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.
