1 John 5:1

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.

³  For this is the love of God, that we keep his commandments: and his commandments are not grievous.
