But he who hates his brother is in the darkness, and walks in the darkness, and doesn’t know where he is going, because the darkness has blinded his eyes.
In this the children of God are revealed, and the children of the devil. Whoever doesn’t do righteousness is not of God, neither is he who doesn’t love his brother.
If a man says, “I love God,” and hates his brother, he is a liar; for he who doesn’t love his brother whom he has seen, how can he love God whom he has not seen?
