Charles H. Spurgeon on Psalms 26:6

I will wash mine hands in innocency: so will I compass thine altar, O Lord. If greatness might have privileged this person from impurity, David was a king; if the grace of his soul might have freed him from the soil of sin, he was "a man after God's own heart." But let not great men put too much trust in their greatness; the longer the robe is the more soil in contracts: great power may prove the mother of great damnation. And as for purity, there is a generation that say there's no sin in them, but they deceive themselves; there is no truth in them. Whatever Rome's rusiologyi pretend for the power of nature, and of free will, we wretched sinners are taught to conceive more truly of our own infirmity. Christ's own apostle, stout Thomas, failed in the faith of his resurrection; Peter (whose chair is now the pretended seat of infallibility) denied his Master; David, "a man after God's own heart, "hath need of washing; and who can say, I am pure in the sight of the Lord? Certainly, O Lord, no flesh is righteous in thy sight. No; this is the best ground of Christian felicity, if with David we fall to a sight of our own sins; if with the Publican we strike our own breasts, and not with the Pharisee, cast our eye so much upon other men's faults. Why should we, like tailors, measure all men but ourselves? as if the best of us had not sin enough of his own to think on. See how David calls himself to account for his own sins; "O Lord, I know mine iniquity, and my sin is ever before me." Oh, the powerful effect of Christian devotion, when by the reflective act of the understanding, science is turned into conscience, and our knowledge is but the glass of our imperfection, the glass wherein the sight of our sins sends us presently to God, as it did David here, who makes this account only betwixt God and his own soul, "I, O Lord." First, he takes his rise from humility and the sight of his own sins, and he soars up by the wings of faith to the throne of God's mercy: "I, O Lord." He sees with his own eyes, and not only with the church, or the priest's spectacles; he is his own penitentiary and confessor; here's no intercession by saints, no masses, merits, indulgences, trentals, dirges: all's done betwixt God and him: "I, O Lord." With the eye of humility he looks to himself and his own misery; then with the eye of faith to God and his mercy, and from both these results a third virtue of repentance in the act of preparation, washing the soil of sin in the bath of sorrow: "I will wash mine hands, "etc. Isaac Bargrave.
