I highly recommend the article “Physical Work, Spiritual Health,” by Dr. J. Matthew Sleeth.
Here’s an excerpt:
All honest work can be done for the glory of God. As time passes and we grow in our understanding of God and the uniqueness of this planet, we reject more and more “laborsaving” machines. There is an old saying: If you are troubled, chop wood and carry water. This is wise advice. If you pray at the same time, so much the better. Begin to build an hour of work into your daily life. The result will be more life in your day. The flip side of work is rest. God commands all of us to take a day of rest each week, but how many of us take His advice?
