1 John 1:7; 1 John 5:6; 1 John 5:8
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.
This is he that came by water and blood, even Jesus Christ; not by water only, but by water and blood. And it is the Spirit that beareth witness , because the Spirit is truth.
And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one.
