Alan Hirsch is convinced that the inherited formulas for growing the Body of Christ do not work anymore. And rather than relying on slightly revised solutions from the past, he sees a vision of the future growth of the church coming about by harnessing the power of the early church, which grew from as few as 25,000 adherents in AD 100 to up to 20 million in AD 310. Such incredible growth is also being experienced today in the church in China and other parts of the world. How do they do it'The Forgotten Ways explores the concept of Apostolic Genius as a way to understand what caused the church to expand at various times in history, interpreting it for use in our own time and place. From the theological underpinnings to the practical application, Hirsch takes the reader through this dynamic mixture of passion, prayer, and incarnational practice to rediscover the dormant potential of the modern church in the West.
