9-10People conceived and brought into life by God don't make a practice of sin. How could they? God's seed is deep within them, making them who they are. It's not in the nature of the God-begotten to practice and parade sin. Here's how you tell the difference between God's children and the Devil's children: The one who won't practice righteous ways isn't from God, nor is the one who won't love brother or sister. A simple test.
11For this is the original message we heard: We should love each other.
12-13We must not be like Cain, who joined the Evil One and then killed his brother. And why did he kill him? Because he was deep in the practice of evil, while the acts of his brother were righteous. So don't be surprised, friends, when the world hates you. This has been going on a long time.
14-15The way we know we've been transferred from death to life is that we love our brothers and sisters. Anyone who doesn't love is as good as dead. Anyone who hates a brother or sister is a murderer, and you know very well that eternal life and murder don't go together.
16-17This is how we've come to understand and experience love: Christ sacrificed his life for us. This is why we ought to live sacrificially for our fellow believers, and not just be out for ourselves. If you see some brother or sister in need and have the means to do something about it but turn a cold shoulder and do nothing, what happens to God's love? It disappears. And you made it disappear.
