Rabbi Jacobson answered that Rabbi Meir’s opinion teaches us an extremely important idea. This idea grants us perspective on world events and everything that transpires in our lives.
If we would read a newspaper report of the events described in the early chapters of Megilas Esther - “Achashverosh was king over many countries, he threw a party with extraordinary culinary delights, drinks, and grand décor...” - we would consider it nothing more than current affairs or political machinations.
Rabbi Meir is teaching us that this is a mistake. The megila does not begin with the salvation nor with the tzaros; it begins long beforehand with a litany of seemingly unrelated events.
This complex and amazing tapestry of occurrences were woven together for the sake of Klal Yisrael. All of Achashverosh’s acts and the myriad of occurrences of that period, were pieces of a grand jigsaw puzzle that had important impact on Klal Yisrael’s salvation many years later.
This has been true throughout our history. The Vilna Gaon would say that if we only saw the full picture of our lives, we would each be able to write an entire megila, no less than Megilas Esther.
This is why the megila will remain forever, even as the other parts of Nach become batul. Its fundamental lessons remain relevant to each person, throughout history.
In fact, one might even say that the megila will become more relevant in the times of Mashiach. In those times we will see the complete master plan of the history of Klal Yisrael.
We will understand each instance of tzadik v’ra lo, rasha v’tov lo, and why we experienced difficulties and tragedy. Every part of our lives will be revealed to be part of a huge masterplan. Megilas Esther is a microcosm of this idea - a prelude to Mashiach. It will thus never become batul - it is the first page in the sefer of l’asid lavo.
