1 John 1:7-2:2

7But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, purifies us from all Or every sin. 8If we claim to be without sin, we deceive ourselves and the truth is not in us. 9If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. 10If we claim we have not sinned, we make him out to be a liar and his word is not in us.

1My dear children, I write this to you so that you will not sin. But if anybody does sin, we have an advocate with the Father—Jesus Christ, the Righteous One.

2He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world.
