1 John 4:20
King James Version
“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, how can he love God whom he hath not seen?”
Context
17Herein is our love made perfect, that we may have boldness in the day of judgment: because as he is, so are we in this world.
18There is no fear in love; but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love.
19We love him, because he first loved us.
20If 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, how can he love God whom he hath not seen?
21And this commandment have we from him, That he who loveth God love his brother also.
