My father-in-law keeps telling me that somewhere in the Bible it says that at the end of time the doctors will not know what they are healing. Can you tell me if this is in the Bible and if so where I might find it?
Since your father-in-law claims that it is in the Bible, I wonder why he doesn't produce the verse? As presented, I know of no verse that even comes close to matching the statement. I've looked for verses that might be misapplied or twisted in some fashion to come to this conclusion and I can't think of one either.
