a Bible passage
20. For if our heart condemn us He proves, on the other hand, that they in vain possess the name and appearance of Christians, who have not the testimony of a good conscience. For if any one is conscious of guilt, and is condemned by his own heart, much less can he escape the judgment of God. It hence follows, that faith is subverted by the disquiet of an evil conscience.
He says, that God is greater than our heart, with reference to judgment, that is, because he sees much more keenly than we do, and searches more minutely and judges more severely. For this reason, Paul says, that though he was not conscious of wrong himself, yet he was not therefore justified, (1 Corinthians 4:4;) for he knew that however carefully attentive he was to his office, he erred in many things, and through inadvertence was ignorant of mistakes which God perceived. What then the Apostle means is, that he who is harassed and condemned by his own conscience, cannot escape the judgment of God.
To the same purpose is what immediately follows, that God knoweth or seeth all things For how can those things be hid from him which we, who in comparison with him are dull and blind, are constrained to see? Then take this explanation, “Since God sees all things, he is far superior to our hearts.” For to render a copulative as a causal particle is no new thing. The meaning is now clear, that since the knowledge of God penetrates deeper than the perceptions of our conscience, no one can stand before him except the integrity of his conscience sustains him.
But here a question may be raised. It is certain that the reprobate are sometimes sunk by Satan into such stupor, that they are no longer conscious of their own evils, and. without alarm or fear, as Paul says, rush headlong into perdition; it is also certain, that hypocrites usually flatter themselves, and proudly disregard the judgment of God, for, being inebriated by a false conceit as to their own righteousness, they feel no convictions of sin. The answer to these things is not difficult; hypocrites are deceived because they shun the light; and the reprobate feel nothing, because they have departed from God; and, indeed there is no security for an evil conscience but in hiding-places.
But the Apostle speaks here of consciences which God draws forth to the light, forces to his tribunal, and fills with an apprehension of his judgment. Yet; it is at the same time generally true, that we cannot have a calm peace except that which God’s Spirit gives to purified hearts; for those who, as we have said, are stupefied, often feel secret compunctions, and torment themselves in their lethargy.
