Isaac's life is defined by his marriage to Rebekah, his twins sons, and the Abimelech. We know much about the character of Isaac not explicitly but through the character of the people around him.

This message develops the theme of despising one's birthright as the oldest son of Isaac did. It teaches us the danger of becoming indifferent to our own birthright. It also teaches us the danger of indulging in earthly things.

Theologically, this sermon develops the speaker's view of election: national and personal.
