The book of Jonah is arguably just as jarring for us as it was for the ancients. Ninevah's repentance, Jonah's estrangement from God and the book's bracing moral conclusion all pose unsettling questions for today's readers. For biblical theologians, Jonah also raises tough questions regarding mission and religious conversion. Here, Daniel Timmer embarks on a new reading of Jonah in order to secure its ongoing relevance for biblical theology. After an examination of the book's historical backgrounds (in both Israel and Assyria), Timmer discusses the biblical text in detail, paying special attention to redemptive history and its Christocentric orientation. Timmer then explores the relationship between Israel and the nations--including the question of mission--and the nature of religious conversion and spirituality in the Old Testament. This New Studies in Biblical Theology volume concludes with an injunction for scholars and lay readers to approach Jonah as a book written to facilitate spiritual change in the reader. Addressing key issues in biblical theology, the works comprising New Studies in Biblical Theology are creative attempts to help Christians better understand their Bibles. The NSBT series is edited by D. A. Carson, aiming to simultaneously instruct and to edify, to interact with current scholarship and to point the way ahead.
