Demons are Real

Yes, I believe in their existence.  I'm writing this short post because not long ago I came across a fascinating account concerning demonic activity and Dr. Daniel B. Wallace, one of the premiere biblical manuscript authorities alive today.  What makes it even more interesting to me is where he teaches; Dallas Theological Seminary hardly could be called a hotbed for continualist thought.  Consider this:
Several years ago, Dr. Daniel B. Wallace (’74) — a Biola graduate and professor of New Testament at Dallas Theological Seminary — was asked to perform a house exorcism. The wealthy Christian homeowner reported poltergeist phenomena that began when his father moved in. As Wallace and a colleague prayed through the rooms, objects began to move, according to Wallace. 
“It was small objects, like magnets on the refrigerator flying clear across the room. It was really remarkable,” said Wallace, who once doubted that demonic activity occurs today. He’s now writing a book arguing that many evangelicals have become unbiblically antisupernatural.
I wish I could find a more complete account of this exorcism.  You may wish to read his article, "Who's Afraid of the Holy Spirit?"  He also helped compile a book of the same title.

Wallace isn't the only Dallas teacher to delve into the demonic realm.  Dr. Merrill Unger was a published writer on the subject.  I just found this snippet fascinating, having come from the noted koine Greek expert.
