Rav Yisroel Reisman gave a remarkable Shiur over a decade ago entitled “A Sense of History.” As I recall, his main point was that we would live our lives differently if we knew the historical significance of the choices we make. A simple example is Shemiras Shabbos, which, as we all know, was an incredible Nisayon in the earlier part of the previous century. To be sure, we cannot judge those who succumbed to this test, and there is no reason to believe that most of us would have fared any better. But one thing is certain: The success of Yiddishkeit in America today is, in no small part, thanks to the Mesiras Nefesh of those who were Omed b’Nisayon, and kept Shabbos under the most trying circumstances. Those who keep Shabbos today (which is relatively easy, with the advent of the five-day workweek) are, for the most part, descendants of those who kept Shabbos under the most trying circumstances. Rabbi Reisman wondered how many people realized that their decision would have long-term ramifications for their descendants, and for all of Klal Yisrael, and if such realization would have deterred many from throwing in the towel.
Rabbosai, it’s the same with the Nisayon of our generation. Our decision to do whatever it takes to remain clean, one day at a time, will have long-term ramifications for our descendants l’Dorei Doros, and for Klal Yisroel as a whole. Even if we can't succeed for ourselves, we must make sure to succeed for the future of Klal Yisrael.
