On the fourth day of creation, God created the great luminaries of the sky. The sun and moon not only serve essential roles in the sustainability of the universe, but they can also teach important life lessons. The sun is a constant source of light and energy. Everyday without fail, the same fiery ball appears in the sky above. The moon on the other hand, is characteristically very different. The moon is constantly changing and appears slightly different each time it rises throughout the month. At some points in the month, the moon is full, round, and luminous. At other points in the month, the moon appears as a tiny, silver crescent. Even when the moon seems to have completely disappeared, it renews and regrows itself once again. Even in times of trial and tribulation when the Jewish people are facing dire situations, they maintain their faith in God and are always renewed.
