he is faithful

"God is faithful"

to forgive us our sins and cleanse us from all unrighteousness

These two phrases mean basically the same thing. John uses them to emphasize that God will surely forgive our sins. Alternate translation: "and will completely forgive us for what we have done wrong" (See: rc://en/ta/man/jit/figs-parallelism)
