Shabbat is an island in time, a day of rest in the rush of activity that engulfs the other six days of the weekly cycle. For 25 hours -- from sundown Friday evening to nightfall Saturday night -- we cease all creative involvement with our surroundings, transcend the worries and struggles of our daily existence, and enjoy the divine tranquility of G‑d's day of rest.
We all know the story of how G‑d created the world in six days and rested on the seventh. But creation was not a one time event. It is an ongoing process: G‑d is continually creating our world in a cosmic cycle of work and rest. By resting on Shabbat, we bring our own lives in sync with the divine cycle of creation. We attest to G‑d's creation of the world, affirm our own role as G‑d's "partners in creation," and bring wholeness, holiness and purpose into our lives.
