Dr. John N. Oswalt's opening volume on Isaiah 1-39 launches what has become the definitive evangelical commentary on this most important prophetic book, establishing the scholarly and theological foundation for understanding Isaiah's comprehensive vision of divine holiness, human sinfulness, and ultimate redemption. As Distinguished Professor of Old Testament at Asbury Theological Seminary and a recognized world authority on Isaiah, Oswalt combines exceptional expertise in Hebrew language and ancient Near Eastern studies with profound commitment to evangelical scholarship, producing a commentary that serves both serious academic research and practical ministry needs. His extensive introduction addresses crucial questions of background, unity, authorship, and theology that provide essential framework for understanding Isaiah's prophetic message.

Oswalt's methodological excellence demonstrates his mastery of both detailed exegetical analysis and broader theological synthesis, providing readers with fresh insights into how Isaiah's opening chapters establish the themes and patterns that govern the entire prophetic book. His treatment of key passages like Isaiah's temple vision in chapter 6, the Immanuel prophecies of chapters 7-9, and the messianic vision of chapter 11 reveals the sophisticated literary artistry and theological depth underlying these familiar texts. His defense of Isaiah's unity and single authorship provides compelling evidence for understanding the entire book as the coherent vision of the eighth-century prophet, while his detailed verse-by-verse commentary illuminates both historical context and contemporary relevance.

This substantial volume serves as an indispensable foundation for pastors preparing to preach from Isaiah's challenging prophecies of judgment and hope, seminary students beginning serious study of Old Testament prophetic literature, and thoughtful Bible readers seeking to understand how ancient prophetic messages continue to speak to contemporary faith challenges. Reviewers have praised this work as "one of the flagship volumes" in the NICOT series and "a treasure" that provides "solid help in understanding the text and message of this Old Testament book." Oswalt's scholarly excellence, combined with his ability to make complex theological concepts accessible, ensures that this commentary will serve as the standard evangelical treatment of Isaiah 1-39 for generations to come, making it essential for anyone seeking comprehensive engagement with one of Scripture's most theologically significant and spiritually transformative books.
