The "beloved city"
Rev 21:1 has to mean that the earth will be changed. For example: "and there was no more sea." If Rev 21:1 actually meant that the original earth was completely destroyed; that is, no longer existed; that would mean that Eccl 1:4 was wrong. Since the word of God does not contradict itself, that must mean that Rev 21:1 means that the earth will be completely *changed* or be completely renovated.
As to "the beloved city":
20 Though Noah, Daniel, and Job, were in it, as I live, saith the Lord GOD, they shall deliver neither son nor daughter; they shall but deliver their own souls by their righteousness.
21 For thus saith the Lord GOD; How much more when I send my four sore judgments upon Jerusalem, the sword, and the famine, and the noisome beast, and the pestilence, to cut off from it man and beast?
22 Yet, behold, therein shall be left a remnant that shall be brought forth, both sons and daughters: behold, they shall come forth unto you, and ye shall see their way and their doings: and ye shall be comforted concerning the evil that I have brought upon Jerusalem, even concerning all that I have brought upon it.
Ezek 14:20-22 (KJV)
And this:
2 Son of man, set thy face toward Jerusalem, and drop thy word toward the holy places, and prophesy against the land of Israel,
3 And say to the land of Israel, Thus saith the LORD; Behold, I am against thee, and will draw forth my sword out of his sheath, and will cut off from thee the righteous and the wicked.
4 Seeing then that I will cut off from thee the righteous and the wicked, therefore shall my sword go forth out of his sheath against all flesh from the south to the north:
5 That all flesh may know that I the LORD have drawn forth my sword out of his sheath: it shall not return any more.
Ezek 21:2-5 (KJV)
And this, which is obviously an end-times prophecy:
20 And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh.
21 Then let them which are in Judaea flee to the mountains; and let them which are in the midst of it depart out; and let not them that are in the countries enter thereinto.
22 For these be the days of vengeance, that all things which are written may be fulfilled.
23 But woe unto them that are with child, and to them that give suck, in those days! for there shall be great distress in the land, and wrath upon this people.
24 And they shall fall by the edge of the sword, and shall be led away captive into all nations: and Jerusalem shall be trodden down of the Gentiles, until the times of the Gentiles be fulfilled.
25 And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring;
26 Men's hearts failing them for fear, and for looking after those things which are coming on the earth: for the powers of heaven shall be shaken.
27 And then shall they see the Son of man coming in a cloud with power and great glory.
Luke 21:20-27 (KJV)
