The life of Abraham is an illustration of two things:

of unreserved surrender to God, and of God’s complete possession of a child of His for His own highest end.

God’s purpose for our life is to bring Him glory.  The chief end of man is to glorify God by enjoying Him forever. This is not man’s goal, but God’s goal for man. This is best accomplished when we unreservedly surrender to God.  This surrender doesn’t happen until we realize the unconditional love Jesus demonstrated on the cross and continues to pour into to our lives. Do you realize that God’s possession of you is unconditional and eternal?
