For whoever is born of God overcomes the world: and this is the victory that overcomes the world, even our faith. Who is he that overcomes the world, but he that believes that Jesus is the Son of God? This is he that came by water and blood, even Jesus Christ; not by water only, but by water and blood. And it is the Spirit that bears witness, because the Spirit is truth. For there are three that bear witness in heaven, the Father, the Word, and the Holy Spirit: and these three are one. And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one. If we receive the witness of men, the witness of God is greater: for this is the witness of God which he has testified of his Son. (1 John 5:4-9)
