Although the exodus took place thousands of years ago, it has significance for each one of us to this day. At the time of the exodus, we received our “spiritual eyes,” namely, the ability to perceive that the world does not consist only of what we sense in the physical plane.

In truth, the main purpose of the exodus from Egypt was for us to have faith in the existence of miracles. Chiefly, this means recognizing the spiritual side of creation, and knowing that creation is not merely that which one sees with his eyes, nor that which he feels with his bodily senses. The physical matter that we see constitutes only the outer garment of true creation. What is true creation? It is the spiritual force behind the physical world. (Rabbi Yeruĥam Levovitz, Da’at Torah, Exodus, p. 95)

The miracles of the exodus made it apparent that the Jewish people have a unique role in the world, and that the entire world was created for them. The miracles served a dual purpose; they provided both proof that God is the Creator of the world, and proof that the world was created for the Jewish people.

God altered nature for the children of Israel at the exodus from Egypt [for example, with the ten plagues and the splitting of the sea]. This was proof with regard to the Creator, that is, that He is the Creator and He acts in accordance with His will [and can even alter the course of nature if that is His will]. In addition, it was proof with regard to the children of Israel that the entire world was created for them; this is why God altered nature for them. Indeed, God could have redeemed us in accordance with the laws of nature, but the whole purpose of the exile in Egypt and the redemption from there was to make it clear that God would alter His world for the Jewish people. (Rabbi Yehuda Aryeh Leib Alter, Sefat Emet, Bo 5649)
