Psalms 32:3

It is very difficult to bring sinful man humbly to accept free mercy, with a full confession of his sins and self-condemnation. But the true and only way to peace of conscience, is, to confess our sins, that they may be forgiven; to declare them that we may be justified. Although repentance and confession do not merit the pardon of transgression, they are needful to the real enjoyment of forgiving mercy. And what tongue can tell the happiness of that hour, when the soul, oppressed by sin, is enabled freely to pour forth its sorrows before God, and to take hold of his covenanted mercy in Christ Jesus! Those that would speed in prayer, must seek the Lord, when, by his providence, he calls them to seek him, and, by his Spirit, stirs them up to seek him. In a time of finding, when the heart is softened with grief, and burdened with guilt; when all human refuge fails; when no rest can be found to the troubled mind, then it is that God applies the healing balm by his Spirit.

When I kept silence. When through neglect I failed to confess, or through despair dared not do so, my bones, those solid pillars of my frame, the stronger portions of my bodily constitution, waxed old, began to decay with weakness, for my grief was so intense as to sap my health and destroy my vital energy. What a killing thing is sin! It is a pestilent disease! A fire in the bones! While we smother our sin it rages within, and like a gathering wound swells horribly and torments terribly. Through my roaring all the day long. He was silent as to confession, but not as to sorrow. Horror at his great guilt, drove David to incessant laments, until his voice was no longer like the articulate speech of man, but so full of sighing and groaning, that it resembled to hoarse roaring of a wounded beast. None knows the pangs of conviction but those who have endured them. The rack, the wheel, the flaming fagot are ease compared with the Tophet which a guilty conscience kindles within the breast: better suffer all the diseases which flesh is heir to, than lie under the crushing sense of the wrath of almighty God. The Spanish inquisition with all its tortures was nothing to the inquest which conscience holds within the heart.
