A great impediment is finding words to describe.
I'm not sure that God claims omnipotence with respect to a multiverse or the essential Logic that causes it to take various forms. The God of the bible claims near omnipotence over It's particular creation.
There must be a set of Principles that transcends our Creator.
Does it make any sense to say that someone created the Principle that 2+2 must equal 4 or that all circles must be round?
