Overview

Isaiah is often called the 'Gospel of the Old Testament' because of its extraordinary concentration of Messianic prophecy. The book divides naturally into two major sections: chapters 1-39, focusing on God's judgment against Israel, Judah, and surrounding nations; and chapters 40-66, which pivot to breathtaking promises of comfort, restoration, and redemption.

Isaiah ministered in Jerusalem during the reigns of four kings from approximately 740 to 700 BC. His call in chapter 6 — a vision of the Lord seated on a heavenly throne surrounded by seraphim — is one of the most dramatic in all of Scripture. Isaiah's response: 'Here am I. Send me!' became a model of willing service.

Chapter 53 is perhaps the most remarkable chapter in the Old Testament — a detailed portrait of the Suffering Servant who bears the sins of many, written 700 years before the crucifixion. Philip uses this very chapter to introduce Jesus to the Ethiopian eunuch in Acts 8. Isaiah's 66 chapters mirror the 66 books of the Bible in many structural ways.

Study Notes

Isaiah is quoted in the New Testament more than any prophet except Psalms. Matthew, Mark, Luke, John, Acts, Romans, and Revelation all draw extensively from Isaiah. The book has been found among the Dead Sea Scrolls (the Great Isaiah Scroll, ~125 BC), confirming the accuracy of its textual transmission. Isaiah's servant songs are crucial to New Testament Christology.
