11. Beloved, if God so loved us, we ought also to love one another.
12. No man has seen God at any time. If we love one another, God dwells in us, and his love is perfected in us.
13. By this we know that we dwell in him, and he in us, because he has given us of his Spirit.
14. And we have seen and do testify that the Father sent the Son to be the Savior of the world.
15. Whosoever shall confess that Jesus is the Son of God, God dwells in him, and he in God.
16. And we have known and believed the love that God has for us. God is love; and he that dwells in love dwells in God, and God in him.
17. In this is our love made perfect, that we may have boldness in the day of judgment: because as he is, so are we in this world.
18. There is no fear in love; but perfect love casts out fear: because fear has to do with punishment. He that fears is not made perfect in love.
19. We love him, because he first loved us.
20. If a man says, I love God, and hates 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 who loves God love his brother also.
