Colossians 3:22 admonishes, “Slaves, in all things obey those who are your masters on earth, not with external service, as those who merely please men, but with sincerity of heart, fearing the Lord.” It is interesting that the two words in this verse for the ones we are serving are the same:
When he refers to “your masters on earth”, the word “masters” there is from the Greek word “kurios” — which is the very same word employed in the singular in the expression “fearing the Lord” at the end of the verse.
So the lesson is clear: when we work, we are not to see ourselves as serving the earthly “lords”, but THE Lord, the God of heaven. We are not just to work hard when our boss is watching (the phrase “external service” is literally “eye service” — serving just when someone is watching!) but as Christians we are to work from our hearts, for God, ALL the time.
Perhaps this is a needed reminder for you as you go to work today. You are not merely working for that employer; you are working for the glory of God. Do what you do for HIM, not them. You are not serving “lords”, but THE Lord!
