The Kingdom of God will eventually fill the whole earth with the New heavens and the New earth. The Types and shadows of the Old Testament point to the substance of their fulfilment in the Lord Jesus Christ

In Genesis 1-11 there were three themes of sin, judgment and grace. But in Genesis 11 there is no sign of God's grace. We have to wait until Genesis 12. God appears to Abram and promises to reverse the effects of His judgment after the Tower of Babel. God declares His intention to bring back the scattered people of the world and to bless them once more.
God's words to Abraham are the first clear statement of His promises of the Gospel. These promises in Genesis 12v1-3. Although God gave us a glimpse of the Gospel in Genesis 3v15 with the promise that the Seed of the woman would crush the head of the serpent.
But these promises in Genesis 12v1-3 will dominate the rest of the Bible as they unfold in the progressive unfolding revelation of the Gospel of the Kingdom of God.

In other words, Genesis 12v1-3 is the text that the rest of the Bible expounds. There were 3 main elements to the promises that Abraham received: People; Land and Blessing

Galatians 3, Romans 9v6-8 and John 8 are pointed out in this discussion as just a few examples of who the REAL seed of Abraham really are- those who are united to Jesus Christ in union with Him so that there is neither Jew, nor Greek, male nor female, slave nor free, for you all one in Christ Jesus and if you are Christ's, then you are Abraham's seed, and heirs according to the promise' (Galatians 3v28-29)

Therefore the Christian Zionist belief that physical ethnic Jews even if they are not in union with Christ by the Holy Spirit are still in an eternal covenant with God and are still God's special chosen people is false and deceiving countless millions.
