Moshe symbolizes the power of a human being overcoming his nature. That’s why it says: וַיַאֲ מִׁ ינוֵּ בֵַה'ֵוּבְ משֶ הֵ עַ בְ דוֵֵֹידֵ לא they believed in Moshe; i.e., we have to believe in the power a human being to overcome his nature. And that’s why Moshe was the one to do all the Nissim, because when you become a Melech over yourself and your personal weaknesses, then you get the power to overcome the Tevah (nature) of the world. The Chovos Halvavos says that Tevah (the forces of nature) become your servants when you are on top of yourself, like Rabbi Pinchos ben Yair who split the River Gi'noi (Gemara) and Daniel to whom the lions were like gentle puppies. He refrained from eating Treife royal meat, and was a major: ב ֵגֵַתְֵמִֵׁרֵ עֵַלֵ יִֵׁצְֵרוֹ (person who overcame his Yetzer Hara). That’s what Moshe teaches us; i.e., that by overcoming his Yetzer Hara a human “creates” himself, and in this way, he is like Hashem, the Creator of the world.
We are leaving Mitzrayim: בְ יָדֵרָ מָ ה with a high hand, i.e., the ability to conquer our Yetzer and meet the challenges of the world. People who fight, stay young. R’ Nosson Wachtfogel Zatzal says that’s why people enjoy competitive sports, because a human needs to fight. Kids in my class say that they’d rather play a game even if they lose, rather than sitting around doing nothing. In the Heim they said: People who don’t fight are like “floating dead fish”. And those that fight the Yetzer Hara are the happiest people in the world.
