Mans: Although discussion about pantheism takes us out from the main topic, it brings up the question of whether each of the elements and things in nature is a part of God? Do pantheists believe this?
Not far from the main topic.... The panthesis is that God is omnipresent, so everything would be immanent in Him. However, the explicit meaning of that statement would depend on one's definition of "God." For example, if He is defined as Consciousness or Intelligence than It would be immanent in material reality, i.e., Consciousness/Intelligence would be manifest in it, but if not equally so, we would have the material polarities of conscious/unconscious, good/evil, etc.
If God was both Omnipresent and Omniscient, such polarities would not manifest, because they reflect a lack of consciousness or awareness of wholeness. Either way, the idea of omnipotence can be dispensed with.
