In the near future I am likely to have to GM God. Part of the difficulty I perceive I am going to have in this is God is immeasurably smarter, wiser, more creative, etc than I am - not by a quantifiable degree, but entirely on a different order. Ordinarily when I GM characters that are better than me in some mental/spiritual area, I cheat by using a certain amount of extra time to figure out what that character would do/think/feel either before a game session or during it. Because the difference here is functionally infinite, however, that method won't work. What should I do instead?
I have read How can I roleplay a character more manipulative than myself? and How do I roleplay a character more intelligent than I am? but both of these seem heavily tailored to players, rather than GMs. The top-rated answer (by @AceCalhoon) on the latter question at least theoretically addresses the GM side of the problem, but I'd prefer an answer that specifically focused on GMing and was vetted by the community on that point alone.
