If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness.
Were any one to object and say, that as long as we sojourn in the world, we are never cleansed from all unrighteousness, with regard to our reformation: this is indeed true; but John does not refer to what God now performs in us. He is faithful, he says, to cleanse us, not today or tomorrow; for as long as we are surrounded with flesh, we ought to be in a continual state of progress; but what he has once begun, he goes on daily to do, until he at length completes it. So Paul says, that we are chosen, that we may appear without blame before God, (Colossians 1:22;) and in another place he says, that the Church is cleansed, that it might be without spot or wrinkle. (Ephesians 5:27.)
