Book 23 of 39 in the Old Testament — Judgment & the coming Messiah.
Isaiah is the longest of the prophetic books, spanning warnings of judgment against Judah and the surrounding nations alongside some of the Old Testament's clearest promises of future hope. The prophet confronts idolatry and injustice, foresees Jerusalem's coming fall to Babylon, yet also promises a future remnant, a restored Jerusalem, and a coming servant-king who would suffer for his people's sin. Passages like the suffering servant of chapter 53 are read by Christians as pointing directly to Jesus. Its scope — judgment and hope intertwined — makes it central to Old Testament prophecy.
