The book of Job is famous for its complex and compelling exploration of suffering and faith. It is less well-known for its contribution to a biblical understanding of God's mission and the church's role within it. In this detailed study, Tim J. Davy provides the most in-depth treatment yet of a "missional" reading of Job, building on the great strides taken in recent years in the missional reading of Scripture. A number of missiologically framed questions are examined, including the function of the book's non-Israelite theme, the cultural encounter of Job with similar ancient Near Eastern literature, and questions of justice and the treatment of the poor. Ultimately Davy makes the bold claim that the book of Job lies, not at the periphery, but at the heart of our understanding of the mission of God.
