1 John 5:6-9

5:6 Jesus 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. 5:7 For there are three that testify, 5:8 the Spirit and the water and the blood, and these three are in agreement.

5:9 If 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.
