After we learned how to do deliverance on each other, God had us do it on ourselves. It helps to know the exact name of the demon you are casting out, but it isn’t necessary. Sometimes it’s a guessing game, and you can guess based on past experience, what type of demon is in you. So far in my experience, they tend to come out of a persons mouth, we’d just say something (with faith) like, “I repent of X”, or “X, I cast you out in Jesus name!” Usually I can go with a pretty long list of names in my head and some of them will be hits and some misses, I guess it’s the shotgun approach. The first time I did it on myself I went through a long list of demon powers, and I remember vomiting out a spirit of anti Christ I had from an atheist stage in my life. More recently I had to cough of a spirit of X (not naming it) which was taking residence in my brain and after that I had a bad head ache for a while. These things can only take up residence in you and stay there if they have legal ground, but if they don’t have legal ground they can be cast out, although they’d rather just hide in you and go undetected after they have lost legal ground. These things (spirits of the air, demons, evil spirits) can also alter a humans behavior, their goal is to drag humanity into so much sin that they cannot be cast out, or they remain hidden and cause the person to misbehave at strategic points of a persons life, and they try to make it look like they are just part of that persons ‘personality’. Also, if you sincerely repent these things lose legal ground.
Something that almost tripped me up was thinking I was doing it under my own power, when it was really Jesus who cast them out, it’s a mental trap. Even though it requires your own faith, you cannot cast these things out by your own power, you have to be clear that it is Jesus casting out the things.
When they are cast out, sometimes they make a weird noise, like a scream, a mans voice, or some other demonic vocalization.
Just want you to know that self deliverance is possible! 🙂 The easiest way is to talk to the evil spirit within a person saying, X, I cast you out in the name of Jesus! Look into Derek Prince or Win Worely on how to cast out evil spirits.
