Major Prophets
Author(s):
Isaiah
Old Testament
📖 What It’s About
Isaiah is a sweeping prophetic masterpiece that calls a rebellious people to repentance while revealing breathtaking visions of God’s holiness, justice, and redemption. Written during the rise and fall of kings and empires, it speaks to both the immediate situation of Israel and Judah and the distant promise of a coming Savior.
The first half of the book (chapters 1–39) focuses on judgment for sin, idolatry, and injustice. The second half (chapters 40–66) unfolds God’s plan of comfort, restoration, and salvation — highlighting the suffering servant and the glorious future of God’s Kingdom.
Isaiah is often called the “fifth Gospel” because of how clearly it foreshadows Jesus — His birth, ministry, suffering, death, and reign.
