5 Moreover, this is the message which we have heard from him, and declare to you, that God is light, and in him is no darkness at all.
6 If we say that we have fellowship with him, and walk in darkness, we lie, and obey not 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 Christ the Son cleanses us from all sin.
