Isaiah 40-55 contains some of the best-known, most-cherished, and theologically significant texts in the Bible. Isaiah 40-55 provides us with the vocabulary and conceptual framework to understand the nature and purpose of the Father's mission in and through his Son, Jesus, with the Spirit (from the introduction). 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 fifth Gospel." He 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. Pericopes from chapters 40-55, which include the Suffering Servant Songs, permeate the lectionary throughout the church year. - Publisher.
