Tosafot Yom Tov
AS YOU WERE CREATED FOR THIS PURPOSE. For the sake of this you came into the world, as per the verse “and there was evening, and there was morning, on the sixth day” (Genesis 1:31), which the Talmud expounds (Shabbat 88a): this teaches that G-d stipulated with Creation that should Israel not accept the Torah, the world will return to chaos. So it turns out that he has a tremendous responsibility and is not doing this as a favor—Rashi.
