Martin Luther, The Bondage of the Will, Revell, 1957, p. 102.
Man…does not do evil against his will, under pressure, as though he were taken by the scruff of the neck and dragged into it, like a thief…being dragged off against his will to punishment; but he does it spontaneously and voluntarily. And this willingness or volition is something which he cannot in his own strength eliminate, restrain or alter.
