There is a time for work and there is a time for rest and recreation. We can dishonor God by working without rest or exercise just as much as we can by resting and exercising without working. The key to learning how to redeem the time is learning how to hold every activity of life in proper proportion, to know what is appropriate for what occasion, and to do it all to the glory of the triune God.
