Just like Nostrodamus, applying prophecy to past events is easy. All you have to do is manipulate obscure references to mean whatever you want.
lol But it is
so much more than that so it is impossible for that objection to stand.
Babylon, Israel, the European Union, etc., were held by some prophecy scholars as literal for centuries but they were scoffed at by the world and even allegorist prophecy scholars and preterists. Even Hal Lindsey in the 70's taught that Russia and China would rise as a military powers. After the Cold War ended, other prophecy scholars labeled him a false teacher and demanded a public apology from him. He refused and told them to just watch- this is what the Bible says will happen and it
will happen. Sure enough, here it all comes. Russia and China are rising at an alarming rate. The E.U. was also something that was foreseen.
Another example would be prophecy scholars were baffled for years how on earth 'the entire world' could witness the death of the two witnesses in Jerusalem. With satellite and television, this is now possible for the first time in history. Then prophecy scholars warned of a conflict between Iran, Syria, and Israel. This seem inevitable to us today but all of this was warned of prior to Israel's rebirth of 1948.
Etc.
ad nauseum. The prophecies were known and we know what to look for. The next thing we have our eyes on is the conflict between Israel, Russia, and the Muslim coalition. Not far fetched now but we've been waiting for decades.
You're objections are very understandable, not to mention common. In these types of discussions, the general objections always comes down to:
1). The prophecies were self-fulfilled.
2). The prophecies were written after the fact (pretty hard to believe considering even the newest books of the Bible are almost 2,000 years old lol).
3). The prophecies are so vague, they are fulfilled in hindsight.
However when a person studies, and I mean truly studies, the objections will become more and more absurd to that person. It's pretty fascinating.
