1 John 5:4-8

4For whatever is born of God overcomes the world. And this is the victory that has overcome the world—our faith.

5Who is he who overcomes the world, but he who believes that Jesus is the Son of God?

6This is He who came by water and blood—Jesus Christ; not only by water, but by water and blood. And it is the Spirit who bears witness, because the Spirit is truth.

7For there are three that bear witness in heaven: the Father, the Word, and the Holy Spirit; and these three are one.

8And there are three that bear witness on earth: the Spirit, the water, and the blood; and these three agree as one.
