If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness.
and to cleanse us, from all unrighteousness, is but the same thing expressed in different words; for all unrighteousness is sin, and to cleanse from sin is to remove the guilt of it, by an application of the blood of Christ for pardon. The antecedent to the relative "he" in the text, is either God, who is light, and with whom the saints have fellowship; or his Son Jesus Christ, who is the nearest antecedent, and who, being truly God, has a power to forgive sin.
