Some considerations that many people have not given thought to:
The intermediate Heaven, becomes the “New Heaven” on Earth when it is “coming down with God” and placed upon the “new Earth”. No longer, will God and all the inhabitants of Heaven, reside in a place, separate from the world and men. The completed kingdom and all its splendor, will be moved to Earth, where God and Christ shall reign, with all those who have joined them. Another noteworthy mention? Look at the later scripture, in verse 24; it says that the kings of the earth DO bring their glory and honour into it. Quite enlightening, is the mixture of KJV+Strong’s, when we look at the original context here: http://biblehub.com/kjvs/revelation/21.htm
1 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.
2 And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.
3 And I heard a great voice out of heaven saying, Behold, the tabernacle of God [is] with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, [and be] their God.
4 And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.
21 And the twelve gates [were] twelve pearls; every several gate was of one pearl: and the street of the city [was] pure gold, as it were transparent glass.
22 And I saw no temple therein: for the Lord God Almighty and the Lamb are the temple of it.
23 And the city had no need of the sun, neither of the moon, to shine in it: for the glory of God did lighten it, and the Lamb [is] the light thereof.
24 And the nations of them which are saved shall walk in the light of it: and the kings of the earth do bring their glory and honour into it.
25 And the gates of it shall not be shut at all by day: for there shall be no night there.
