13. My friends, don't be surprised if the people of this world hate you.
14. Our love for each other proves that we have gone from death to life. But if you don't love each other, you are still under the power of death.
15. If you hate each other, you are murderers, and we know that murderers do not have eternal life.
16. We know what love is because Jesus gave his life for us. That's why we must give our lives for each other.
17. If we have all we need and see one of our own people in need, we must have pity on that person, or else we cannot say we love God.
