1 John 3:3-9

And all who have this eager expectation will keep themselves pure, just as he is pure. Everyone who sins is breaking God’s law, for all sin is contrary to the law of God. And you know that Jesus came to take away our sins, and there is no sin in him. Anyone who continues to live in him will not sin. But anyone who keeps on sinning does not know him or understand who he is. Dear children, don’t let anyone deceive you about this: When people do what is right, it shows that they are righteous, even as Christ is righteous. 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. Those who have been born into God’s family do not make a practice of sinning, because God’s life is in them. So they can’t keep on sinning, because they are children of God.
