The book of Isaiah is the most quoted portion of the Old Testament in the New Testament. Clearly, it’s an important portion of Scripture. But if you’ve ever read through Isaiah, you might relate with the feeling of being lost. In this high-level series through Isaiah, we take a tour of this magnificent book. In the course of the series we come to see the unity and beauty of Isaiah’s prophecy. Isaiah opens with a vision of God’s people in rebellion and sin, and closes with a vision of a shining, singing, and secure city. How does the Jerusalem of chapter 1 become the Jerusalem of the end of the book given the unapproachable holiness of God, and how can we find ourselves in it? That’s the question we seek to answer together.
