1 John 1:5-7

5 And this is the telling, that we heard of him, and tell to you, that God is light, and there be no darknesses in him.

6 If we say, that we have fellowship with him, and we wander in darknesses, we lie, and do not truth.

7 But if we walk in light, as also he is in light, we have fellowship together; and the blood of Jesus Christ, his Son, cleanseth us from all sin.
