18 There is no fear in love; but perfect love casts out fear, because fear involves punishment, and the one who fears is not perfected in love.
19 We love, because He first loved us.
20 If someone says, "I love God," and hates his brother, he is a liar; for the one who does not love his brother whom he has seen, cannot love God whom he has not seen.
21 And this commandment we have from Him, that the one who loves God should love his brother also.
