Charles H. Spurgeon on Psalms 32:5

I said, I will confess my transgressions unto the Lord; and thou forgavest the iniquity of my sin. Be thine own accuser in the free confession of thy sins. Peccavi pater (as the prodigal child), "Father, I have sinned against heaven, and in thy sight." For it fares not in the court of heaven as it doth in our earthly tribunals. With men a free confession makes way for a condemnation; but with God, the more a sinner bemoans his offence, the more he extenuates the anger of his Judge. Sin cannot but call for justice, as it is an offence against God; yet, when once it is a wound to the soul it moveth him to mercy and clemency. Wherefore as David having but resolved to confess his sins, was accosted eftsoon with an absolution: so, Tu agnosce, et Dominus ignoscet (Augustine.) Be thou unfeigned in confessing, and God will be faithful in forgiving. 1Jo 1:9. Only let confessio peccati be professo desinendi (Hilary.) —the acknowledgment of thy sin an obligation to leave it; and then thou mayest build upon it. "He that confesseth and forsaketh shall have mercy." Pr 28:13. Isaac Craven's Sermon at Paul's Cross, 1630
