Of the Major Prophets, Isaiah has arguably had the greatest influence on Jewish and Christian theology. Like many of the prophets, Isaiah delivered a message that few people wanted to hear: God’s people had allowed their hearts to grow corrupt, centered around empty religious practice. Isaiah called God’s people to return to true worship or face judgment. While calls for repentance and warnings of punishment characterize the first half of Isaiah, the second half emphasizes a messages of hope and forgiveness.
Isaiah is a dense book, full of fascinating detail. Because Isaiah interacted directly with several of Judah’s kings, this book describes some of the significant moments in the reigns of Ahaz (Isaiah 7) and Hezekiah (Isaiah 37), among other rulers. But Isaiah is most famous for his descriptions of God’s Messiah, among which is the passage from Isaiah 53.
