1 John 4:20 ASV

¹⁸  There is no fear in love: but perfect love casteth out fear, because fear hath punishment; and he that feareth is not made perfect in love.

¹⁹  We love, because he first loved us.

²⁰  If a man say, I love God, and hateth his brother, he is a liar: for he that loveth not his brother whom he hath seen, cannot love God whom he hath not seen.

²¹  And this commandment have we from him, that he who loveth God love his brother also.
