KJV1611, this heaven and earth is not the new heaven and earth spoken of in Rev 21.
According to 2 Peter 3, this heaven and earth will melt with fervent heat and we look for new heavens and new earth:
2 Peter 3:
10 But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
11 Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness,
12 Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?
13 Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.
And while I understand that all born again believers have the arrabōn ... the earnest of the Spirit, this earnest of the Sprit is held in a tabernacle in which we all groan because we desire to be clothed in our house made in heaven:
2 Corinthians 5:
4 For we that are in this tabernacle do groan, being burdened: not for that we would be unclothed, but clothed upon, that mortality might be swallowed up of life.
5 Now he that hath wrought us for the selfsame thing is God, who also hath given unto us the earnest of the Spirit.
6 Therefore we are always confident, knowing that, whilst we are at home in the body, we are absent from the Lord:
The fellowship with the Father we enjoy in this lifetime is through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known (1 Cor 13:12).
I see your point and have thought about this a lot because it does seem to be talking about the literal earth and heaven, maybe you can help me figure it out.
When I read these verse I see the time when God chose the Gentiles, and this happened at the cross. I also see the rest of those verses speaking of the destruction of Israel in AD 70. Then verse 17 talks about the new heaven and the new earth coming immediately after the AD 70 destruction. How do you see these verses?

Isa 65:17
For, behold, I create new heavens and a new earth: and the former shall not be remembered, nor come into mind.
