The growth of Spirit-empowered Christianity has been nothing short of phenomenal. From a handful of believers in the early twentieth century to over six hundred million people in almost every culture and denomination today, those who embrace the Holy Spirit and His gifts are now the fastest-growing religious group in the world. But if any generation ceases to emphasize the Holy Spirit's power, the movement likely will lose this distinction. This final volume is an authoritative collection from more than two dozen leaders and scholars of the Spirit-empowered movement. In addition to addressing the history and future of the movement, this book discusses global theological topics, including the emergence of prosperity theology, and focuses on the possibilities and challenges for Pentecostalism.
