I'm an electrical engineer turned Bible teacher and theologian. I hope that's not shocking. I served 34 years at Moody Bible Institute, most of that time as chair of theology. I was pushed into the study of the spirit world not only by my own interest but by the many calls from people with questions. They asked about Bible teaching on Angels, Satan, and demons. Some needed counseling because of spirit manifestations and oppression. Out of my years of teaching I wrote a textbook used in colleges and seminaries, "Angels, Elect and Evil." The book "Demon Possession and the Christian," born out of biblical study and my experience as a counselor,
caused many to reevaluate their understanding of how demons can affect believers.
My latest book, "Winning the War through Prayer" gets very pointed with biblical basis for aggressive prayer and specific prayer patterns for countering forces of evil and allowing the Holy Spirit to protect and cultivate our lives.
I have counseled over 650 persons with demonic problems for over 46 years. I have seen the Lord Jesus free Christians from oppression and lead them into a life of fellowship and victory. The principles of acceptance with God, access to God, and authority in Christ can be applied to gain freedom and joy.
