11 Dear friends, since God loved us that much, we surely ought to love each other. 12 No one has ever seen God. But if we love each other, God lives in us, and his love is brought to full expression in us.
20 If someone says, "I love God," but hates a fellow believer,4:20 Greek hates his brother. that person is a liar; for if we don’t love people we can see, how can we love God, whom we cannot see? 21 And he has given us this command: Those who love God must also love their fellow believers.4:21 Greek The one who loves God must also love his brother.
