THE EARTH WILL BE MUCH LARGER THAN IT CURRENTLY IS NOW

Got this off FB from a gal that is a great scriptorian:

Revelation 21:16 tells us the size of the New Jerusalem:

"And the city lieth foursquare, and the length is as large as the breadth: and he measured the city with the reed, twelve thousand furlongs. The length and the breadth and the height of it are equal."

One furlong is 220 yards, so 12,000 furlongs is 1500 miles. This is about the distance from Jackson County,  Missouri to Salt Lake City,  Utah.
John says the New Jerusalem will be this dimension high, wide, and long.
1500x1500x1500 is 3.375 BILLION cubic miles if John meant it would be a cube, or 1.77 billion cubic miles if it's a sphere (globe).

The earth itself is currently 260 billion cubic miles.

On a related note, I was reading through some Q and A between Joseph Fielding (asking) and Parley P. Pratt (answering), where Parley said that the earth in the Millennium will be "many times larger than it is now".

Ques. 7th.—How can the stars fall from heaven to earth, when they (as far as we know) are much larger than the earth?

Ans.—We are nowhere given to understand that all the stars will fall or even many of them: but only “as a fig tree casteth her untimely figs when she is shaken with a mighty wind.” The stars which will fall to the earth, are fragments, which have been broken off from the earth from time to time, in the mighty convulsions of nature. Some in the days of Enoch, some perhaps in the days of Peleg, some with the ten tribes, and some at the crucifixion of the Messiah. These all must be restored again at the “times of restitution of all things .” This will restore the ten tribes of Israel; and also bring again Zion, even Enoch’s city.

It will bring back the tree of life which is in the midst of the paradise of God; that you and I may partake of it. [See Rev. ii, 7-] When these fragments, (some of which are vastly larger than the present earth) are brought back and joined to this earth,it will cause a convulsion of all nature; the graves of the Saints will be opened, and they rise from the dead; while the mountains will flow down, the vallies rise, the sea retire to its own place, the islands and continents will be removed, and earth be rolled together as a scroll. The earth will be many times larger than it is now.—“If I have told you of earthly things and ye believe not; what would you think if you were to be told of heavenly things ?"
