I made a thread a few weeks ago, on God's various depictions in fiction. This one, however, is about the logical conception of a deity or supreme being, under the working assumption that one exists in real life.
I think if God were to exist, then the following would necessarily be true of Him:
-He'd be a Deistic deity, given that he has not smitten any opposing religions to his own.
-He wouldn't exactly give much of a shit given that he seems to not intervene.
-He doesn't seem to change the laws of physics all that much, so he has to be a pretty decisive guy.
-Given that he has not intervened much (if at all) in human affairs in the last two millenia, he's obviously interested most in observing humanity, rather than in assisting humanity or perfection (as most major religions paint their deities).
Based on that, I'd conclude God (assuming he exists) is probably an INTJ 5w6 sp/so, |R|COEN.
