1 John 1:8-2:2

New Revised Standard Version, Anglicised

⁸ If we say that we have no sin, we deceive ourselves, and the truth is not in us. ⁹ If we confess our sins, he who is faithful and just will forgive us our sins and cleanse us from all unrighteousness. ¹⁰ If we say that we have not sinned, we make him a liar, and his word is not in us.

Christ Our Advocate

2 My little children, I am writing these things to you so that you may not sin. But if anyone does sin, we have an advocate with the Father, Jesus Christ the righteous; ² and he is the atoning sacrifice for our sins, and not for ours only but also for the sins of the whole world.
