Wash yourselves clean! Cease doing evil; learn to do good. Make justice your aim: redress the wronged, hear the orphan’s plea, defend the widow. Though your sins be like scarlet, they may become white as snow; Though they be crimson red, they may become white as wool. (Is 1:10, 16-20)

Normally, when we confess our sins, we rarely include failing to do the works of justice. But it precisely the works of justice . . . that are the way of salvation.
