The God of the Bible is the God of the whole earth. Yet, His promise of this one little piece of land to one family - the descendants of Abraham through Isaac and then Jacob - is confirmed and repeated in the scriptures 46 times. Clearly, this attention affirms the importance of the land in God's purposes. Land is a necessary element for forming a nation, and here it provided an essential foundation for the children of Israel to grow in numbers and build a national identity with national institutions.
The land also provided a stage on which the Almighty God carried out his plan of world redemption. Since the gifts and callings of God are irrevocable (Romans 11:29), and Israel would never cease to be a nation before Him (Jeremiah 31:36), their possession of this land is also everlasting (Genesis 17:8). Indeed, God's faithfulness to this Covenant is held up before discouraged believers in the Book of Hebrews as proof that He will be faithful to the promises made to them in the New Covenant (Hebrews 6:13-20).
