But the one who hates 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 manifested: everyone who does not do righteousness is not of God, as well as the one who does not love his brother.
If someone says, “I love God,” and hates his brother, he is a liar; for the one who does not love his brother whom he has seen, cannot love God whom he has not seen.
