We have a mitzvah of sipur yetzias Mitzrayim (telling the story of the exodus from Egypt) on Seder night. This obligation is learned from pesukim in this week’s parsha. Aside from retelling the story, there are many acts that we do to focus us on the story of Yetzias Mitzrayim. In doing so, the Chinuch tells us that we strengthen our emunah.
אדם נפעל כפי פעולותיו.(Chinuch 16)
(A person is motivated through the actions that he does).
The Hafla’a expands on this mitzvah, and brings us to an understanding of the pesukim (Shemos 10:1-2):
כִּי אֲנִי הִכְבַּדְתִּי אֶת לִבּוֹ (I have hardened his heart) לְמַעַן תְּסַפֵּר (in order that you should be able to retell the story).
The reason for hardening Paro’s heart was not just to intensify the punishment which he rightfully deserved, but also in order to make the grandeur of the miracle even more spectacular, giving us more to speak about. With this he explains the answer to the wicked son (the Rasha) that if one does not expound on leil haseder, he would not merit to go out of Mitzrayim, for the purpose of yetzias Mitzrayim and the merit that our forefathers had to leave Mitzrayim was because we were going to retell the story every year. In other words, retelling the story today is not only a mitzvah in its own right that gives us emunah, but our retelling also is what gave our forbearers the merit to be redeemed 3000 years ago.
As we learn the parsha this week, and contemplate the wonders that happened, we should urge ourselves to broaden our understanding of the miracles in order to have a greater effect on the yetzias Mitzrayim of long ago, and naturally as our own emunah strengthens we should merit that Hakadosh Baruch Hu bring about our own redemption today.
