It seems a comfort to know that your friend didn’t appear afraid. I’m sure that was a gift to both of you that you were able to pray with her and remember that Jesus is more powerful than anything or anyone else in the universe.

Years ago I was asked, “Have you ever been personally aware of being in the presence of demons? Have you ever been aware of a guardian angel doing something on your behalf?”

Theologian G. C. Berkouwer said, “There can be no sound theology without a sound demonology.” Some deny the existence of demons, regarding them as mere symbols of man’s inhumanity to man. But even those who believe the Bible tend to develop sloppy demonology.

Primero, sabemos que los demonios no son omniscientes, ya que son solo ángeles, seres finitos creados; y los ángeles no conocen muchas cosas, incluyendo el tiempo del regreso de Cristo (Marcos 13: 32).

Question from a reader: I recently hosted a book club for Safely Home. Most people really enjoyed it, and it seemed to give everyone a lot of food for thought on Heaven. But the one complaint I heard several times was the part about the Buddhist monk who appears to be demon possessed. People said they felt it was too forced and bizarre. Can you give any insight as to where that scene comes from? Randy, did you know of a particular event like this?

A.W. Tozer (1897–1963) has been one of the great influences on my life since I was a new believer, as a teenager. I fed on Tozer as a young Christian, and still today God speaks to me through his writing.

At a book signing at Lifeway Christian Bookstore in Beaverton, Randy Alcorn answered a variety of questions. In this clip, he answers the question, "What have been your experiences with spiritual warfare?"

How should a Christian respond to mental illness? How do you determine if there is demon possession or if it is genuine mental illness, in which case, the person is still acting in sinful ways based upon biological problems. 

My good friend, seminary professor and theologian, Gerry Breshears, has written/compiled three different articles related to this subject. He has done extensive research and has firsthand experience in dealing with demon possession.
