of all perfection. We must be moulded after the same type. There are two types possible for us: this world; Jesus Christ. We have to make our choice which is to be the headline after which we are to try to write. 'They that make them are like unto them.' Men resemble their gods; men become more or less like their idols. What you conceive to be desirable you will more and more assimilate yourselves to. Christ is the Christian man's pattern; is He not better than the blind, corrupt world?

That transformation is no sudden thing, though the revolution which underlies it may be instantaneous. The working out of the new motives, the working in of the new power, is no mere work of a moment. It is a lifelong task till the lump be leavened. Michael Angelo, in his mystical way, used to say that sculpture effected its aim by the removal of parts; as if the statue lay somehow hid in the marble block. We have, day by day, to work at the task of removing the superfluities that mask its outlines. Sometimes with a heavy mallet, and a hard blow, and a broad chisel, we have to take away huge masses; sometimes, with fine tools and delicate touches, to remove a grain or two of powdered dust from the sparkling block, but always to seek more and more, by slow, patient toil, to conform ourselves to that serene type of all perfectness that we have learned to love in Jesus Christ.

And remember, brethren, this transformation is no magic change effected whilst men sleep. It is a commandment which we have to brace ourselves to perform, day by day to set ourselves to the task of more completely assimilating ourselves to our Lord. It comes to be a solemn question for each of us whether we can say, 'To-day I am liker Jesus Christ than I was yesterday; to-day the truth which renews the mind has a deeper hold upon me than it ever had before.'

But this positive commandment is only one side of the transfiguration that is to be effected. It is clear enough that if a new likeness is being stamped upon a man, the process may be looked at from the other side; and that in proportion as we become liker Jesus Christ, we shall become more unlike the old type to which we were previously conformed. And so, says Paul, 'Be not conformed to this world, but be ye transformed.' He does not mean to say that the nonconformity precedes the transformation. They are two sides of one process; both arising from the renewing of the mind within.

Now, I do not wish to do more than just touch most lightly upon the thoughts that are here, but I dare not pass them by altogether. 'This world' here, in my text, is more properly 'this age,' which means substantially the same thing as John's favourite word 'world,' viz. the sum total of godless men and things conceived of as separated from God, only that by this expression the essentially fleeting nature of that type is more distinctly set forth. Now the world is the world to-day just as much as it was in Paul's time. No doubt the Gospel has sweetened society; no doubt the average of godless life in England is a better thing than the average of godless life in the Roman Empire. No doubt there is a great deal of Christianity diffused through the average opinion and ways of looking at things, that prevail around us. But the World is the world still. There are maxims and ways of living, and so on, characteristic of the Christian life, which are in as complete antagonism to the ideas and maxims and practices that prevail amongst men who are outside of the influences of this Christian truth in their own hearts, as ever they were.

And although it can only be a word, I want to put in here a very earnest word which the tendencies of this generation do very specially require. It seems to be thought, by a great many people, who call themselves Christians nowadays, that the nearer they can come in life, in ways of looking at things, in estimates of literature, for instance, in customs of society, in politics, in trade, and especially in amusements -- the nearer they can come to the un-Christian world, the more 'broad' (save the mark!) and 'superior to prejudice' they are. 'Puritanism,' not only in theology, but in life and conduct, has come to be at a discount in these days. And it seems to be by a great many professing Christians thought to be a great feat to walk as the mules on the Alps do, with one foot over the path and the precipice down below. Keep away from the edge. You are safer so. Although, of course, I am not talking about mere conventional dissimilarities; and though I know and believe and feel all that can be said about the insufficiency, and even insincerity, of such, yet there is a broad gulf between the man who believes in Jesus Christ and His Gospel and the man who does not, and the resulting conducts cannot be the same unless the Christian man is insincere.

III. And now lastly, and only a word, note the great reward and crown of this transfigured life.

Paul puts it in words which, if I had time, would require some commenting upon. The issue of such a life is, to put it into plain English, an increased power of perceiving, instinctively and surely, what it is God's will that we should do. And that is the reward. Just as when you take away disturbing masses of metal from near a compass, it trembles to its true point, so when, by the discipline of which I have been speaking, there are swept away from either side of us the things that would perturb our judgment, there comes, as blessing and reward, a clear insight into that which it is our duty to do.

There may be many difficulties left, many perplexities. There is no promise here, nor is there anything in the tendencies of Christ-like living, to lead us to anticipate that guidance in regard to matters of prudence or expediency or temporal advantage will follow from such a transfigured life. All such matters are still to be determined in the proper fashion, by the exercise of our own best judgment and common-sense. But in the higher region, the knowledge of good and evil, surely it is a blessed reward, and one of the highest that can be given to a man, that there shall be in him so complete a harmony with God that, like God's Son, he 'does always the things that please Him,' and that the Father will show him whatsoever things Himself doeth; and that these also will the son do likewise. To know beyond doubt what I ought to do, and knowing, to have no hesitation or reluctance in doing it, seems to me to be heaven upon earth, and the man that has it needs but little more. This, then, is the reward. Each peak we climb opens wider and clearer prospects into the untravelled land before us.

And so, brethren, here is the way, the only way, by which we can change ourselves, first let us have our minds renewed by contact with the truth, then we shall be able to transform our lives into the likeness of Jesus Christ, and our faces too will shine, and our lives will be ennobled, by a serene beauty which men cannot but admire, though it may rebuke them. And as the issue of all we shall have clearer and deeper insight into that will, which to know is life, in keeping of which there is great reward. And thus our apostle's promise may be fulfilled for each of us. 'We all with unveiled faces reflecting' -- as a mirror does -- 'the glory of the Lord, are changed ... into the same image.'
