> I can find a cholera outbreak, and tell whoever will listen to stop drinking water from the local wells ... Those who listen, even if only one, will be my proof.
Results with diseases have a fair amount of chance, as we should all know by now. It might go as you say, it might not. Your disciple might leave and get cholera soon after due to exposure beforehand. A person who stayed and didn't get cholera might attribute their success to the manner in which they prayed. Or your guy's success to the manner in which they prayed.
It's hard to falsify the assertion that "they were not stricken because they were righteous / said the correct prayer", and "statistical significance" is not a dramatic or obvious thing to convey.
