The Book of Job is one of the few places where you see Satan arguing with God in the Bible. For the Adventists with the Great Controversy view of redemption, it's important. It's interesting how God says Job is perfect and the rest of the book is arguing about whether that is right or not. At the end, God comes and says "Job has said of me what is right."
