It is said that when Augustine, shortly after his conversion, asked Ambrose of Milan which book he should begin with in his study of the Bible, the answer he received was, “The prophecies of Isaiah.” Isaiah has been called “the gospel before the Gospel.” Homer Hailey, in the preface of his widely read commentary on Isaiah, referred to Isaiah as “the dean of all Old Testament prophets.” Isaiah’s timeless message of faith in the “Holy One of Israel” is as relevant today as it was when he first delivered it. In a dark world given over to the futility of idolatry and false religion, Isaiah extols the glory and majesty of Jehovah. In an age of sin and unfaithfulness, the prophet declares God’s absolute holiness and His infinite love. In a time of hopelessness and despair come a message of hope and a promise of human redemption through a Messiah—God’s Servant. This series of lectures calls us to a study of the prophesy of Isaiah. They present several “Portraits in Isaiah” to help us better appreciate this great man and his great message.
