Is There a Danger That a Demon That Has Just Been Cast Out Will Go into Another Person Who Is Present?
There is NO case in Scripture where this happened, and Jesus cast out a lot of demons. Jesus did not see this as a problem. He cast out demons publicly and He was obviously not concerned that a demon would enter someone else. This question is typical because so few people know much about what the Bible says about deliverance. Along with the areas of prayer and revival, I think the area of deliverance has some of the worst teaching in the Body of Christ. There are a LOT of weird ideas about deliverance that have no basis in the Bible, so you need to be careful what kind of teaching you listen to. The bad teaching actually magnifies Satan and demons.
This question assumes that demons have all kinds of power and can just enter a person at will. That might be the premise for a horror movie, but real demons need someone to yield to them. Scripture teaches not to give place to the devil – not to give him an opportunity (Ephesians 4:27). That means that it is up to you as an individual not to give an opportunity to the devil. If you don’t do something to give the devil an opportunity, he can’t get a foothold in your life. A demon can’t just break down your back door and barge in.
Now you may be thinking, “Yes, that’s true for a believer, who has authority over the devil, but what if there are unbelievers present, who are still under the sway of the wicked one? Aren’t they in danger?” Apparently, Jesus didn’t think so, because not a single person in the crowds to which He ministered was born again and had authority over the devil the way that we do! They were ALL unbelievers, yet there is no indication of a demon jumping into someone else in the crowd, requiring Jesus to minister deliverance to the second person.
In case you’re wondering, YES, I’ve read the popular cartoon tract where a demon leaves one person and enters another, but I get my theology from the Bible, not from cartoon tracts.
So I am totally unconcerned about this issue, and I consider it safe to say that you don’t have to worry about it either. I have NEVER seen anything like this happen myself.
