The book of Job may raise more questions that it gives answers about God, suffering, Satan and faith. However, one of the things we know is that part of the answer as to why Job lost everything is because God was pleased with him. "No way" you say "God blesses those that he is pleased with." Want proof...here it is "Have you considered my servant Job? There is no one on earth like him" 1:8. God points Job out to Satan because he is pleased with Him. Job stands not only as an exception, but as a demonstration that God may allow suffering for reasons beyond our knowledge.
