15 Whoever confesses that Jesus is the Son of God, God abides in him, and he in God. 16 So we know and believe the love God has for us. God is love, and he who abides in love abides in God, and God abides in him. 17 In this is love perfected with us, that we may have confidence for 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. For fear has to do with punishment, and he who fears is not perfected in love. 19 We love, because he first loved us. 20 If any one says, “I love God,” and hates his brother, he is a liar; for he who does not love his brother whom he has seen, cannot* love God whom he has not seen.
