1 John 1:5-8

5 This then is the message which we have heard of him, and declare unto 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 do not the truth:

7 But if we walk in the light, as he is in the light, we have fellowship one with another*, and the blood of Jesus Christ his Son cleanseth us from all sin.

8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
