God promised Abraham that as he had kept faith in god and obeyed god , he would be a father of a great nation.
He obeyed God and would sacrafice his son for God.
God didn't promise Abraham anything. God just told him to sacrifice his son Isaac and Abraham, being obedient to God, was going to do what God told him to do. That is until God stopped him. God was seeing if Abraham would still be willing to obey God even if it meant killing his only son.
A:Leon R. Kass (The Beginning of Wisdom: Reading Genesis) says that in a strange way the passage about Abraham's willingness to sacrifice his son speaks more about God's faith in Abraham than Abraham's faith in God. Kass also cites an insightful comment from a student he taught at his university. If you say that Abraham, when he goes up Mount Moriah, neither hopes nor believes in the slightest that Isaac will somehow be saved or restored at the end of it all - if you say that Abraham has resigned himself wholly to the loss of his son Isaac - then you must also say . . . that Abraham is here offering Isaac to a God whom Abraham believes to be a liar. For did not God promise that "it is through Isaac that offspring shall be called for you (Genesis 21:12)?

Isaac is sometimes called "the child of the promise" because God promised Abraham that Sarah would have a son despite her old age, and Isaac was born miraculously fulfilling that promise. Isaac's birth symbolizes God's faithfulness in keeping His promises to His chosen people.
