3 We proclaim to you what we have seen and heard, so that you also may have fellowship with us. And our fellowship is with the Father and with his Son, Jesus Christ.
4 We write this to make oura joy complete.

Light and Darkness, Sin and Forgiveness

5 This is the message we have heard from him and declare to you: God is light; in him there is no darkness at all.
6 If we claim to have fellowship with him and yet walk in the darkness, we lie and do not live out the truth.
7 But 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 allb sin.
8 If we claim to be without sin, we deceive ourselves and the truth is not in us.
9 If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.
10 If we claim we have not sinned, we make him out to be a liar and his word is not in us.
