My point of this was none of the healed were said to have unrepentant sin they would not get away from. Also in many cases the prayer is point specific prayer. Praying about unforgiveness getting rid of soul ties and the like.
I do agree with one point, but I do not think it is about demons, it is about releasing spiritual authority from the Lord.
Many times people have been in situations in a church were they have felt badly about a fellow christian and wondered why the Lord has not worked in their life. Only after they repented did they see release in the other persons life.
I agree that if you have obvious sin in you life that you do not repent of, this blocks the Lord moving and doing things in you. But I would not connect that with demons, but with obvious spiritual reality.
And yes you do need special training and help dealing with these cases, but that is not because of the demons involved, you are talking massive trauma and disclocated emotions, personality etc. I suggest you are talking in some regard to super spiritually, and not at a simple, this takes years to grow through, and some will be scared for the whole lives, unless miraculously healed. Also mental illness is involved, and often drugs etc. which are never going to make things easy.
I had a friend who dealt with alcoholics and mentally ill people and it drove him to a nervous breakdown because he got too involved, and could not see the difference between being played and helping someone see reality.
But I also know from have a relative with mental illness, few understand the total emotional trauma this creates when you are with someone you love, and it all sounds so sensible, but it always ends in an insane place with emotional panic.
So bear with us, because most do not know even the reference points.
