An Account of the Nature and Measures of Conscience
1 John 3:19-22
And hereby we know that we are of the truth, and shall assure our hearts before him.…


As nothing can be of more moment, so few things, doubtless, are of more difficulty, than for men to be rationally satisfied about the estate of their souls, with reference to God and the great concerns of eternity. First of all then: he who would pass such a judgment upon his condition as shall be ratified in heaven, will find himself wofully deceived, if he judges of his spiritual estate by any of these measures.

1. The general esteem of the world concerning him. He who owes his piety to fame and hearsay, and the evidences of his salvation to popular voice and opinion, builds his house not only upon the sand, but, which is worse, upon the wind; and writes the deeds, by which he holds his estate, upon the face of a river. The favourable opinion and good word of men, to some persons especially, comes oftentimes at a very easy rate; and by a few demure looks.

2. The judgment of any casuist or learned divine, concerning the estate of a man's soul, is not sufficient to give him confidence towards God. And the reason is because no learning whatsoever can give a man the knowledge of another's heart.

3. The absolution pronounced by a priest is not a certain, infallible ground, to give the person so absolved confidence towards God, because if absolution, as such, could of itself secure a man, as to the estate of his soul, then it would follow that every person so absolved should, by virtue thereof, be ipso facto put into such a condition of safety; which is not imaginable. In a word, if a man be penitent, his repentance stamps his absolution effectual. If not, let the priest repeat the same absolution to him ten thousand times; yet for all his being absolved in this world, God will condemn him in the other.

4. No advantages from external church membership, or profession of the true religion, can of themselves give a man confidence towards God: and yet perhaps there is hardly any one thing in the world which men, in all ages, have generally more cheated themselves with. Thus I have shown four several uncertain rules, which men are prone to judge of their spiritual estate by. But now have we any more certain to substitute and recommend in the room of them? Why, yes; if we believe the apostle, a man's own heart or conscience is that which, above all other things, is able to give him "confidence towards God." And the reason is, because the heart knows that by itself, which nothing in the world besides can give it any knowledge of; and without the knowledge of which it can have no foundation to build any true confidence upon.

I. HOW THE HEART OR CONSCIENCE OUGHT TO BE INFORMED, IN ORDER TO ITS FOUNDING IN US A RATIONAL CONFIDENCE TOWARDS GOD. It is not necessary for a man to be assured of the rightness of his conscience, by such an infallible certainty of persuasion, as amounts to the clearness of a demonstration; but it is sufficient if he knows it upon grounds of such a convincing probability, as shall exclude all rational grounds of doubting of it. There is an innate light in every man, discovering to him the first lines of duty in the common notions of good and evil; which by cultivation may be advanced to higher discoveries. He therefore who exerts all the faculties of his soul, and plies all means and opportunities in the search of truth, which God has vouchsafed him, may rest upon the judgment of his conscience so informed, as a warrantable guide of those actions which he must account to God for.

II. HOW, AND BY WHAT MEANS, WE MAY GET OUR HEART OR CONSCIENCE THUS INFORMED, AND AFTERWARDS PRESERVE AND KEEP IT SO.

1. Let a man carefully attend to the voice of his reason, and all the dictates of natural morality; so by no means to do anything contrary to them. For though reason is not to be relied upon, as a guide universally sufficient to direct us what to do; yet it is generally to be relied upon and obeyed, where it tells us what we are not to do. No man ever yet offended his own conscience, but first or last it was revenged upon him for it. So that it will concern a man to treat this great principle awfully and warily, by still observing what it commands, but especially what it forbids: and if he would have it always a faithful and sincere monitor to him, let him be sure never to turn a deaf ear to it; for not to hear it is the way to silence it. Let him strictly observe the first stirrings and intimations, the first hints and whispers of good and evil that pass in his heart; and this will keep conscience so quick and vigilant, and ready to give a man true alarms upon the least approach of his spiritual enemy, that he shall be hardly capable of a great surprise.

2. Let a man be very tender, and regardful of every pious motion and suggestion made by the Spirit of God in his heart.

3. Because the light of natural conscience is in many things defective and dim, and the internal voice of God's Spirit not always distinguishable, above all, let a man attend to the mind of God uttered in His revealed Word. We shall find it a rule, both to instruct us what to do, and to assure us in what we have done. For though natural conscience ought to be listened to, yet it is revelation alone that is to be relied upon: as we may observe in the works of art, a judicious artist will indeed use his eye, but he will trust only to his rule. There is not any one action whatsoever which a man ought to do or to forbear, but the Scripture will give him a clear precept or prohibition for it.

4. The fourth and last way that I shall mention for the getting of the conscience rightly informed, and afterwards keeping it so, is frequently and impartially to account with it. It is with a man and his conscience as with one man and another, amongst whom we used to say that "even reckoning makes lasting friends," and the way to make reckonings even, I am sure, is to make them often. I shall close with this twofold caution.

(1) Let no man think that every doubting or misgiving about the safety of his spiritual estate overthrows the confidence hitherto spoken of. The sincerity of our faith or confidence will not secure us against all vicissitudes of wavering or distrust; indeed, no more than a strong athletic constitution of body will secure a man always against heats, and colds, and such like indispositions.

(2) Let no man from what has been said reckon a bare silence of conscience, in not accusing or disturbing him, a sufficient argument for confidence towards God. For such a silence is so far from being always so, that it is usually worse than the fiercest and loudest accusations; since it may, and for the most part does, proceed from a kind of numbness or stupidity of conscience; and an absolute dominion obtained by sin over the soul; so that it shall not so much as dare to complain or make a stir.

(R. South, D. D.)
