1 John 5:6-9

Goodspeed(i) 6 It was he, Jesus Christ himself, who came in water and in blood; not in water only, but in water and in blood. The Spirit also testifies to this, for the Spirit is truth. 7 For there are three that testify to it, 8 the Spirit, the water, and the blood, and the three are at one. 9 If we accept the testimony of men, the testimony of God is stronger still; for the value of God's testimony lies in this, that he has testified to his Son.
