I think it is very interesting to see how a man of God who walks with God has dominion over the demons that come through people seeking to destroy Him.
Sometimes when the power of God is moving strongly, unusual things are done. But the main principle is that Jesus is greater than any demon. Demons are liars. The Bible says that as believers we shall cast them out.
I hope this video will encourage you to believe that in submission to the LORD Jesus Christ you are more than a match for any evil power.
I also hope that people who have no experience in the matter and have not helped others get free of demons (or themselves) will first learn something practical before telling what they think they know.
