1 John 5:1, 6-8

Everyone who believes that Jesus is the Messiah is God’s spiritual child and has been fathered by God himself. And everyone who loves Father God loves his children as well.

Jesus Christ is the One who was revealed as God’s Son by his water baptism and by the blood of his cross—not by water only, but by water and blood. And the Spirit, who is truth, confirms this with his testimony. So we have these three constant witnesses giving their evidence: the Spirit, the water, and the blood. And these three are in agreement.
