Correct 1000 yrs is not eternity but that is what was believed. That's the point.
Now I want to show you something very simple to understand and we all know this out line of the prayer that Jesus gave to us.
Thy kingdom come....thy will be done on earth....as it is in Heaven.
you and others here keep pointing to spiritual concepts so may I ask you what is heavenly fulfillment?
where in scripture does it say Jesus restores anything in heaven, who did jesus redeem in heaven the angles?
all of the restoration, all of the redeemed, the sacrifice, all of it is on earth...earthly.
God is not imposing his authority he's establishing it. ....In the beginning God created the heavens and earth.
The earth was always Gods. God was always God the almighty.
The scrolls are the deed to the earth. You said they are already opened? When and where for only the sacrificed lamb of God can open.
My understanding of spiritual restoration is on both heaven and earth (Rev.21).
There are also restorations in heaven described in the Bible, Rev. 12:7-12 for example, and they all greatly effect the affairs of earth.
The resurrection as it is described in 1 Cor 15 involves a bodily resurrection, but the body becomes a heavenly body, ie immortal and incorruptible.
The world of the resurrection is also the kingdom of heaven.
Romans 4:13 For the promise, that he should be the
HEIR OF THE WORLD, was not to Abraham, or to his seed, through the law, but through the righteousness of faith.
If we just read Genesis we would not understand that it was promised to Abraham that he would be heir of the whole world.
That is yet another reason we should allow the NT to interpret the OT.
The eternal land promise in Genesis 17:8 is not just a repeat of the same promise made in Genesis 15:18-21 that the seed of Abraham would possess the land of Canaan (which they did through the law).
Abraham is promised that he will have an everlasting possession through the righteousness of faith, and it includes the land of Canaan, but it also includes the whole new earth.
The heirs of this promise to Abraham are not necessarily Israelis, but all who are made righteous through their faith in Jesus.
This promise is not to those that reject Jesus, so in the resurrection there indeed will be no more "Canaanite" in the land.
