Isaiah
66 chapters · Old Testament
Isaiah son of Amoz ministered in Jerusalem during the reigns of four Judean kings, roughly 740–700 BC, making his one of the longest prophetic careers in Scripture. The book bearing his name is sometimes called the 'Fifth Gospel' because of its remarkably detailed anticipations of Jesus Christ. Scholars have long discussed whether the book's two major sections reflect one author writing across decades or multiple contributors, but Christian tradition and many scholars affirm a unified Isaianic authorship, trusting that the Holy Spirit enabled genuine predictive prophecy.
Isaiah's central burden is the holiness of God — he encountered the Lord 'high and lifted up' in his opening vision, and that encounter shaped everything he wrote. The book confronts Judah's idolatry, injustice, and misplaced trust in foreign alliances, calling the people back to covenant faithfulness. Yet judgment is never the final word. Isaiah soars into magnificent promises of restoration: a Suffering Servant who bears the sins of many, a new creation, and a kingdom of lasting peace. These themes have nourished the faith of Jewish and Christian readers for centuries and find their deepest fulfillment in the life, death, and resurrection of Jesus.
