Isaiah is widely considered the deepest, richest, and most theologically significant book in the Old Testament. It is, without question, a profound statement by God about his own sovereignty and majesty spoken through his chosen spokesman, the prophet Isaiah. In this accessible commentary on the book of Isaiah, Raymond C. Ortlund Jr. argues that Isaiah imparts a single vision of God throughout all sixty-six chapters. It is a unified, woven whole that ultimately shows that God saves sinners. He saves them from their own self-invented salvations, so that they can walk in the light of his love. Ultimately, the message of Isaiah offers us a God-centered confidence that enables us to face anything while challenging us to trust God in new ways. Part of the Preaching the Word series.
