If we claim to be without sin, we deceive ourselves and the truth is not in us.
If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.
If we claim we have not sinned, we make him out to be a liar and his word has no place in our lives.
My dear children, I write this to you so that you will not sin. But if anybody does sin, we have one who speaks to the Father in our defense--Jesus Christ, the Righteous One.
He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world.
