But the one hating his brother is in the darkness, and walks in the darkness, and does not know where he is going, because the darkness blinded his eyes.
By this the children of God and the children of the devil are made known: Everyone not practicing righteousness is not of God; also the one not loving his brother.
If anyone says, I love God, and hates his brother, he is a liar. For the one not loving his brother whom he has seen, how is he able to love God whom he has not seen?
