"Enjoy life with the woman whom you love all the days of your fleeting life which He has given to you under the sun; for this is your reward in life and in your toil in which you have labored under the sun. Whatever your hand finds to do, do it with all your might; for there is no activity or planning or knowledge or wisdom in Sheol where you are going." (Ec 9:9-10 NAS95)
"Whatever you do, do your work heartily, as for the Lord rather than for men, knowing that from the Lord you will receive the reward of the inheritance. It is the Lord Christ whom you serve." (Col 3:23-24 NAS95)
By training, I am an electrical engineer. My present earthly occupation by which I earn a living for my family is operations & construction manager for an electric utility. Like most work, it is filled with challenges, enjoyments, and frustrations--but never boredom! My role is to lead and organize a group of electric line workers, along with their supervisors and administrative help, to build and maintain a power system in the Shenandoah Valley. We also must restore service when power goes out (due to weather, people, or objects hitting or cutting lines, etc.). Never a dull moment.
The important thing to remember is to both: (1) work heartily as for the Lord, glorifying Him by the way I do my work and carry my attitude, and (2) realize that this work is temporal, not getting wrapped up in it for its own sake, and looking forward to being with the Lord for eternity. Maintain that balanced perspective.
