I hate to be the bearer of bad news, but sometimes God may mean for us to go through a/the struggle or fight with them, etc, so He may not always take it away, even in Jesus name, etc, and it's not always because the person did not have enough faith either, or wasn't doing it right either, as if there is a magical formula to it on our part, etc.
A very good and very close friend of mine was sent over to my house because he was going crazy one time/night, and was having very, very severe visual hallucinations of some messed up clowns that he thought were attacking him, etc. At his house, he tore through/up it with a big machete trying to attack them, or defend himself so he said afterward, and he actually did quite a bit of damage to the place in the process, and even went outside in his yard a couple of times, and up and down his street doing it, etc, and they (the people concerned about him) (and a little bit afraid of him) always seem to always think that's a special case for me to handle always, and so I did, etc. He was calling on Jesus name left and right, and using Jesus name a lot, and none of it worked. It was sad to watch, etc. Anyway, I got him to get some sleep finally, and took care of him for a few days, etc, and as he rested, ate, and slept, and was around me, and was talking with me, etc, he eventually started to calm down, and they started to go away, etc.
And in my situation, I'm not sure that I want my struggles with quote/unquote "voices" to completely go away. I have gained certain abilities and things through my struggles that are "priceless", etc, so I don't know if it's God's will for them to go away, since they have aided greatly in my ability to serve Him, and serve Himvery, very well, etc. I recall Paul and his "thorn in his side", etc, that the Bible is very, very clear about it being an angel of Satan, or aka, a powerful or high ranking demon, etc, that God basically told Paul that he was going to have to deal with if he (Paul) wanted to be used of God in the way that Paul wished, etc.
And besides this, I really don't think that calling on Jesus name in a crowd of people, or in a church, is going to make all of them just physically shut up physically and all just magically go silent right away, since my problems are with the actual noises and voices around me, and they say that it's a problem in my brain, etc, or so they say, etc, and I like to let people make up their own mind about that, etc.
Anyway,
God Bless.
