This groundbreaking work showcases a new approach for reaching new religious movements, cults, and sects. Countless new religious movements (NRMs) have sprung up across the United States and around the world in the last century. The many scholars and pastors contributing to this book have found that the best way to approach these groups is not to point out Biblical heresies and doctrinal aberrations, but instead to view NRMs as mission fields, much like we view foreign people groups. The authors of this volume demonstrate that the gospel needs to be contextualized for NRMs and that evangelists will want to be incarnational in their approaches. Using historical accounts and biblical basis, these top missiologists present their methodology and practical advice for reaching out to groups such as the Latter-day Saints, New Age, New Spirituality, Wicca, Mother Goddess, and Satanism.
