God designed our minds and bodies for work. When we are active mentally and physically, we are likely to feel our best. There is no intrinsic downside to work, as I see it. However, one who is undisciplined can burden himself with busyness without much real productivity. There is also the risk of such a one working hard, but neglecting other aspects of his stewardship (e.g., responsibility to family). In our era, however, there is more risk of one being lazy or distracted with the cares of the world than working himself to death with skewed priorities. Balance (self-discipline) is required, and let us remember that our true “rest” is yet to come.
