1 John 5:6-9

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

7For there are three that testify,

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

9If we accept the testimony of men, the testimony of God is greater, because this is the testimony of God that he has testified concerning his Son.
