1 John 1:3-7
3That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ.
4And these things write we unto you, that your joy may be full.
5This 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.
6If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth:
7But 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.
(KJV)
