Do Demons exist?

Do Demons exist?

I'm just addressing my comments to those that dont believe Demons exist. There are at least two books that are worth reading. One is M. Scott Pecks book , "People of the Lie". The other that is worth reading is Malachi Martins , " Hostage to the Devil". Hostage to the Devil is out of print I believe but is available on Amazon.com. Scott Peck is a psychiatrist who investigated whether Possession by the Devil is real. "People of the Lie" details his investigations. "Hostage to the Devil" details the sucessful exorcism of 5 Americans.I also bring your attention to the following Blog.

It was written by Joseph Edward Duncan III prior to his arrest for murder and kidnapping: One excerpt from his entry "Wrestling with Demons":"The current battle is of epic proportions (I do not make this claim idly either). It is a battle between me and my demons. Only two people in the world have a clue as to the power and nature of my demons (besides me) and they will probably never read this. But just the same, these demons are stronger than even I gave them credit for, and now they are taking my best blows and not even staggering. I’m afraid, very afraid"

Also the Riverside Press Enterprise did a story on July 8, 2005 quoting BTK Killer Dennis Rader,"I just know its a dark side of me. It kind of controls me. I personally think it' a --- and I know its not very Christian---but I actually think its a demon thats within me."

Still think Demons dont exist?
