This is not just a book about Abraham, Isaac, Jacob and Joseph although they are the main subjects. More than that, Dr. Harrison is presenting a book about faith, a book about personalities, and a book that raises many questions about the purpose and intent of the characters involved. To be sure, God is very much included in all the scenarios.
Abraham and Joseph are the bookends and establish the framework for God's purpose- the nation of Israel. The narrative never takes us out of Egypt; Joseph and Jacob's kin find a resting place there where they can flourish and grow into a healthy social culture some 500 years later. All part of God's plan to give the Patriarch's descendants the tools, politic and wisdom to be a distinct and lasting nation, schooled in many ways by a rich Egyptian culture.
