"Job never receives an explanation for his suffering. Job loses his family, his material prosperity and his health, yet God never tells him that he was being tested by Satan, nor is the reader told why God wants Job to endure such testing. For much of the book, Job is left without any tangible response from God. When God does speak, He essentially tells Job that he does not understand, but that He, God is good and sovereign. God answers not by changing Job’s situation right away, but by showing Job that he has not been abandoned.
In the end, Job receives a double portion of blessing; his health is restored and he has more children. Yet, even though this story has a "good ending" of sorts because Job is blessed for keeping his integrity by refusing to curse God, it leaves the reader unsettled. Job does not receive his children back. Job is never given an answer from God except, "I know what I’m doing, trust Me."
The book of Job emphasizes that man cannot understand God’s purposes and calls man to trust that God knows what He is doing and will bless those who take refuge in Him. In essence, there is no purpose to questioning God. God is good and God is in control."
This makes me think of Orual's situation. "Are you answered?" asked the gods of Orual. "Yes. You yourself are the answer."
