If we say that we have no sin, we deceive ourselves, and the truth is not in us. – 1John 1:8
Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived… – 1Corinthians 6:9
Be not deceived; God is not mocked… – Galatians 6:7
While the man who has deceived himself says, “I have no sin,” he has not deceived the Lord. God sees sin in us if we do not. The ostrich is reported to bury her head in the sand, and then to suppose herself safe, but she is the more speedily taken; and we may shut our eyes and say, “I have no sin,” but in so doing instead of securing eternal salvation we shall as practically give ourselves up to the destroyer as the bird of the desert is fabled to do. Let a man say, “I have no sin,” and he has condemned himself out of his own mouth, for the text says of such a man the truth is not in him, and he who hath not truth in him is not saved. The absence of confession of present sin means the absence of the light of truth, and sincerity. All sorts of people God saves, however black their sins, but the man of a false spirit, the Pharisaic washer of the outside of the cup, while the inside is foul, is the last person who is likely to be saved. A main point in conversion consists in a man’s being honest, for it is the honest and good ground which receives the seed. If you preach the gospel among the roughest and most profane of men, there is more hope of success among them than among hypocritical professors. Open enmity and opposition are better than that pretended friendship which begins and ends with the shallow compliments of empty formalism. Outward religiousness, unattended by heart piety, does a man serious injury, by rendering him superficial and unreal in all that he does in reference to God, and as God desires truth in the inward parts He will not parley with dishonest men. Pretend and profess and boast what ye will, but this know, that the living God abhors everything which is not according to the strictest truth.
