1 John 4:19-21

19 We have the power of loving, because he first had love for us.

20 If a man says, I have love for God, and has hate for his brother, his words are false: for how is the man who has no love for his brother whom he has seen, able to have love for God whom he has not seen?

21 And this is the word which we have from him, that he who has love for God is to have the same love for his brother.
