Come to Me, all you who labor and are heavily burdened, and I will give you rest.
The opposite of work is not play, it's rest. Consider the Sabbath your own personal "Opposite Day." As Matthew 11:28 reminds us, we are given the Sabbath as a gift from God. We're commanded to stop work and rest. Honor God, and do yourself a favor; make the Sabbath a day different from all others.
