Charles H. Kraft, a creative missiologist, spent over forty years teaching in the School of Intercultural Studies (formerly School of World Mission) at Fuller Seminary. After serving as a pioneer missionary in northern Nigeria, he became a pioneer in incarnational ministry and spiritual warfare. His scholarship, biblical basis, and international ministry have resulted in publishing a dozen books focusing on listening, loving, and serving those under evil spiritual influences and giving them tools to overcome as they develop a Bible-based Christianity that meets their needs.
