THAT is how Christians can and do have demons. Some demons are like computers. It is still on, but in a state that uses less power. You can trigger your hiding demon by something you do or say. Like a hibernating bear, when it is time for him to get up and eat, nothing will stop him.
Some demons are just like the bear.
Except for unplugging the printer, I have found no way to stop it dead in its tracks. I recently printed a document, not knowing how many pages there would be. It kept on going and going. Some have it downloaded, but it is not being used. Don't download the devil's software.
