I'm still agnostic. But in the words of Elton Richards, I'm now a reverant agnostic. Which isn't an oxymoron, I swear. I now believe that whether or not there's a God, there is such a thing as sacredness. Life is sacred. The Sabbath can be a sacred day. Prayer can be a sacred ritual. There is something transcendent, beyond the everyday. It's possible that humans created this sacredness ourselves, but that doesn't take away from its power or importance.
This is what the Sabbath should feel like. A pause. Not just a minor pause, but a major pause. Not just lowering the volume, but a muting. As the famous rabbi Abraham Joshua Heschel put it, the Sabbath is a sanctuary in time.
