1 John 3:3–10
3And everyone who thus hopes in him purifies himself as he is pure. 4Everyone who makes a practice of sinning also practices lawlessness; sin is lawlessness. 5You know that he appeared in order to take away sins, and in him there is no sin. 6No one who abides in him keeps on sinning; no one who keeps on sinning has either seen him or known him. 7Little children, let no one deceive you. Whoever practices righteousness is righteous, as he is righteous. 8Whoever makes a practice of sinning is of the devil, for the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the works of the devil. 9No one born of God makes a practice of sinning, for God’s seed abides in him; and he cannot keep on sinning, because he has been born of God. 10By this it is evident who are the children of God, and who are the children of the devil: whoever does not practice righteousness is not of God, nor is the one who does not love his brother.
