1 John 3:14-16

14If we love our brothers and sisters who are believers, it proves that we have passed from death to life. But a person who has no love is still dead.

15Anyone who hates another brother or sister is really a murderer at heart. And you know that murderers don’t have eternal life within them.

16We know what real love is because Jesus gave up his life for us. So we also ought to give up our lives for our brothers and sisters.
