Tell me, what would you say is the primary thing that has influenced your views on this? I don't mean necessarily a preacher or teacher, I mean what life experiences or theological viewpoints most strongly color why you believe that demonic activity is often overplayed by many Christians? Give specific instances or people that effected your view on it.
I was introduced to the theories of C. Peter Wagner and Chuck Pierce back in the 80's. I believe it was just after C. Peter left Fuller Theological Seminary. I had a number of interactions with Fuller because of a church growth series they produced. (Good Series BTW).
It was the late 80's / early 90's that C.Peter spearheaded the warfare movement, I know I read his book "Warfare Prayer" around that time and the growth of "Warring in Tongues" became widely popular in some circles.
My pastor at the time was very much involved with Randall Terry and the early Pro Life movement. He made getting arrested like a badge of honor. We gathered as a group, perhaps 20 or so and went to war on his behalf because he was facing charges as an habitual offender (which he was) - some were praying angry prayers in tongues at the top of their lungs - screaming into the heavenliness - others were binding a variety of demons - still others were pulling down strong holds - (their words, not mine)
The next day the judge threw my pastor in jail for 11 months.
I remember wondering with all the hours of prayer and all the energy and fervency - why didn't it work? What went wrong? In the months he was incarcerated we prayed nightly for him, that his angels would protect him and as before binding the devil, warring tongues, pulling down strongholds etc. as before.
His 11 month sentence became almost two years as additional charges were racked up on him. The church, once 2,200 strong dissolved to less than 300 and then completely closed.
It wasn't until I read "Territorial Spirits" a number of years later that I began to question the whole Spiritual Warfare teachings.
I read after Ron Philips and a couple other authors who do not come to mind right now.
My journey continued when I started studying Theology. Foundations of Pentecostal Theology by McDuff and VanCleaf is very well written, as is Bible Doctrine: a Pentecostal Perspective by Menzies and Horton.
Along with a couple Angelology courses, it gives a pretty well rounded view (IMHO) of demons and satan.
As I learned exegesis techniques my main influence was Scripture itself and the Holy Spirit.
I remember praying for a group of "Prayer Warriors" and asking God to bless them and hearing Him say those at war are always at war and can see nothing but the fight. They are fighting the war I won 2,000 and have given up peace to continue what is already won.
Then I started experiencing it in the ministry. Casting out demons has been part of my ministry - certainly not a majority - but a part still the same.
Hope that answers your question. Thanks for asking.
