Hamilton Smith conducts a verse-by-verse study of chapters 40 to 57 of the Old Testament prophecy of Isaiah. Emphasis is placed on the dispensational approach to its interpretation, distinguishing prophecies as already fulfilled, or yet to be so. The focus of chapters 40 to 48 is seen as the issue of idolatry; and that of chapters 49 to 57 to be the coming of Jesus as the humble servant of God, to be followed by his future return to rule. Throughout the exposition valuable practical lessons are drawn for Christians today.
