I'm not so much arguing that God can't "make a decision", as that the idea of "making a decision" is meaningless (or at the very least unworthy of the connotations we give it) when an omniscient POV is involved. If we treat God as a program, for rhetorical purposes, an input of "worship" has an output of "salvation"; no notion of choice is required.

A conscious being is one who maps reality to an internal active symbology, and "experiences" an output. No particular ability is required.
