Though your sins be like scarlet, they may be as white as snow; though they be red like crimson, they shall be as wool (Isaiah 1:18).
O, the boundless mercy of God! In His greatest wrath upon the faithless and ungrateful people, upon the people "laden with iniquity, a seed of evildoers, children that are corrupters" (Isaiah 1:4), as "princes [rulers] of Sodom" (Isaiah 1:10) and upon the people who have become as the "people of Gomorrah" (Isaiah 1:10) - in such wrath, the Lord does not abandon mercy but rather calls them to repentance. Just as after terrible lightnings, a gentle rain falls. Such is the Lord long-suffering [patient] and full of mercy and "neither will He keep His anger forever" (Psalm 103:9). Only if sinners cease to commit evil and learn to do good and turn to God with humility and repentance they will become "white as snow." The Lord is mighty and willing. No one, except Him, is able to cleanse the sinful soul of man from sin and, by cleansing, to whiten it.
