13 So do not be surprised, my brothers and sisters, if the people of the world hate you.
14 We know that we have left death and come over into life; we know it because we love our brothers and sisters. Whoever does not love is still under the power of death.
15 All who hate others are murderers, and you know that murderers have not got eternal life in them.
16 This is how we know what love is: Christ gave his life for us. We too, then, ought to give our lives for our brothers and sisters!
17 Rich people who see a brother or sister in need, yet close their hearts against them, cannot claim that they love God.
18 My children, our love should not be just words and talk; it must be true love, which shows itself in action.
19 This, then, is how we will know that we belong to the truth; this is how we will be confident in God's presence.
