“It is the fault, therefore, of the instruments, which God does not allow to be idle, that evil things are done, with God himself setting them in motion. It is just as if a carpenter were cutting badly with a chipped and jagged ax. Hence it comes about that the ungodly man cannot but continually err and sin, because he is caught up in the movement of divine power and not allowed to be idle, but wills, desires, and acts according to the kind of person he himself is.
“All this is settled and certain if we believe that God is omnipotent and also that the ungodly is a creature of God, although as one averse from God and left to himself without the Spirit of God, he cannot will or do good. The omnipotence of God makes it impossible for the ungodly to evade the motion and action of God, for he is necessarily subject to it and obeys it. But his corruption or aversion from God makes it impossible for him to be moved and carried along with good effect. God cannot lay aside his omnipotence on account of man’s aversion, and ungodly man cannot alter his aversion. It thus comes about that man perpetually and necessarily sins and errs until he is put right by the Spirit of God” (“The Bondage of the Will”, LW 33, pgs 176-177).
