Thoughts sparked in Genesis

What is the hope of the Christian? Is it not that someday, we will have a "rest", a place of eternal life with God? As I have been reading in Genesis, the concept of rest keeps coming up, not because Genesis talks about it, but exactly the opposite.

  Look through your Bible, especially the Pentateuch, and you do not find rest in this life; you find people who were sojourners and pilgrims and wanderers on this earth, people who were looking for a future rest in a Promised Land. Then, turn to the NT and remember that this world is not our home, we really are just passing through; indeed we are strangers and pilgrims. Now then, brothers, let us live as ambassadors, those who are sent to a foreign country, and it is in service to the King, not for ourselves!
