Charles H. Spurgeon on Psalms 32:5

Thou forgavest the iniquity of my sin. This sin seems very probably to have been his adultery with Bathsheba, and murder of Uriah. Now David, to make the pardoning mercy of God more illustrious, saith he did not only forgive his sin, but the iniquity of his sin; and what was that? Surely the worst that can be said of that, his complicated sin, is that there was so much hypocrisy in it, he woefully juggled with God and man in it; this, I do not doubt to say, was the iniquity of his sin, and put a colour deeper on it than the blood which he shed. And the rather —I lay the accent there —because God himself, when he would set out the heinousness of this sin, seems to do it rather from the hypocrisy in the fact than the fact itself, as appears by the testimony given this holy man 1Ki 15:5: "David did that which was right in the eyes of the Lord, and turned not aside from any thing that he commanded him all the days of his life, save only in the matter of Uriah the Hittite." Were there not other false steps which David took beside this? Doth the Spirit of God, by excepting this, declare his approbation of all that else he ever did? No, sure the Spirit of God records other sins that escaped this eminent servant of the Lord; but all those are drowned here, and this mentioned is the only stain of his life. But why? Surely because there appeared less sincerity, yea, more hypocrisy in this one sin than in all his others put together; though David in them was wrong as to the matter of his actions, yet his heart was more right in the manner of committing them. But here his sincerity was sadly wounded, though not to the total destruction of the habit, yet to lay it in a long swoon, as to any actings thereof. And truly the wound went very deep when that grace was stabbed in which did run the life blood of all the rest. We see, then, God hath reason, though his mercy prompted him, yea, his covenant obliged him, not to let his child die of this wound, yet so to heal it that a scar might remain upon the place, a mark upon the sin, whereby others might know how odious hypocrisy is to God.
