The book of Job is a test in how well the reader can resist scapegoating a blameless victim. The key to the whole book is found in the first verse. Job was blameless. But most readers fail the test and end up at some point agreeing with Job's three "miserable comforters" and the most vicious accuser of all, Elihu. But Job was BLAMELESS! Can the reader remember this all the way through? Most readers cannot; eventually they side with the accusers—the satan. We are possessed!
