1 John 1:5-7

5 This is the message we have heard from him and proclaim to you, that God is light and in him is no darkness at all.

6 If we say we have fellowship with him while we walk in darkness, we lie and do not live according to 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 cleanses us from all sin.
