Charles H. Spurgeon on Psalms 19:12

"Who can understand his errors?" After this survey of the works and word of God, he comes at last to peruse the third book, his conscience; a book which though wicked men may keep shut up, and naturally do not love to look into it, yet will one day be laid open before the great tribunal in the view of the whole world, to the justifying of God when he judges, and to impenitent sinners' eternal confusion. And what finds he here? A foul, blurred copy that he is puzzled how to read; "who," says he, "can understand his errors?" Those notions which God had with his own hand imprinted upon conscience in legible characters, are partly defaced and slurred with scribble, and interlinings of "secret faults;" partly obliterated and quite razed out with capital crimes, "presumptuous sins." And yet this manuscript cannot be so abused, but it will still give in evidence for God; there being no argument in the world that can with more force extort an acknowledgment of God from any man's conscience than the conviction of guilt itself labours under. For the sinner cannot but know he has transgressed a law, and he finds within him, if he is not past all sense, such apprehensions that though at present he "walk in the ways of his heart and in the sight of his eyes" (as the wise man ironically advises the young man to do, Ecclesiastes 11:9), yet he knows (as the same wise man there from his own experience tells him) that "for all these things God will bring him into judgment." The conscience being thus convicted of sin, where there is any sense of true piety the soul will, with David, here address itself to God for pardon, that it may be "cleansed from secret faults;" and for grace, that by its restraints, and preventions, and assistances, it may be "kept back from presumptuous sins," and if unhappily engaged, that it may be freed at least from the "dominion" of them —"Keep back thy servant also from presumptuous sins; let them not have dominion over me," etc. —Adam Littleton.
