Caught on camera

In reaction to Francis Chan's recently claim that he healed some people, it's striking to see cessationists like Justin Peters and Fred Butler invent a new standard for accepting a reported miracle: it must be caught on camera! If we take that seriously, as if plain old eyewitness testimony is untrustworthy, that instantly impugns the credibility of all biblical miracles. 

I'd add, at the risk of stating the obvious, that not all medical conditions are visible to a cellphone camera. Deafness is invisible. Many diseases are invisible, or only detectable via scanning internal anatomy, or lab work. 

Furthermore, unless they were expecting a miracle, there's no reason they'd have cameras running in advance to capture the event as it happened. 

Finally, if you're going to be that skeptical, it's also possible to fabricate photographic evidence.
