1 John 3:8-10

8 Those who do what is sinful belong to the devil. They are just like him. He has been sinning from the beginning. But the Son of God came to destroy the devil's work.

9 Those who are born again because of what God has done will not keep on sinning. God's very nature remains in them. They can't go on sinning. They have been born again because of what God has done.

10 Here is how you can tell the difference between the children of God and the children of the devil. Those who don't do what is right do not belong to God. Those who don't love their brothers and sisters do not belong to him either.
