1 John 1:5-2:2New International Version (NIV)

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 all^[a] 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.

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