1 John 3:14-16

14We know that we now have new life with God. Death no longer has power over us. We know this because we love our Christian friends. But anyone who does not love other believers is still under the power of death.

15Anyone who hates other believers is like someone who murders other people. You know that a person like that does not have true life with God.

16This is how we know what true love is: Jesus Christ gave his own life on the cross. He died on our behalf. So we too ought to give our lives for other believers.
