1 John 3:9
Whoever is born of God does not commit sin; for his seed remains in him: and he cannot sin, because he is born of God.
He cannot sin any more than a good mother can kill her child. She might be able in a thousand ways to kill the child, but her heart would forbid it and make the impossibility absolute.
(J. B. Figgis, M. A.)
