Nathan, Nathan, Nathan. Docetism again? 1Corinthians 15 says that flesh will be changed from something corruptible into something incorruptible. It doesn't say that flesh and blood will be done away with. All of the corruption will simply be removed from it. Elsewhere it talks about death being swallowed or engulfed by life.
There's between 10 and 26 demensions right now, depending on whose version of Superstring Theory that you think has the best evidence and the most solid mathematical data behind it. Hmmm....simplifying this....
The UK has a Sci-Fi television series that I believe also airs on the Sci-Fi channel on US cable networks called "Doctor Who." In Doctor Who the main character, the Doctor, is an extraterrestrial that has a time machine, (that can also travel to other planets,) that's quite a bit bigger on the inside than it is on the outside.
There's no reason to believe that the extrademensionality spoken of in Ephesians 3 and various other passages of Scripture won't be literally manifested on the earth, perhaps as early as prior to the millenium as passages like Isaiah 11 and other passages that take place prior to the millenium indicate to me.
As this resurrection world is coming about that's expected by both the prophecies of the Scriptures and the Omega Point Theory in science, all of the indications are there that we can have absolutely every life form that has ever existed living on the planet at that time without things being cramped. God always creates abundance when He's doing something, so there's no reason to believe that that would be a waste if all wouldn't yet be living on the planet at that time because of the LOF detour that some people (about a third of the planet in Revelation if I remember correctly {Rev 9:18}), angels, and some animals will have to endure.
Extrademensionality in Scripture doesn't mean that flesh will be done away with, any more than your building an extra room onto your house implies that you burned down the rest of the house. Since all areas of breath, being, and demensionality come from God, and since blood is hallowed in Scripture, and flesh is to be sanctified in Scripture, if God were seeking to destroy flesh and blood, then His house couldn't stand 'cause it would be a house divided against itself. Romans 6 says that through Christ Jesus we present ourselves to God as alive from the dead and our bodily parts as instruments of righteousness. Romans 12 says it's to be a living sacrifice rather than either a dead one or an annihilated one by resurrection.
If our flesh and blood are done away with, then a very large part of the redemptive work of Christ was in vain because He died as much for the body as for the soul and spirit. He's the ransom for our bodies as well as for our spirits and souls. Otherwise, the resurrection was pointless and the sacrifice was not only unneccessarily brutal, but it would have sufficed without the resurrection from the dead if it was only to be the freeing of our spirits and souls from their death in trespasses.
. . .there won't be flesh as we know it . . .
20 For His invisible attributes are descried from the creation of the world, being apprehended by His achievements, besides His imperceptible power and divinity, for them to be defenseless, (Romans 1:20 Concorant Literal)
20 since the invisible things of Him, even His unknown power and Deity, are clearly seen from the creation of the world, being understood by the things which are made; so that they are inexcuseable: (Romans 1:20 Scarlett's New Testament 1798)
I think that where people get easily confused is the fact that in the resurrection there won't be any marrying or giving in marriage, and people don't often think about "what about after the resurrection in the all in all world??" The abdication of Christ in 1Corinthians 15:24,28 is the restoration of the Edenic state where we'll definitely be told to be fruitful and multiply once again. 2Timothy 2 says that when you're engaged in warfare, you're not entangling yourself in the affairs of life, which to me would indicate that the Gospel dispensation related to the resurrecting world is one of ongoing spiritual warfare, but where the righteous obviously and universally have the upper-hand.
As there's neither pardon in this age nor in the one to come for blasphemers of the Holy Spirit, but we often ask people to consider ages after that, I'm saying the same thing about the resurrection age where there's no marriage. What about after that? All of the indications of Scripture are a total restoration of spirit, soul, and body for all of Creation and there's Scriptures that speak in terms of an
"ever-increasing" Kingdom which isn't successfully answered by merely considering the possibility of extraterrestrial and extrademensional life forms in parallel worlds. Yes, we've had multiplication in this eon in order to resolve the issue of wickedness in a familial context, but there are more issues of righteousness that have to be resolved by multiplication -- and that'll never end. God is a baby-aholic. While the earth remains, seedtime and harvest will not cease, according to Genesis 8:22. There's only no "day and night" in New Jerusalem, which to me indicates it being on the North Pole or something approximating the geography of that at the time. At least with the current laws of the earth, only one of the poles could sustain an indefinitely long day or night. (not related, but an interesting link:

Suppose we not only had elevated cities on the earth like in the Star Wars movies or in the Jetsons cartoons, but subterranean cities like in some of the folklore? The only limitations would be waste management, food production, some measure of recycling, and renewable resources in that kind of environment. Sky scrapers could easily be turned into farms with each floor growing a different crop. Wouldn't be hard to do that within 50 years to be perfectly honest. How much more in an environment where the Holy Spirit is perpetually intensely on all flesh??
