1 John 4:19-21New International Version - UK (NIVUK)
19 We love because he first loved us. 20 Whoever claims to love God yet hates a brother or sister is a liar. For whoever does not love their brother and sister, whom they have seen, cannot love God, whom they have not seen. 21 And he has given us this command: anyone who loves God must also love their brother and sister.
