1 John 1:7; 1 John 5:6; 1 John 5:8

1 John 1:7

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.

1 John 5:6

6 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.

1 John 5:8

8 And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one.
