5 This is the message that we have heard from him and declare to you: God is light, and in him there is no darkness—none at all!
6 If we claim that we have fellowship with him but keep living in the darkness, we are lying and the truth is not in us.
7 But if we keep living in the light as he himself is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin.
