13. Brothers, do not be surprised when the people of this world hate you.
14. We know that we have left death and have come into life. We know this because we love our brothers in Christ. Whoever does not love is still in death.
15. Everyone who hates his brother is a murderer. And you know that no murderer has eternal life in him.
16. This is how we know what real love is: Jesus gave his life for us. So we should give our lives for our brothers.
17. Suppose a believer is rich enough to have all that he needs. He sees his brother in Christ who is poor and does not have what he needs. What if the believer does not help the poor brother? Then the believer does not have God’s love in his heart.
