Hmm, faith is just the basics at which things work. It is not THE thing that prevents demons coming back.
The question is why did they ever enter someone?? Sin is a reason. Another reason is negative feelings or thoughts. The more someone exercises these negative thoughts or sin, that will open doors for demons to enter. Same thing with drugs, smoking, excessive eating or drinking. In basic words: anything you do not have under control might open doors.
Faith will not prevent demons from entering. There is a passage in the bible that talks about the strong man (Matt 12:29, Mark Mark 3:27, and Luke Luke 11:21-22.). The solution is to have God fill every empty spot in you. Some might think, didn't I already give myself to God. Is my body not God's temple. Well, talk aint the same as giving as a sacrifice in whole. The moment you told the world, demons, angels and God himself that you belong to Jesus and He is your Lord is THE beginning. It is not the finish! The reason is that your spirit man was reborn, but your thoughts and feelings are still the old. That's why the bible says about nailing yourself to the cross.
Nailing yourself to the cross, is , what I think a continues, lifelong action that is always in the present tense. Because sometimes we think or feel to go back to the old ways.
As long someone did not let the old ways of thinking or feeling go, they are all open doors for demons. Or they make it easy for demons to use you as a target practise. Target practise? if you ever talk to prophetic people in Christ, they sometimes see arrows sticking into you. That means, you were negative, or sinning, etc, that lowers your protection.
Examples:
- Anger for someone , you cannot explain it why you are angry at all sometimes.
- Lust for any girl or man
- Love for money
- Excessive eating or drinking
- keep using drugs, smoking, etc and cannot get rid of it.
- feeling a looser always
- thinking you know everything and your the best (devil did that ,and how he fell!)
- (extreme ) fear for people, situations, possbile future problems, etc
Why above list? Every negative thing or thing that is not good for your body has a named demon after it. Just read the bible. So by doing things that are not good for you, you are actually inviting them and kicking God away in certain parts in your temple. (temple is your flash body, thinking, feelings etc).
I was talking about lowering your protection. How???
Bible talks about the armor of Christ. Shield of faith. That is only one part! You need the whole armor! Otherwise arrors from the devil to hurt you keep hitting you and will stick. Read about Gods armor (
Ephesians 6:10-18
)
Yeah they go elsewhere, the bible says that when they're cast out sometimes they try to go back to their old host. So if you're getting delivered...make sure your faith is super strong -- because those d3moms will try to com3 back and if theyre able to get in....they'll come back stronger. So you have to have strong faith and be able to defend yourself against them when they try to come back.
They also search for other people to inhabit as well, its all very creepy.. That's why its good to have God living on the inside.
