If you wonder: “What will we eat in the seventh year if we don’t sow or gather our produce?” I will appoint My blessing for you in the sixth year, so that it will produce a crop sufficient for three years. – Leviticus 25:20-21
Within God’s economy there is such a thing as “necessary rest.” It is proscribed in the provision given above to the Israelites, but also (I believe) expected in the lives of those of us who follow the Son today.
While work is profitable … and expected … rest is profitable as well. “Necessary rest” is an opportunity to reflect on God’s provision (through our accumulated resources and the ability to accumulate resources) and give Him thanks. If we do not take time to rest (and reflect), we are prone to forget our Provider, grow in our perceived independence, and slip into idolatry.
It is necessary to rest.
A soul without reflection, like a foundation without inhabitant, to ruin runs. – Edward Young
