Abram was promised that he would become a great nation, a nation that would in future generations be given a land in which to dwell. It was years before Abram and Sarai would have the son, Isaac, who was the promised heir, and it would be hundreds of years before the children of Israel would possess the land. When we read the story of Abram and Sarai in Genesis, we read of moments when Abram's faith in God wavered, when he seemed not at all sure that God would keep the promise. But in the end, Abram "believed God, and it was reckoned to him as righteousness." (Romans 4:3)
This past weekend our son Matthew graduated from law school. He has a diploma and a job that will begin in September, but much of his time during the next two months will be spent preparing for the bar exams, and he expects that he would not be admitted to the bar before next February. Like so many graduates, Matthew will journey by stages towards his goal. Like so many graduates, he will have moments when we wishes that the goal could be achieved in an instant. And like his father before him, he may struggle with impatience. In the end, however, I believe that he will trust that God has called him and has been preparing him for this vocation , and he will travel by stages towards the realization of God's promise.
