What question would you ask God?
I wouldn't.
It's God.
If God wanted me to know or understand something...then I know and understand it.
No questions necessary.
Asking God questions kinda implies God doesn't know what I would want to know and needs to be asked.
Otherwise God's keeping information from me for my own good, for God's own good, because God's capricious and arbitrary, or because God want's to keep information from me in order to cause fear and insecurity.
Either way, asking questions would ultimately be pointless.
I wouldn't understand the answer, I wouldn't get the answer I wanted just the information God wanted me to have, or be lied to for God's own purpose which may be to hurt me or cause me doubt and pain.
And if God lied to me? Or God didn't answer just made my curiosity feel sated? How could I ever prove God wrong?
God is not bound by my reasoning or logic. I am.
Of course that's all assuming God's omniscient and omnipotent.
If God's not...then we're all screwed as he's just some long lived guy with super powers.
If I believed in God, and in considering a concept of "God," I couldn't accept that.
So...I wouldn't ask God anything. I'd just trust God.
If you had a chance to meet God one-on- one
Then that would be proof of God's existence.
And that pretty much answers any question.
Any question that may come to mind would seem pointless in the face of being in the presence of God.
