Now, friends, I'm not telling this from some kind of a psychologic. I have dealt with demons for years, and you know that. If you only knew the thing, after the services is over at night, what goes on sometimes. You don't know. Remember, when you come against a spirit, you better know what you're speaking about. Just don't stand there and carry on, 'cause it ain't going to do any good. But when actually a demon has to obey you, he'll recognize it. It ain't how loud you holler; it ain't how much oil you put on. It's what's back here that he'll recognize. It's the truth. Jesus just said to him, "Come out."
