We have lots of mitzvos that are zecher l’Yetziyas Mitzrayim, like tefillin, Shabbos etc. The Ramban explains the reason for this. At Yetziyas Mitzrayim, Hashem showed us that he made the world and is in charge of it. He can change nature at any given time, as He did at Yetziyas Mitzrayim. And from this, we can learn that in our own lives too, Hashem is the One in charge of everything. He watches over us all b’hashgacha pratis!
This is the most important part of all of the Torah, that we should know that all that happens to us is a nes from Hashem; tailor-made for us! This is why it is so important that we remember Yetziyas Mitzrayim so often.
