We have been weaned on the idea that the Torah and Its Mitzvot are the means to uplifting the individual Jew who performs them, and that he ultimately receives reward for his decisions and merits the all-spiritual afterlife.
While this is true, the deeper truth is that the Torah and Its Mitzvot are the guidelines to revealing God in the physical world by Am Yisrael. While it is certainly true that any individual who follows in the way of God will ultimately merit the all-spiritual afterlife, the greater truth is that by following the way of God we can realize and reveal God in all aspects of this world – the entire world can be “a fraction of an example of the World to Come” (see, for example, Midrash Tanchuma Tetzaveh 13).
This is indeed the most exulted thing of all.
