In context
Before · 1 John 1:6–7
6If we say that we have fellowship with him and walk in the darkness, we lie and don’t tell the truth. 7But if we walk in the light as he is in the light, we have fellowship with one another, and the blood of Jesus Christ his Son cleanses us from all sin.
8If we say that we have no sin, we deceive ourselves, and the truth is not in us.
