Let no one then, [even] of those who are come to the extremest wickedness, despair of himself. For (He says) even if thou hast passed into the habit, yea and almost into the nature of wickedness itself, be not afraid. Therefore taking [the instance of] colors that are not superficial but almost of the substance of the materials, He said that He would bring them into the opposite state. For He did not simply say that He would “wash” us, but that He would “make” us “white, as snow and as wool,” in order to hold out good hopes before us. Great then is the power of repentance, at least if it makes us as snow, and whitens us as wool, even if sin have first got possession and dyed our souls.
