What you guys are talking about is the nature of God, and there are many things in this thread that are stated as facts that no one could possibly know. The scriptures say that God made man in His image. So why would God need hands, feet, arms, nose, legs and mouth? We're made to accommodate a terrestrial existence. We stand upright, we walk, talk, eat and speak. The scripture that says God is a spirit was a later addition and wasn't in the earliest texts, so His composition remains a bit of a mystery. Spirits can, however, appear as solid as you or me.
My own personal belief is that Jehovah was a spirit in the Old Testament days. But I believe Jehovah was the premortal Jesus. Thus, when Moses, Joshua and the seventy elders of Israel saw Him, He appeared as a flesh and bone being. The thing is, to be perfected Jehovah had to take upon Himself a physical body, die (which is a separation of body and spirit), then be eternally resurrected, which is a reunion of body and spirit. Those who say He was a spirit who "materialized" a body, and as some JWs have said, His real body was taken away perhaps to be displayed during the Millennium. But when Jesus appeared to his apostles, He invited them to "handle me and see" for "a spirit hath not flesh and bones as ye see me have." (Luke 24:38) Later, some 500 of the brethren saw the risen Lord, and He was not a spirit. (See 1 Cor. 15:6)
God being omnipresent is a myth. Although a sparrow cannot fall to the ground without Him noticing, He isn't everywhere present. God's presence can be felt in many places at once through the administration of the Holy Spirit. Finally, the scriptures tell us that Jesus is in the "express image" of the Father. If Jesus is therefore perfected with a physical body, why not also the Father?
We also shouldn't put limitations on anything. In a college theology course, my professor quoted from an ancient extra-biblical document. I don't remember where it came from or who allegedly wrote it, but the writer wrote something that I've never forgotten and which I think is profound. He said, essentially, "Everything is a system in the midst of like systems." It was a brilliant observation. A solar system is a system in the midst of like systems. So are galaxies. It's the same thing for microsystems no matter how sensitive our microscopes. So whether microscopes or telescopes, the statement appears to be a truism. My point is this: If the Universe is a system in the midst of like systems, what would prevent there being other universes beyond ours? And other dominions? Clement of Alexandria, who was an expert in First Century Christianity writes that those saints who are exalted "will be enthroned along with the other gods, who are set first in order under the Savior."
And Origen, another early church father, wrote: "Now it is possible that some may dislike what we have said representing the Father as the one true God, but admitting other beings besides the true God, who have become gods by having a share of God. They may fear that the glory of Him who surpasses all creation may be lowered to the level of those other beings called gods. ... [However], as, then there are many gods, but to us there is but one God the Father, and many Lords, but to us there is one Lord, Jesus Christ (cf. 1 Cor. 8:5-6). Although this may sound blasphemous on its face, Irenaeus (115-202) recognizes that the saints become joint heirs with Christ, which means that they, too, like Christ, inherit all that the Father has. He explains: "We were not made gods at our beginning, but first we were made men, then, in the end, gods." Thus, when Adam partook of the forbidden fruit, God (Eloheim, plural) said, "Behold, man has become as one of us."
The Jehovah's Witnesses have long thought they would be happy with a static existence on a Paradise Earth. Hiking, painting, learning to play musical instruments and having family reunions forever, worlds without end, is all they hope for. I remember when I went to school in Hawaii. At first I thought I'd really hit the jackpot. Swimming, diving, lying on the sand and enjoying the breeze while watching surfers. Blue skies, white fluffy clouds and mountains green with vegetation. It was great...for a few months. In that time I drove around the island of Oahu numerous times; I dove at Hunama Bay, did some snorkling at Shark's Cove and stuffed myself at the Polynesian Cultural Center, which had one of the greatest buffets I've ever seen (a friend got me in). But after those few months, I noticed two things: 1) I'd had enough of Paradise and its wonders. I wanted to go back to the mainland. And 2) the natives who'd grown up there were desperate to leave and go to the mainland.
How long would it take for the "great crowd" to tire of their Paradise Earth? Are they, as children of God, satisfied with the prospect of being little more than pets, taking no part in the running of the Universe?
Bottom line: God is not a giant. He's not omnipresent, though he is omnipotent and omniscient. How universes are brought into existence is beyond me, but it's known to God. And man can be a player in the creative process once he is resurrected and becomes an exalted being of incalcuable power and glory. He'll never supplant God, but they can act as gods and heirs. And that's worth living for.
