At this critical point in the history of World Missions, it is imperative for us to take a step back from “business as usual” in our work around the globe and reevaluate the strategies and methods we are implementing. What is working? What isn’t? If we’re honest, there may be more not working than we would care to admit. In this book, written in the early 1900s, Roland Allen invites us to look at the missionary work of the Apostle Paul with fresh eyes and an igniting perspective that is strikingly relevant to the greatest challenges we are facing today in modern missions. He offers a well of insight from the methodology of Paul that will focus and unite us as we draw nearer than ever before to our goal of fulfilling the Great Commission and reaching the world with the Gospel of Jesus Christ.
