1 John 1:10 DBY

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 is faithful and righteous to 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.
