¹ Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth him that begat loveth him also that is begotten of him.

² By this we know that we love the children of God, when we love God, and keep his commandments.

For this is the love of God, that we keep his commandments: and his commandments are not grievous.

⁴ For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith.

⁵ Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?
