You’re probably familiar on some level or another with the various observances and customs associated with celebrating a Bar Mitzvah; putting on tefillin, getting called to the Torah for an Aliyah and possibly even reading from the Torah. You may not be familiar with the Chabad custom of reciting a Chassidic discourse. This means that in addition to the responsibility of preparing the Torah portion there is also the added preparation needed to be able to recite (from memory) the entire discourse. One of the basic ideas that is contained in that discourse is the concept of Hashem fulfilling all the Mitzvahs that we have been given to observe. Here’s an interesting question - if Hashem fulfills all the mItzvahs of the Torah, then how could Hashem destroy the Temple? This Sunday is the date on which we annually commemorate the destruction of the Holy Temple in Jerusalem (in the year 69). We fast for the entire 24+ hours, we say extra prayers and we look forward to the time that Hashem will rebuild the Temple. But the question is - how could it be that Hashem would violate one of His own laws? You see, the Torah prohibits the Temple’s destruction. The Torah explicitly instructs the Jewish people that upon entering the Holy Land they’d have to destroy all remnants of the rampant idol worship that had been predominant. The Torah then continues, “You shall not do this (i.e. destroy or desecrate a place of worship) to Hashem your G-d.” Which means that there exists an actual biblical prohibition against destroying (even a part of) the Holy Temple. And just as we are obligated by law to respect the Temple and not destroy it, so too Hashem is bound by that Mitzvah. Well, if that’s the case, what’s Hashem’s excuse? How could He destroy the Temple? How could He allow its destruction? There can only be one conclusion (and in fact this is alluded to in many verses); that the destruction was not the final purpose, it was a step in the process of ultimately rebuilding the Holy Temple. This then explains how it’s possible for Hashem to destroy the Holy Temple - because the destruction is not the goal, the rebuilding is. And if someone is destroying something in order to rebuild it in a greater and more impressive manner, in that case the destruction itself is considered part of the process of rebuilding. This all sounds nice perhaps, but what practical difference does it make? The Temple was still destroyed and it is still not rebuilt. The legal reasoning how Hashem “is allowed” to do so doesn’t change the facts on the ground!? Or does it? The understanding that this process of destruction is actually part of a greater rebuilding (in addition to helping to make the experience that much more bearable), allows us to realize our ability to complete the process and bring complete redemption to this world.
