One thing god can’t know is the decisions that we will make with our free will. If he knew them, then we would just be robots executing a predefined script, we would have no responsability, god designed the script that way and we simply execute it.
If he doesn’t know our decisions and free will, then god can’t see into the future, he can’t completely understand our free will. He would be a god with some physical limitations. So did god design the universe with himself having some limitations ? An unlimited god can self limit himself ? That also means that there are items, elements of physical reality upon which he has no control. That is, he is within a larger universe having laws of physics which he can’t control. So then he could easily be a subgod, with a higher god above him. And there could be a heirarchy of gods, physical unverses, laws of physics etc. Maybe an infinte number. So then god could simply be an advanced alien with great powers and the god to our little corner of universe.
Then WHAT ARE THE ULTIMATE LAWS OF PHYSICS WHICH EVEN GOD MUST OBEY ?
This may be the only way to save religion from all of its contradictions. If we consider god to be a minor god with some limitations, then many contradictions disappear and the bible becomes OK. So he creates the world but has some limits on what he can do and see and on free will. He has to follow quirk rules like sacrificing his only son for our sins. But these rules were made by his god or some laws of physics upon which he has no control.
Maybe heaven and hell are created by some higher laws of physics and he sent down the prophets to warn us. In other words, if we consider god having less stringent requirements, well then maybe religion can make some sense after all. Now to create such a theory will be major achievment. Maybe some muslims or christians can start a theory of trans-physics and the structure of god.
