God offers to each of us at least two great moments in life: the moment when we were born—though we might not wish to dwell on the number of birthdays from that day to this—and the moment we realize why we were born. All experience the first. Many never experience the second; many never find and fulfil the central purpose of their lives.
However, there is help. It comes to us in the form of an ancient biography, in the life of a man who discovered his purpose after years of determined and demanding study of Scripture.
