Eph. 6:7 Work with enthusiasm, as though you were working for the Lord rather than for people.
I worked for many years, mostly in factories. It is safe to say that very few people that I worked with worked with enthusiasm. Most people worked out of necessity and did not have a good attitude about their work. They did their jobs and eagerly went home. Their hearts were not at their work and often it showed in how much they worked, the quality of their work, and their attitude while working.
For the believer, it should not be that way. We should be setting an example for the world when it comes to what we do, how we do it, why we do it, and our attitude while we do it. I understand that very few people see their work as exciting and a good part of their day, but we should see things differently than the world. We should be thankful for the jobs we have and the abilities we have to do them. We should thank the Lord that we have health to work. We should be thankful that we live in a place where we can work for ourselves and our families instead of forced labor for others. We should consider our work to be opportunities to share Christ with non-believers. We should strive to show the world what a difference Christ makes in us through how we work and our attitudes about it.
As believers, we need to do all we do for the Lord and not for man. When we are driven by trying to please people we will always fall short. When we strive to please the Lord, it affects all we do. We need to see Him as worthy of our best efforts. We owe Him everything and our lives need to reflect it.
