1 John 5:1, 6-8

Everyone who believes that Jesus is the Christ has become a child of God. And everyone who loves the Father loves his children, too.

And Jesus Christ was revealed as God’s Son by his baptism in water and by shedding his blood on the cross—not by water only, but by water and blood. And the Spirit, who is truth, confirms it with his testimony. So we have these three witnesses— the Spirit, the water, and the blood—and all three agree.
