Two radically different things are both called “will”. One is a definite orientation and effort toward this end rather than that, analogous to a kind of desire. The other is supposed to be a power of decision independent of deliberation.
I don’t believe that there is or could be such a thing as decision with absolutely no deliberation. What we have is an ability to deliberate, and to choose between alternatives based on that deliberation (see also What We Really Want). Neither deliberation nor decision could apply to an eternal being, because these necessarily involve time and change.
