Spiritual disciplines are the habits we keep that connect us to God. They come from the Jewish conviction that action shapes and reveals what we ultimately believe. Our faith might come and go, but our actions should never waiver. This can be true for people of all faith claims.
We dance in rhythm with God when we keep the Sabbath. The reason we are called to take a day of rest is simple. Humans tend to forget that we did not make the world and thus, that the world does not depend upon us.
