How and why is Christianity's center of gravity shifting to the developing world? To understand this rapidly growing phenomenon, Donald E. Miller and Tetsunao Yamamori spent four years traveling the globe conducting extensive on-the-ground research in twenty different countries in Africa, Asia, Latin America, and Europe. The result is this vividly detailed book and accompanying DVD, which together contain the most comprehensive information available on Pentecostalism, the fastest-growing religion in the world. Rich with scenes from everyday life, the book and DVD dispel many stereotypes about this religion as they build a wide-ranging, nuanced portrait of a major new social movement. The DVD features footage of Pentecostal religious worship, testimony, and social activism, and includes interviews with Pentecostal pastors and leaders from around the world.
