Dig into Dear Theophilus, Isaiah: 40 Prophetic Insights about Jesus, Justice, and Gentiles.

In this 40-day Bible study, step into the world of Isaiah, a prophet with a powerful message that still resonates today. In this beloved prophetic book, Isaiah delivers prophecies that not only speak to the near future of his people but also look forward to the coming of Jesus and the salvation he brings.

But Isaiah doesn't just predict events. He challenges us in how we worship God and live our lives.

Join Bible teacher Peter DeHaan on a journey of discovery into Isaiah’s prophecy. Let his words challenge and inspire us to live a life of true worship and to influence those around us.

Although Isaiahs key message was directed toward the Israelites, his words bring hope and comfort to a weary world today. Dear Theophilus, Isaiah reminds us that Jesus not only came to dwell among us, but is still our wonderful counselor, mighty God, everlasting father, and prince of peace.

Dear Theophilus, Isaiah offers practical teaching and inspirational encouragement as we study the Old Testament prophecies of Isaiah and their connection to Jesus and how we live today.

God tells his people back then—and us today—that their sacrifices and celebrations are meaningless because their hearts are not right with him. Instead, God desires practical action, like seeking justice, defending the oppressed, and helping those in need.

This Bible study is perfect for personal reflection or group study. Bonus sections enhance our understanding of key themes and passages in Isaiah.

As we delve into the teachings of Isaiah, we are forced to confront our own worship practices. Are we truly honoring God, or are we simply going through the motions? Are our actions making a difference in the world around us, or are they falling short of God's expectations?

Peter DeHaan writes about biblical Christianity to confront status quo religion and live a life that matters. He seeks a fresh approach to following Jesus through the lens of Scripture, without the baggage of made-up traditions and meaningless practices.
