1 John 4:20

20 If anyone says, "I love God," and hates his brother, he is a liar. For if a person does not love his brother, whom he has seen, then he cannot love God, whom he has not seen.

1 John 4:20 In-Context

18 There is no fear in love. On the contrary, love that has achieved its goal gets rid of fear, because fear has to do with punishment; the person who keeps fearing has not been brought to maturity in regard to love.
19 We ourselves love now because he loved us first.
20 If anyone says, "I love God," and hates his brother, he is a liar. For if a person does not love his brother, whom he has seen, then he cannot love God, whom he has not seen.
21 Yes, this is the command we have from him: whoever loves God must love his brother too.
