This book explores the identity, context, and features of Pentecostalism in Rajasthan, India, as well as the internal and external issues facing Pentecostals. It argues for an indigenous origin of Pentecostalism in Rajasthan, as it is a product of local Spirit revivals in the existing churches and of the missionary activities of Indian Pentecostals. The book aims to suggest a contextual missiology of the Spirit as a new model of contextual missiology from a Pentecostal perspective. It is presented as a glocal, ecumenical, transformational, and public missiology.
