Nauti,
I saw this same dad with his daughter a few years ago being interviewed by a news station. I can say from personal experience, although what they do is real, I'm extremely hesitant to their methods that they use. I spearhead our deliverance ministry team here in Taylorsville NC and although we lead people through prayers (with permission from the individual) and command spirits to leave and go into the abyss, we do it as best as we can believe that Jesus did it during his time here on Earth. (With a loving and gentle approach)
The second thing is at no time does our team think "we" are doing anything. Jesus is the healer, he is the one that sets the captives free, not us. We just lovingly pray with people and walk them through binding prayers all the while coming out of agreement with the enemy. Lastly, I do know many people that do this as a full time ministry that do earn income from it, however I nor my team accept a penny. I am not trying to insinuate that I am any better than someone that does accept love offerings, but my feelings are that the Lord set me free from my captives of many years and I want to reciprocate (never trying to earn Grace through works) to the Lord the same love he extended to me.
The biggest reward I receive is seeing people smile and say, "I have never felt so good in my life", or witnessing the Lord giving them an infilling of Peace that only He can give and they weep with such love. It is a precious and Holy sight to witness, and the Children's bread is one of the most loving gifts Jesus came to give to all of us. True freedom in Jesus Christ.
Thank you for the post Nauti and have a Blessed weekend.
Greg
