“And whatever you do, do it heartily, as to the Lord and not to men”
“as to the Lord”
When we do our work as unto the Lord, it sets it apart as eternal work. Our true boss is the Lord. We work for him. This gives our work eternal dignity. The Lord is the motivation for our service.
“and not to men”
God does not want us to serve our earthly boss exclusively.
God is our ultimate employer.
We do not do our job unto the Lord when we take miserable attitudes to work or make noises like we are unhappy with the boss and environment. We do not serve the Lord when we loaf when the boss is not looking. We do not serve the Lord when we undermine another employee to get him into trouble with his boss so that we can have his job. We want to move up, so we drop a little negative note about him into the suggestion box.
When the boss comes around, we patronize him. Licking the boots of the boss is not the best way to serve the Lord. Kicking people in the teeth below you is not the best way either! Scripture does not recommend these things!
If we keep God in view in everything we do at work, we honor God at our place of employment.
