It's a new earth and the New Jerusalem comes down from heaven on to earth so it is in effect a heavenly kind of earth. NOT THIS ONE
Yet the New heaven will still be away from the new Earth as the current heaven is. Eternity is spent on the new Earth rather than in heaven.
Heaven will remain where it is but eternity is spent upon the Earth and The Father and Son will be upon the Earth as well. That doesn't mean no one can go to heaven during the eternity but the primary home will be the Earth according to various scriptures. Rev 21-22 indicate this but there are other scriptures as well. Basically heaven is a temporary place for God and the angels and the spirits of the dead. Eventually all will inhabit the Earth.
1Ch_23:25 For David said, The LORD God of Israel hath given rest unto his people, that
they may dwell in Jerusalem for ever:
Rev_5:10 And hast made us unto our God kings and priests: and
we shall reign on the earth.
Psa_37:9 For evildoers shall be cut off: but those that wait upon the LORD,
they shall inherit the earth.
Psa_37:11 But
the meek shall inherit the earth; and shall delight themselves in the abundance of peace.
Psa_37:22
For such as be blessed of him shall inherit the earth; and they that be cursed of him shall be cut off.
Mat_5:5 Blessed are the meek: for
they shall inherit the earth.
Job_19:25 For I know that my redeemer liveth, and that
he shall stand at the latter day upon the earth:
Zec 14:16 And it shall come to pass, that every one that is left of all
the nations which came against Jerusalem shall even go up from year to year to worship the King, the LORD of hosts, and to keep the feast of tabernacles.
Zec 14:17 And it shall be, that whoso will not come up of all the families of the earth unto Jerusalem to worship
the King, the LORD of hosts, even upon them shall be no rain.
John 14:23 Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and
we will come unto him, and make our abode with him.
Rev 21:2 And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.
Rev 21:3 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.
Rev 21:10 And he carried me away in the spirit to a great and high mountain, and shewed me that great city, the holy Jerusalem, descending out of heaven from God,
Rev 21:11 Having the glory of God: and her light was like unto a stone most precious, even like a jasper stone, clear as crystal;
Rev 21:12 And had a wall great and high, and had twelve gates, and at the gates twelve angels, and names written thereon, which are the names of the twelve tribes of the children of Israel:
Rev 21:13 On the east three gates; on the north three gates; on the south three gates; and on the west three gates.
Rev 21:14 And the wall of the city had twelve foundations, and in them the names of the twelve apostles of the Lamb.
Rev 21:15 And he that talked with me had a golden reed to measure the city, and the gates thereof, and the wall thereof.
Rev 21:16 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.
Rev 21:17 And he measured the wall thereof, an hundred and forty and four cubits, according to the measure of a man, that is, of the angel.
Rev 21:18 And the building of the wall of it was of jasper: and the city was pure gold, like unto clear glass.
Rev 21:19 And the foundations of the wall of the city were garnished with all manner of precious stones. The first foundation was jasper; the second, sapphire; the third, a chalcedony; the fourth, an emerald;
Rev 21:20 The fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, a topaz; the tenth, a chrysoprasus; the eleventh, a jacinth; the twelfth, an amethyst.
Rev 21:21 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.
Rev 21:22 And I saw no temple therein: for
the Lord God Almighty and the Lamb are the temple of it.
It is not man who will go to heaven to dwell with the Father and Jesus in the eternity but the Father and Jesus dwelling with Man upon the new Earth!
Heaven is the temporary dwelling place for God, angels and the spirits of the dead saints. The eternal home for all is the new Earth.
