1 John 3:6-10

Whoever remains in Him does not sin. Whoever sins has not seen Him and does not know Him. Little children, let no one deceive you. The one who does righteousness is righteous, just as Christ is righteous. Whoever practices sin is of the devil, for the devil has been sinning from the beginning. For this purpose the Son of God was revealed, that He might destroy the works of the devil. Whoever has been born of God does not practice sin, for His seed remains in him. And he cannot keep on sinning, because he has been born of God. In this the children of God and the children of the devil are revealed: Whoever does not live in righteousness is not of God, nor is the one who does not love his brother.
