1 John 4:15-21 (NKJV)
15 Whoever confesses that Jesus is the Son of God, God abides 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 who abides in love abides in God, and God in him.
17 Love has been perfected among us in this: 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 involves torment. But he who fears has not been made perfect in love.
19 We love Him because He first loved us.
20 If someone says, “I love God,” and hates his brother, he is a liar; for he who does not love his brother whom he has seen, how can he love God whom he has not seen?
21 And this commandment we have from Him: that he who loves God must love his brother also.
