EXOD313 It is widely recognized that a man's obligation of service corresponds to the degree of favor bestowed upon him. In every generation there are events which occasion one people to be singled out from all other peoples for God's special favor. They, in turn, must distinguish themselves in the service of the Creator, May He be exalted, to a greater degree than all of the other peoples. But there is no way to know this by the intellect alone. For instance: God chose us by bringing us out of the land of Egypt, dividing the Red Sea, and the other favors which followed, which are too well known to be mentioned. [Correspondingly] the Creator, May He be exalted, singled us out from all other nations for service, which He bound us to so that we might express our thanks to Him. For accepting this service He promised us reward -- in this world and the next -- that is indescribable, a grace and a kindness from Him, made He be exalted. Now, all this becomes clear only through the Torah, as it says in Scripture: “You have seen what I did to Egypt, and how I carried you on eagles’ wings and brought you to Me. Now, if you listen carefully to My voice and keep My covenant, you will be for Me a special treasure among all the peoples, for all the earth is Mine. And you will be for Me a Kingdom of priests and a holy nation” (Shemos 19:4-6).
