8 But when people keep on sinning, it shows that they belong to the devil, who has been sinning since the beginning. But the Son of God came to destroy the works of the devil. 9 Those who have been born into God’s family do not make a practice of sinning, because God’s life3:9 Greek because his seed. is in them. So they can’t keep on sinning, because they are children of God. 10 So now we can tell who are children of God and who are children of the devil. Anyone who does not live righteously and does not love other believers3:10 Greek does not love his brother. does not belong to God.
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.
