Years ago I heard a joke about a seminary student taking a final exam. He was to take a half hour to write on Jesus Christ and a half hour on the Devil. At the end of the hour, the instructor came to pick up the papers, and notice the student had only written on Christ. The student looked up and said I got so involved with Jesus Christ I had no time for the Devil.
Now in one sense this is good theology, but I was watching David Jeremiah and his sermon today was "Identifying the Enemy" He started out by basically saying that in order to beat your enemy you need to know your enemy.
So the question is how much time do we give to study on the Devil in proportion to study on Christ?
Your post reminds me of a great pastor I had years ago in Florida. He was a wonderful man and very knowledgeable of the scriptures. Every Saturday we would go on visitation, and then it was our weekly habit to stop by a large Christian bookstore.
He would always go to the section about demonology and Satan. He would pick up various books and read a little. One day I asked him why, and he responded, "You have to know your enemy, but you have to be careful."
Just the way he said this kind of startled and frightened me. I asked him why you have to be careful. He said the devil likes to work incognito, he always works in the background. If you see a photo of very bad men, he is one in the background that most folks do not pay attention to. He said that if you point out the devil to others, this makes the devil VERY angry and he will come after you.
Well, I was young at the time, and this really frightened me. I asked him if the devil had ever come after him. He said yes, but he wouldn't tell me exactly how the devil came after him. He said you have to have a lot of faith to study this subject.
Well, I kind of made up my mind right there to stay away from this subject. I have heard of others who have had great difficulties after studying this subject, one pastor told me of a fellow student when he was in college that made a detailed study of Satan and demons, and this person literally lost their mind and had to be committed to a mental institution.
My 2 cents.
