Having a Sabbath rest is not the same as taking a nap. A Sabbath rest is a time during which spiritual learning and enrichment are enhanced, and are preferred over physical learning. A Sabbath rest is a time of intense worship, celebration, and acknowledgement of the power of God.
The Lord God Almighty has decreed that it also shall be a time of physical respite for those in the kingdom who have worked the hardest, and have contributed the most toward establishing the kingdom. The Lord God Almighty reigns.
The Lord God Almighty El Shaddai
