1a 2ae q19 a10: Whether it is necessary for the human will, in order to be good, to be conformed to the Divine will, as regards the thing willed? Yes.

Quicumque non conformat voluntatem suam voluntati divinae in volito, habet malam voluntatem, quia forma voluntatis est ex obiecto sicut et cuiuslibet actus; si ergo tenetur homo conformare voluntatem suam voluntati divinae, sequitur quod teneatur conformare in volito.

Whoever does not conform his will to the Divine will, as to the thing willed, has an evil will, because the will takes its form from the object, as does every act; if therefore man is bound to conform his will to the Divine will, it follows that he is bound to conform it, as to the thing willed.

Quod volitum divinum, secundum rationem communem, quale sit, scire possumus. Scimus enim quod Deus quidquid vult, vult sub ratione boni. Et ideo quicumque vult aliquid sub quacumque ratione boni, habet voluntatem conformem voluntati divinae, quantum ad rationem voliti. Sed in particulari nescimus quid Deus velit. Et quantum ad hoc, non tenemur conformare voluntatem nostram divinae voluntati.

We can know by a general formal aspect what God wills. For we know that whatever God wills, He wills it under the formal aspect of good. Consequently whoever wills a thing under any formal aspect of good, has a will conformed to the Divine will, as to the formal aspect of the thing willed. But we know not what God wills in particular. And in this respect we are not bound to conform our will to the Divine will.

In statu tamen gloriae, omnes videbunt in singulis quae volent, ordinem eorum ad id quod Deus circa hoc vult. Et ideo non solum formaliter, sed materialiter in omnibus suam voluntatem Deo conformabunt.

But in the state of glory, every one will see in each thing that he wills, the relation of that thing to what God wills in that particular matter. Consequently he will conform his will to God in all things not only formally, but also materially.
