They are written by Charles H. (Chuck) Kraft who is "retired from the faculty of the School of Intercultural Studies at Fuller Seminary (formerly the School of World Mission) after 40 years as professor of anthropology and intercultural communication. He taught anthropology, communication, contextualization, and spiritual dynamics (inner healing, deliverance, and spiritual warfare) to missionaries and prospective missionaries.
He holds degrees from Wheaton College (BA anthropology), Ashland Theological Seminary (BD theology), and Hartford Seminary Foundation (PhD anthropological linguistics). He served as a pioneer missionary among a tribal group (Kamwe/Higi) in northeastern Nigeria for three years followed by five years each on the faculties of Michigan State University and UCLA, teaching linguistics and African languages.
He is the author of more than 30 books and numerous articles in the fields of his expertise. He spends most of his time now ministering to those with emotional and spiritual problems and conducting deep healing (inner healing) seminars in churches worldwide. He has been used by God to lead thousands to spiritual and emotional freedom in Jesus Christ."
Thus what he writes is well researched and well written. I am working through two books so far -
Defeating Dark Angels// and
Deep Wounds, Deep Healing.
