INTRODUCTION. God promised Abram He would make of him a great nation and give to that nation (Abram's seed) the land of Canaan. These promises are called the nation-land promise. In addition God told Abram that in him all families of the earth should be blessed. This promise is called the spiritual promise. Since it is impossible for God to lie (Heb. 6: 18), these promises were unconditional or absolute; that is, the descendants of Abram would receive from God all that God had promised.
Although Abram believed God and obeyed, leaving his home in Ur and traveling to an unknown country, he was old and had no children. How could these promises come to pass? After some time the word of the Lord appeared to Abram in a vision, assuring him he would have an heir. God also told Abram his seed would dwell in a land not theirs for four hundred years, but in the fourth generation they would come out of that land and enter into the land of Canaan. God then told Abram the boundaries of his land inheritance.
