If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.
God's forgiveness is guaranteed when we confess. He is faithful to His promise and just in His character. He doesn't just forgive—He purifies us, making us clean and new.
As far as the east is from the west, so far has he removed our transgressions from us.
God doesn't just forgive—He removes our sins completely. The distance between east and west is infinite; that's how far God separates us from our forgiven sins. They are gone forever.
