Dr. John N. Oswalt's concluding volume on Isaiah 40-66 completes what is universally recognized as the finest evangelical commentary on Isaiah available today, providing the definitive treatment of the prophet's magnificent vision of redemption, restoration, and hope. As the second installment of his acclaimed two-volume NICOT series, this 773-page masterwork demonstrates why Oswalt is considered one of the world's leading authorities on Isaiah, combining unparalleled expertise in Hebrew language and ancient Near Eastern studies with profound theological insight and pastoral sensitivity. His comprehensive approach to these climactic chapters of Isaiah addresses the complex scholarly debates surrounding the book's unity while maintaining a clear focus on the theological message that has inspired believers for millennia.

Oswalt's groundbreaking contribution lies in his compelling defense of Isaiah's unity and single authorship, demonstrating how chapters 40-66 function as an integral part of the eighth-century prophet's total vision rather than the work of later anonymous writers. His detailed exegetical analysis reveals the sophisticated literary and theological connections that bind these chapters to the earlier portions of the book, while his treatment of the Servant Songs, the restoration oracles, and the vision of new creation provides essential insights into some of Scripture's most beloved and theologically significant passages. His work on texts like Isaiah 53's suffering servant and Isaiah 55's invitation to "come, buy and eat" illuminates both their historical context and their profound fulfillment in Christ, making this commentary indispensable for understanding the prophetic foundations of Christian faith.

This substantial scholarly achievement serves as an essential resource for pastors seeking to preach faithfully from Isaiah's messages of hope and restoration, seminary students pursuing advanced Old Testament studies, and serious Bible readers wanting to understand how Isaiah's vision of divine redemption continues to shape Christian theology and practice. Reviewers have praised this work as "clearly the best commentary available on Isaiah" and "the standard American evangelical exposition of Isaiah 40-66," noting Oswalt's exemplary scholarship and his ability to make complex theological concepts accessible to contemporary readers. His commentary demonstrates why Isaiah 40-66 remains central to Christian understanding of God's redemptive purposes, making this volume indispensable for anyone seeking comprehensive engagement with one of Scripture's most theologically rich and spiritually inspiring books.
