Steve H,
Why would you think it to be likely? What about people with the same diagnoses who aren’t prayed for and go into spontaneous remission in any case? What if I was told that someone had a terminal diagnosis so slaughtered a goat at midnight, ran backwards three times round a maypole and sang Ricky Martin’s “Livin’ la Vida Loca” at the top of my voice and the person concerned recovered?
Would it be likely that these actions had effected the cure? If not, why not?
