13. Hereby we know that we abide in him and he in us, that he has given to us of his Spirit.
14. And we have seen, and testify, that the Father has sent the Son as Saviour of the world.
15. Whosoever shall confess that Jesus is the Son of God, God abides in him, and he in God.
16. And we have known and have believed the love which God has to us. God is love, and he that abides in love abides in God, and God in him.
17. Herein has love been perfected with us that we may have boldness in the day of judgment, that even as he is, we also are in this world.
18. There is no fear in love, but perfect love casts out fear; for fear has torment, and he that fears has not been made perfect in love.
19. We love because he has first loved us.
20. If any one say, I love God, and hate his brother, he is a liar: for he that loves not his brother whom he has seen, how can he love God whom he has not seen?
21. And this commandment have we from him, That he that loves God love also his brother.
