1st John 4:21

15 Whoever will confess that Jesus is the Son of God, God remains in him, and he in God.

16 We know and have believed the love which God has in us. God is love, and he who remains in love remains in God, and God remains in him.

17 In this love has been made perfect with us, that we may have boldness in the day of judgment, because as he is, even so are we in this world.

18 There is no fear in love; but perfect love casts out fear, because fear has punishment. He who 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 who doesn`t love his brother whom he has seen, how can he love God whom he has not seen?

21 This commandment have we from him, that he who loves God should also love his brother.
