Isaiah 60–66 brings the book to a sweeping conclusion of glory, judgment, and renewal. Zion is called to arise and shine as God’s light draws nations, while the LORD promises justice, restoration, and comfort to the faithful.

At the same time, God confronts hypocrisy and rebellion, making clear that true worship is marked by humility and obedience. The book ends with a vision of new heavens and a new earth, where God dwells with his people, righteousness endures, and all flesh acknowledges the LORD.
