People have all manner of slogans and bumper stickers by which they express a certain work ethic or disposition toward work. Some are humorous, others are pathetic, but they all reveal an attitude toward work which hardly becomes the Christian.
Work exercises body or mind.
God blessed us with minds, and bodies to cart them around in. Part of our stewardship of these gifts is to strive for strength and health of body and mind. This makes a good place to note that if our work is strong in one dimension of exercise, we ought to discipline ourselves to exercise ourselves in the other dimension. In other words, those whose work primarily exercises their body should find ways to exercise their mind as well. And if your occupation mostly occupies your mind, then make times for exercising your body.
