Commending ourselves to every man’s conscience – That is, so speaking the truth that every man’s conscience shall approve it “as” true; every man shall see it to be true, and to be in accordance with what he knows to be right. Conscience is that faculty of the mind which distinguishes between right and wrong, and which prompts us to choose the former and avoid the latter; John 8:9; Romans 2:15 note; 1 Corinthians 10:25, 1 Corinthians 10:27-29 notes; 2 Corinthians 1:12 note. It is implied here:
(1) That a course of life, and a manner of preaching that shall be free from dishonesty, and art, and trick, will be such as the consciences of people will approve. Paul sought such a course of life as should accord with their sense of “right,” and thus serve to commend the gospel to them.
(2) that the gospel may be so preached as to be seen by men to be true; so as to be approved as right; and so that every man’s conscience shall bear testimony to its truth. People do not “love” it, but they may see that it is “true;” they may hate it, but they may see that the truth which condemns their practices is from heaven. This is an exceedingly important principle in regard to preaching, and vastly momentous in its bearing on the views which ministers should have of their own work. The gospel is reasonable. It may be seen to be true by every man to whom it is preached. And it should be the aim of every preacher so to preach it, as to enlist the consciences of his hearers in his layout. And it is a very material fact that when so preached the conscience and reason of every man is in its favor, and they know that it is true even when it pronounces their own condemnation, and denounces their own sins. This passage proves, therefore, the following things:
(1) That the gospel may be so preached as to be seen to be true by all people. People are capable of seeing the truth, and even when they do not love it; they can perceive that it has demonstration that it is from God. It is a system so reasonable; so well established by evidence; so fortified by miracles, and the fulfillment of prophecies; so pure in its nature; so well-adapted to man; so suited to his condition, and so well designed to make him better; and so happy in its influence on society, that people may be led to see that it is true. And this I take to be the case with almost all those people who habitually attend on the preaching of the gospel. Infidels do not often visit the sanctuary; and when they are in the habit of doing it, it is a fact that they gradually come to the conviction that the Christian religion is true. It is rare to find professed infidels in our places of worship; and the great mass of those who attend on the preaching of the gospel may be set down as speculative believers in the truth of Christianity.
(2) the consciences of people are on the side of truth, and the gospel may be so preached as to enlist their consciences in its favor. Conscience prompts to do right, and condemns us if we do wrong. It can never be made to approve of wrong, never to give a man peace if he does that which he knows to be evil. By no art or device; by no system of laws, or bad government; by no training or discipline, can it be made the advocate of sin. In all lands, at all times, and in all circumstances, it prompts a man to do what is right, and condemns him if he does wrong. It may be silenced for a time; it may be “seared as with a hot iron,” and for a time be insensible, but if it speak at all, it speaks to prompt a man to do what he believes to be right, and condemns him if he does that which is wrong. The consciences of people are on the side of the gospel; and it is only their hearts which are opposed to it. Their consciences are in favor of the gospel in the following, among other respects:
(a) They approve of it as a just, pure, holy, and reasonable system; as in accordance with what they feel to be right; as recommending that which ought to be done, and forbidding that which ought not to be done.
(b) In its special requirements on themselves. Their consciences tell them that they ought to love God with all the heart; to repent of their sins; to trust in that Saviour who died for them; and to lead a life of prayer and of devotedness to the service of God; that they ought to be sincere and humble Christians, and prepare to meet God in peace.
(c) Their consciences approve the truth that condemns them. No matter how strict it may seem to be; no matter how loud its denunciation against their sins; no matter how much the gospel may condemn their pride, avarice, sensuality, levity, dishonesty, fraud, intemperance, profaneness, biasphemy, or their neglect of their soul, yet their consciences approve of it as right, and proclaim that these things ought to be condemned, and ought to be abandoned. The heart may love them, but the conscience cannot be made to approve them. And the minister of the gospel may “always” approach his people, or an individual man, with the assurance that however much they may “love” the ways of sin, yet that he has their consciences in his favor, and that in urging the claims of God on them, their “consciences” will always coincide with his appeals.
