Note: If you, or the person wanting demons/devils/unclean spirits cast out is not a born-again Christian, the Bible gives an example of what may happen here:
Acts: 13-18”13 ¶ Then certain of the vagabond Jews, exorcists, took upon them to call over them which had evil spirits the name of the Lord Jesus, saying, We adjure you by Jesus whom Paul preacheth. 14 And there were seven sons of one Sceva, a Jew, and chief of the priests, which did so. 15 And the evil spirit answered and said, Jesus I know, and Paul I know; but who are ye? 16 And the man in whom the evil spirit was leaped on them, and overcame them, and prevailed against them, so that they fled out of that house naked and wounded. 17 And this was known to all the Jews and Greeks also dwelling at Ephesus; and fear fell on them all, and the name of the Lord Jesus was magnified. 18 And many that believed came, and confessed, and shewed their deeds. “
I do not believe that you are a Christian, and so recommend strongly that you do not attempt this. You do not wish to run out of your house naked and bleeding, I am sure.
Because I am challenging your false doctrine?
Be at ease, I'm not offended ... I have been relegated to the "merely religious" many time by those in your creed.
If nothing else, this scariest verse in the Bible should give you pause ... and force you to seriously consider repenting from false doctrine. You have gone way beyond the text in your imagination.
Matt. 7:22-23
22 Many will say to Me on that day, 'Lord, Lord, did we not prophecy in Your name, and in Your name cast out demons, and in Your name perform many miracles?"
23 And then I will declare to them, 'I never knew you; depart from me, you who practice lawlessness.'
