But he who hates his brother is in the darkness and walks in the darkness, and does not know where he is going, because the darkness has blinded his eyes.
By this it may be seen who are the children of God, and who are the children of the devil: whoever does not do right is not of God, nor he who does not love his brother.
If any one says, “I love God,” and hates his brother, he is a liar; for he who does not love his brother whom he has seen, cannot love God whom he has not seen.
