In some Christian circles today there is a huge emphasis on the demonic realm and “deliverance” ministries.
There are books written, sermons preached, conferences attended and spiritual away weekends devoted to the subject.
TB Joshua was a so-called prophet of God in Nigeria. A large part of his ministry was exorcism. This “man of God” laid his hands on the faithful and rebuked the demons. There was the usual vomiting, crying and falling. He exorcised the demons of alcoholism, depression, poverty, sickness and whatever other bad spirit you may have unknowingly had.
I was in a car accident when I was 10 years old and as a result walk with a bit of a limp. A few years ago a well-meaning Christian asked if he could pray for me. I agreed as prayer is always a good thing. However, in his prayers he attempted to rebuke the Spirit of infirmity in me and demand my healing from God. I stopped him mid-prayer and said thanks but no thanks.
