 Please understand this fact. Rest is not an option for us. It is a requirement. We all know people who burn the candle at both ends, and we know that sooner or later a crash is coming. Rest is so important for us that God gave us a commandment, remember the Sabbath day and keep it holy. Sabbath means rest. And so we have a command to cease work, to take a holiday. Jesus also said that the Sabbath was made for man, not man for the Sabbath.
