Whether the will is moved of necessity by the exterior mover which is God?

Objections

Objection 1 : It would seem that the will is moved of necessity by God. For every agent that cannot be resisted moves of necessity. But God cannot be resisted, because His power is infinite; wherefore it is written (Rm. 9:19): "Who resisteth His will?" Therefore God moves the will of necessity.
Objection 2 : Further, the will is moved of necessity to whatever it wills naturally, as stated above (Article [2], ad 3). But "whatever God does in a thing is natural to it," as Augustine says (Contra Faust. xxvi, 3). Therefore the will wills of necessity everything to which God moves it.
Objection 3 : Further, a thing is possible, if nothing impossible follows from its being supposed. But something impossible follows from the supposition that the will does not will that to which God moves it: because in that case God's operation would be ineffectual. Therefore it is not possible for the will not to will that to which God moves it. Therefore it wills it of necessity.
