The Book of Isaiah, authored by the prophet Isaiah, is one of the most influential and far-reaching books in all of Scripture. Isaiah’s ministry began around 740 BC during the reign of King Uzziah and continued through the reigns of several Judean kings—including Jotham, Ahaz, and Hezekiah—spanning a turbulent period in Israel’s history when both the northern and southern kingdoms faced threats from powerful empires like Assyria.

Traditionally, Isaiah is recognized as the primary author of the book that bears his name. He was called by God to deliver a bold message of judgment against sin, but also of hope and restoration for all who would turn to the Lord. His prophecies speak to the immediate circumstances of his day—warning of coming exile and calling God’s people to repentance—but they also look far beyond, pointing to a future Messiah and the promise of salvation for the whole world.

Isaiah is renowned for its vivid imagery, poetic brilliance, and unforgettable visions of God’s holiness and glory. Its pages include some of the clearest prophecies about Jesus Christ—such as the virgin birth (Isaiah 7:14), the suffering servant (Isaiah 53), and the reign of the coming King.
