5:1 Everyone who believes that Jesus is the Christ has been born of God, and everyone who loves the Father loves whoever has been born of him. 2 By this we know that we love the children of God, when we love God and obey his commandments. 3 For this is the love of God, that we keep his commandments. And his commandments are not burdensome. 4 For everyone who has been born of God overcomes the world. And this is the victory that has overcome the world—our faith. 5 Who is it that overcomes the world except the one who believes that Jesus is the Son of God?

6 This is he who came by water and blood—Jesus Christ; not by the water only but by the water and the blood. And the Spirit is the one who testifies, because the Spirit is the truth. (ESV)
