The Jews are a royal nation and are expected to act with nobility. Moshe Rabeinu (Moses) and the generation of the midbar (desert) experienced a blinding revelation of G-d on Har Sinai (Mount Sinai). The Jews living in Eretz Yisroel, under the kingdom of Dovid Hamelech (King David), experienced a limited level of kedusha (holiness). The Ba’al Shem Tov taught us how to find sparks of holiness in a galus (exile) that seems completely devoid of holiness. We all experience different levels of holiness within ourselves at different times.
