I would suggest you take a course in Bible interpretation. Pay attention when it comes to types/anti-types and prophecy. There is a pattern to events that is not always obvious to the casual reader/observer. In other words similar events happen in different ages for the same reasons. History repeats itself. Therefore we get "There is no new thing under the sun". So the warning to the early Churches was valid to them but also to the Churches in subsequent ages which fit the same traits and characteristics. Therefore the studious and alert can be forewarned of upcoming events and be prepared.
OK, so tell me was the Bible written to us, or for us? Furthermore, if a prophecy was fulfilled why look for it to be again?
Well said.
Likewise...
"And the Lord said, Who then is that faithful and wise steward, whom his lord shall make ruler over his household, to give them their portion of meat in due season? Blessed is that servant, whom his lord when he cometh shall find so doing." (Luke 12:42,43)
