And as a man of holiness prays for more holiness, so a man of holiness believes for more holiness. Psalm 51:7—in the Hebrew the words run in the future thus: "You will purge me from sin with hyssop, and I shall be clean: you will wash me, and I shall be whiter than snow." In the sense of all his sinfulness and vileness, he believes that God will give out greater measures of purity and sanctity to him: "You will purge me, and I shall be clean: you will wash me, and I shall be whiter than snow." Just so, in Psalm 65:3, "Iniquities prevail against me: as for our transgressions, you shall purge them away." Though for the present iniquity did prevail—yet he had faith enough to believe that God would purge him from his transgressions, and that he would mortify prevailing corruptions.
