Isaiah, it has been said, is the Old Testament evangelist par-excellence. While every book in the Old Testament points to Christ as the fulfilment in the New Testament, few do so as overtly or as insistently at the book of Isaiah. The text became a framework for Christology, ecclesiology, and missiology in the early church, and along with the Psalms it remains most quoted scripture in the New Testament. In this volume on chapters 40-55, Dr. Lessing's scholarly expertise and decades of service as a seminary professor and pastor are evident as he meticulously expounds the text, historical setting, theology, Christology, and pastoral applications of the 40-55th chapters of "the fifth Gospel." Using a faithful, Christo-centric hermeneutic, he focuses on the Isaiah's visions of "shalom" and Israel's peaceful homecoming from the Babylonian exile and explains why the prophet's saving message, soaring language, and unforgettable imagery are so tightly woven into the fabric of Christian hymnody, liturgy, and prayer. He also features the four "servant songs," espousing the traditional interpretation that they sing of Christ and addressing alternatives that have emerged in recent academia. EssaysThe Literary, Historical, and Canonical Context of Isaiah A History of Studies on Isaiah The Servant Songs in Isaiah About the series The Concordia Commentary Series: A Theological Exposition of Sacred Scripture is written to enable pastors and teachers of the Word to proclaim the Gospel with greater insight, clarity, and faithfulness to the divine intent of the Biblical text. The series will cover all the canonical books of the Old and New Testament, with an original translation and meticulous grammatical analysis of the Hebrew, Aramaic, or Greek of each text. The foremost interpretive lens centers on the unified proclamation of the person and work of Christ across every Scriptural book. The Commentary fully affirms the divine inspiration, inerrancy, and authority of Scripture; Each passage bears witness to the confession that God has reconciled the world to Himself through the incarnation, ministry, death, resurrection, and ascension of Christ His Son. Authors expose the rich treasury of language, imagery, and thematic content of the Scripture, while supplementing their work with additional research in archaeology, history, and extrabiblical literature. Throughout, God's Word emanates from authors careful attention and inculcates the ongoing life of the Church in Word, Sacrament, and daily confession.
