Why Love God? (Job 1)

The story of Job opens with a man who is righteous, fears God, and turns from evil.  This is a man who lives out the wisdom of the gospel as he even sacrifices a burn offering in case one of his children cursed God in their heart.  This is a man who is worthy of blessing and a man who deserve blessing from the hand of God.  So, what sort of wisdom is being communicated to us when Job receives the exact opposite of what he deserves?  What is the driving force of Job’s suffering?  Does Job really love God because of who God is or does Job love God because of what God can do for Job?
