The book of Job is a vivid testimony to pain, a plea for justice, and a wrenching theological debate about suffering and its causes. Central to this debate are questions about the roles that God and humans play in causing human suffering and whether divine-human relationships can proceed in the midst of overwhelming anguish. Like a riddle, the text grasps readers' minds and emotions, inviting them to participate in Job's story and to work toward their own solution to the dilemmas of both Job and his friends. Kathleen M.
