The Bondage of the Will

But whoever wishes to understand these things let him think thus: — that God works evil in us, that is, by us, not from the fault of God, but from the fault of evil in us: — that is, as we are evil by nature, God, who is truly good, carrying us along by His own action, according to the nature of His Omnipotence, cannot do otherwise than do evil by us, as instruments, though He Himself be good; though by His wisdom, He overrules that evil well, to His own glory and to our salvation.

Thus God, finding the will of Satan evil, not creating it so, but leaving it while Satan sinningly commits the evil, carries it along by His working, and moves it which way He will; though that will ceases not to be evil by this motion of God.

In this same way also David spoke concerning Shimei. "Let him curse, for God hath bidden him to curse David." (2 Samuel xvi. 10). How could God bid to curse, an action so evil and virulent! There was no where an external precept to that effect. David, therefore, looks to this: — the Omnipotent God saith and it is done: that is, He does all things by His external word. Wherefore, here, the divine action and omnipotence, the good God Himself, carries along the will of Shimei, already evil together with all his members, and before incensed against David, and, while David is thus opportunely situated and deserving such blasphemy, commands the blasphemy, (that is, by his word which is his act, that is, the motion of his action), by this evil and blaspheming instrument.
