If the new birth from God were perfect, sin would be morally impossible οὐ δύναται ἁμαρτεῖν . The new principle of life abides and grows in him, and, under perfect conditions, it entirely prevents the old unregenerate nature from rebelling. Note that St. John does not say οὐ δύναται ἁμαρτεῖν , " cannot commit a sin," but οὐ δύναται ἁμαρτάνειν , "cannot be a sinner." An act is different from a state of sin.
