7 Children, don't be fooled. Anyone who does right is good, just like Christ himself.
8 Anyone who keeps on sinning belongs to the devil. He has sinned from the beginning, but the Son of God came to destroy all that he has done.
9 God's children cannot keep on being sinful. His life-giving power lives in them and makes them his children, so that they cannot keep on sinning.
10 You can tell God's children from the devil's children, because those who belong to the devil refuse to do right or to love each other.
11 From the beginning you were told that we must love each other.
12 Don't be like Cain, who belonged to the devil and murdered his own brother. Why did he murder him? He did it because his brother was good, and he was evil.
13 My friends, don't be surprised if the people of this world hate you.
