1 John 4:19-21

19We are able to love God and other people because God loved us first.

20Someone may say, ‘I love God.’ But if he says that and he hates another Christian, he is telling a lie. He sees other believers but he does not love them. So he surely cannot love God that he has not seen.

21This is the command that God has given us. He has told us that anyone who loves him should love other Christians too.
