That too.
“The kingdom of the world has become the kingdom of our Lord and of his Christ, and he shall reign forever and ever.”
It's still a physical structure. And it still has to land on earth after the thousand years of Revelation 20. It's cloaked in orbit of earth. Not far away. Close enough that we could see it easily with the naked eye. And easier enough for it's inhabitants to look back down on us. When the time comes for it to bust out of it's cloak, I think it's this:
"Then God’s temple in heaven was opened, and the ark of his covenant was seen within his temple. There were flashes of lightning, rumblings, peals of thunder, an earthquake, and heavy hail.
People on earth are going to be able to look up and see it. When it comes down and lands on earth, we will be in it. It's been our Home for the previous thousand years. It has to land on earth for Judgement Day. All of the dead will then be raised on earth. This is the second resurrection. And the sea gave up the dead who were in it, Death and Hades gave up the dead who were in them, and they were judged, each one of them, according to what they had done. And the dead marched up over the broad plain of the earth and surrounded the camp of the saints and the beloved city. And they were judged, each one of them, according to what they had done.
Can you imagine the sight of this? This massive building, bright and shinny, stretching across the American continent, one side in Canada, the other in Mexico, and reaching up to the stratosphere. Scientists have said that it's too big to be a square, gravity would force it into a sphere. And all of the resurrected lost from all of time surrounding this Holy City. Through the open gates of pearl they can see the tree of life. Satan convinces them their only chance for survival at this point is to rush the gates, and get to the tree of life. Based on their sheer numbers, some think it doable.
"And they marched up over the broad plain of the earth and surrounded the camp of the saints and the beloved city, but fire came down from heaven and consumed them, and the devil who had deceived them was thrown into the lake of fire and sulfur where the beast and the false prophet were, and they will be tormented day and night forever and ever.
So it has to come down to earth for this to happen.
Peaceful Sabbath.
