How did Christianity spread from a small room of frightened Jewish believers in Jerusalem to a movement that would challenge and eventually overcome Rome, the center of first-century civilization? Capable scholars have written much about this phenomenon, and we are still experiencing its effects today. But to understand first-century Christianity we must begin in Acts—the inspired book itself, and not in outside scholarship. We must read it for ourselves. This devotional is an eighty-day study in Acts that guides you through the history, language, and culture of the first century and inculcates strong Bible study habits along the way. At the end you will have truly discovered Acts.
