1 John 5:6-9

6Jesus Christ — he is the one who came by water and blood, not by water only, but by water and by blood. And the Spirit is the one who testifies, because the Spirit is the truth.

7For there are three that testify:

8the Spirit, the water, and the blood  — and these three are in agreement.

9If we accept human testimony, God’s testimony is greater, because it is God’s testimony that he has given about his Son.
