1 John 1:8-10

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 a liar out of God, and his word is not in us.
