13 In this we know that we abide in him, and he in us: because he hath given us of his spirit.

14 And we have seen and do testify that the Father hath sent his Son to be the Saviour of the world.

15 Whosoever shall confess that Jesus is the Son of God, God abideth in him, and he in God.

16 And we have known and have believed the charity which God hath to us. God is charity: and he that abideth in charity abideth in God, and God in him.

17 In this is the charity of God perfected with us, that we may have confidence in the day of judgment: because as he is, we also are in this world.

18 Fear is not in charity: but perfect charity casteth out fear, because fear hath sin. And he that feareth is not perfected in charity.

19 Let us therefore love God: because God first hath loved us.

20 If any man say: I love God, and hateth his brother; he is a liar. For he that loveth not his brother whom he seeth, how can he love God whom he seeth not?

21 And this commandment we have from God, that he who loveth God love also his brother.
