This story just goes to show once again, you can't be born a Christian. You must be born again. We have no idea what was really going on with any of these people, but God knows. And He will comfort the afflicted and afflict the comfortable.
Being a Christian has nothing to do with being mentally ill. Mental illness is in fact a real illness and needs real medical treatment. I firmly believe people who say “he just needed “Jesus” or “to be born again” have no clue how bad a mental illness is or can get.
Let me put it to you this way, the mind is far gone the person can not comprehend Jesus or what it really means to be “born again”. I have seen this.
