"Notice again God’s promise to him: “I will make you a great nation; I will bless you and make your name great; and you shall be a blessing. I will bless those who bless you, and I will curse him who curses you; and in you all the families of the earth shall be blessed” (Genesis 12:3).
What a fantastic commitment! With these promises God set in motion an awesome design destined to benefit “all the families of the earth” when they are fulfilled. The history and prophecies of this nation, springing from Abraham, are important not only for its own people but for the people of all nations."
"Almost 800 years after Israel disappeared as a nation, the apostle Paul described gentiles (non-Israelites) who are “without Christ” as “aliens from the commonwealth of Israel and strangers from the covenants of promise, having no hope and without God in the world” (Ephesians 2:12).
This means that God must graft all who become His servants into the family of Abraham, and God has bound Himself by a series of covenants to accomplish this (Romans 11:13-27).
God continued: “Also I give to you and your descendants after you the land in which you are a stranger, all the land of Canaan, as an everlasting possession; and I will be their God … You shall keep My covenant, you and your descendants after you throughout their generations” (Genesis 17:8-9). The account in Genesis 17 establishes God’s commitment to Abraham as an “everlasting covenant” (Genesis 17:7-19), a binding agreement obligating God to give the patriarch’s descendants the land of Canaan in perpetuity (Genesis 17:8). God’s commitment to Abraham was major and far-reaching.
