Hi Gater 76! I'm not really "on" this forum anymore, but they notified me and you asked me directly, so want to answer you. The question is answered completely on one of my two prophecy sites,
www.homestead.com/PROPHECYCENTER/prophecycenter.html or
www.geocities.com/leecin82007/PROPHECY_CENTER.html and I will give brief response here. At the end of great tribulation, God's wrath, day of the Lord, Jacob's trouble, etc, at second coming you will notice in Jude 14, Zech 14:5 and the Book of Revelation that the Raptured saints and the dead in Christ, incl. recent martyrs who did not take the mark of the beast, will come back behind Jesus on white horses and watch Jesus defeat all who turn on him at the Megiddo gathering, and cast the devil (and Antichrist, false prophet) alive into hell. There will also be a Jewish tiny remnant of elect, gathered alive and in terrestrial bodies to reproduce- the Bible indicates they will then be given bodies like Adam and Eve had, so they and their children for the next 1000 years will be the ones who encounter the release of Satan at the end and the children will be put through their test!- but you asked about the ones in celestrial bodies, the ones who won't be repoducing!- there is good speculation that heaven will be brought down to hover over Jerusalem for 1000 years, until the new heaven, new earth and new Jerusalem (see the Book of Revelation) are created at the end and that the Raptured and dead in Christ who returned with Jesus can travel back and forth to the mansions or dwelling places Jesus is building for us now (see John 14:1-6) and we know that we won't be separated from Jesus, so even if heaven isn't brought down, I figure we will be able to travel through space. Yes, indications are that we will be with those in natural bodies on earth, too, along with angels. I haven't really researched this whole thing lately, and I am OFF OF Christian forums Prophecy section for the most part- too much arguing, too many preterists, etc.,- but you had an honest question for me. I will probably not answer any more, because anyone who wants to know my stand can find it on my websites. Thanks!!---Places of Refuge
