3 See how very much our Father loves us, for he calls us his children, and that is what we are! But the people who belong to this world don’t recognize that we are God’s children because they don’t know him.

Love One Another

¹¹ This is the message you have heard from the beginning: We should love one another. ¹² We must not be like Cain, who belonged to the evil one and killed his brother. And why did he kill him? Because Cain had been doing what was evil, and his brother had been doing what was righteous. ¹³ So don’t be surprised, dear brothers and sisters,^[a] if the world hates you.

¹⁴ If we love our brothers and sisters who are believers,^[b] it proves that we have passed from death to life. But a person who has no love is still dead. ¹⁵ Anyone who hates another brother or sister^[c] is really a murderer at heart. And you know that murderers don’t have eternal life within them.

¹⁶ We 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. ¹⁷ If someone has enough money to live well and sees a brother or sister^[d] in need but shows no compassion—how can God’s love be in that person?

¹⁸ Dear children, let’s not merely say that we love each other; let us show the truth by our actions.
