Summary
Isaiah 40–66 by John N. Oswalt offers a weighty and pastorally aware interpretation of the second half of Isaiah. The volume begins with a careful survey of critical debates: Questions of authorship, date, structure, and the unity of the book, and then proceeds to a verse-by-verse commentary grounded in a fresh translation. Oswalt balances respect for the Hebrew text and its ancient context with the conviction that this prophetic word still speaks to modern believers. He does not shy away from the grand promises of restoration, the warnings of judgment, nor the messianic and eschatological overtones that echo into the New Testament.
Throughout the commentary, the prophetic narrative is treated as both historically rooted and theologically profound. Oswalt draws attention to the themes of exile and return, the suffering and vindication of the Servant, and the sovereignty and comfort of God, placing Isaiah’s message in its canonical context. He helps readers appreciate the tension and hope contained in the text, and leaves space for preaching that honours the prophetic voice while bridging to gospel realities.
This volume is not a devotional handbook nor a sermon workbook; rather it provides the exegetical and theological foundation any preacher needs before building application. Used carefully, it ensures that prophecy is preached with reverence, clarity, and a sense of gospel-anchored hope.
Why Should I Own This Commentary?
If you are regularly preaching or teaching in Isaiah, this commentary is indispensable. When you face complex prophecy, with difficult Hebrew, rich imagery, and shifting horizons between immediate judgement and ultimate redemption, Oswalt gives you a sure footing. His translation and notes clarify grammar, poetic structure, and variant readings so you are not forced to guess. That reliability is a pastor’s friend.
For Reformed preachers who want to handle the Old Testament with theological integrity and gospel sensitivity, this volume does strong service. Oswalt defends the unity of Isaiah and treats 40–66 as part of one prophetic message. That guards against fragmented or arbitrary interpretation and encourages preaching that honours the consistency of God’s redemptive revelation across covenant, exile, and promise.
Though dense, the book is organised and navigable. For pastors with limited preparation time, the combination of translation, structured commentary, and accessible prose makes it feasible to consult during sermon planning. It will repay repeated use over many years, a worthy foundation for faithful, text-driven preaching on Isaiah.

It combines textual fidelity, theological depth, and canonical awareness in a way that honours Scripture and serves the church. For any pastor determined to preach Isaiah with clarity, conviction and gospel-grounded hope, this volume belongs on the shelf.
