Les teaches that whenever he teaches about Abraham, he always points out that all the things concerning Abraham and his earthly people, the nation of Israel, are always earthly. God promised Abraham a nation of people that would bring about the Redeemer, the King, the nation, and their geographical area, and through it all God's purposes would be fulfilled. This earthly focus is confirmed by the promise that the race of Israel shall not pass until all things be fulfilled, despite opposition and intermarriage.
