In the Old Testament Almighty G*D used a Jackass, Several Heathen Monarchs(Nebercanezer(sp/), Cyrus the Great, and Darius, don’t YOU think that Almighty G*D can used EVEN a Misguided MORMAM to do his work?
I won't say he can't...for Almighty G*D even has allowed Satan to operate at times to function in ways we don't readily admit...that's what the word "sovereign" implies...
The tendency, however, when you look thru the Old Testament is for God to not use open idolaters...
(Otherwise, who would get the "glory" for a great Mormon presidency...why the distinct Mormon gods, of course!)
