Revelatory texts are used to affirm divine will and choosing; rational reasoning then explains why the attribute belongs to its subject and why originated states are not admitted as occurring in the divine essence.
The scriptural argument affirms the attribute, while the theological reasoning addresses its eternity and subsistence in God. These are complementary rather than interchangeable forms of argument.
A party may accept the word “will” while disagreeing about its reality. Verbal agreement therefore does not settle the substantive theological dispute.
