Reply Obj. 1: This gloss speaks of good as in the estimation of God, Who considers principally the intention of the end. Wherefore another gloss says on the same passage that "the treasure of the heart is the intention, according to which God judges our works." For the goodness of the intention, as stated above, redounds, so to speak, upon the goodness of the will, which makes even the external act to be meritorious in God's sight.
Reply Obj. 2: The goodness of the intention is not the whole cause of a good will. Hence the argument does not prove.
Reply Obj. 3: The mere malice of the intention suffices to make the will evil: and therefore too, the will is as evil as the intention is evil. But the same reasoning does not apply to goodness, as stated above (ad 2). ________________________
NINTH ARTICLE [I-II, Q. 19, Art. 9]
Whether the Goodness of the Will Depends on Its Conformity to the
Divine Will?
Objection 1: It would seem that the goodness of the human will does not depend on its conformity to the Divine will. Because it is impossible for man's will to be conformed to the Divine will; as appears from the word of Isa. 55:9: "As the heavens are exalted above the earth, so are My ways exalted above your ways, and My thoughts above your thoughts." If therefore goodness of the will depended on its conformity to the Divine will, it would follow that it is impossible for man's will to be good. Which is inadmissible.
Obj. 2: Further, just as our wills arise from the Divine will, so does our knowledge flow from the Divine knowledge. But our knowledge does not require to be conformed to God's knowledge; since God knows many things that we know not. Therefore there is no need for our will to be conformed to the Divine will.
Obj. 3: Further, the will is a principle of action. But our action cannot be conformed to God's. Therefore neither can our will be conformed to His.
On the contrary, It is written (Matt. 26:39): "Not as I will, but as Thou wilt": which words He said, because "He wishes man to be upright and to tend to God," as Augustine expounds in the Enchiridion [*Enarr. in Ps. 32, serm. i.]. But the rectitude of the will is its goodness. Therefore the goodness of the will depends on its conformity to the Divine will.
I answer that, As stated above (A. 7), the goodness of the will depends on the intention of the end. Now the last end of the human will is the Sovereign Good, namely, God, as stated above (Q. 1, A. 8; Q. 3, A. 1). Therefore the goodness of the human will requires it to be ordained to the Sovereign Good, that is, to God.
