7 But if we live in the light — just as he is in the light — then we have fellowship with one another, and the blood of Jesus, his Son, purifies us from every sin.
8 If we say that we have no sin, we deceive ourselves, and there is no truth in us.
9 But if we confess our sins to God, he will keep his promise and do what is right: he will forgive us our sins and purify us from all our wrongdoing.
10 If we say that we have not sinned, we make God out to be a liar, and his word is not in us.
