If you believe that that biblical prophecies are more symbolic than literal and none of them have relevence for the world today then there's not much to talk about. There's no common frame of reference. Thank you for the discussion.
I'm not sure what you mean by "relevence [sic] for the world today". The Bible is relevant for every person in every age. Many of the prophecies were directly fulfilled in Christ's first coming to the earth. But that fact does not make them irrelevant for us today. "Behold, the virgin shall be with child, and bear a Son, and they shall call His name Immanuel," which is translated, "God with us." That still has relevance, doesn't it?
My frame of reference comes from carefully comparing Scripture with Scripture to determine if a specific prophecy if fulfilled in the past or in the future. I do not automatically push the fulfillment of prophecies into the future based on some artifical "literal" method.
Likewise, I know that passover is no longer an options for Christians because I have carefully studied the person and work of Jesus Christ and see how that old covenant ordinance was merely a shadow of the good things to come. It was a type. Once the anti-type appeared (Jesus Christ), the type was no longer necessary.
I know that many pop prophecy preachers are sure that Christ is going to return in the next few years or so. I doubt they have enough savvy to be that certain with their prognostications.
