1 John 5:1-3

1 Whosoever believeth that Jesus is the Christ is born^[a] 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.
