If a place, Hell, is really existent and God can't be found there, it would prove God is not:
Omnipresent (can't be everywhere if there is a place God is not)
Omnipotent (can't be all power if there is a place God can't go)*
Omniscient (can't be all knowing if there is a place God's knowledge can't reach)

* If God has the power to enter Hell but does not, then the omni-benevolence of God is negated, as God is deliberately ignoring some of God's creatures.
