Bondservants, obey in all things your masters according to the flesh, not with eyeservice, as men-pleasers, but in sincerity of heart, fearing God. And whatever you do, do it heartily, as to the Lord and not to men, knowing that from the Lord you will receive the reward of the inheritance; for you serve the Lord Christ. (Colossians 3:22-24)
Mediocrity is deplorable. Do your best, whatever good thing you do. Do not do your best only when others with authority over you are watching (remember, the Lord is always watching you). You are a servant of the Lord. This compels you to always give your all and do your best at every task you are given. Don’t just “do enough to get by” – Excel! Christians who were slaves were to be obedient, hard working and respectful to their masters. The same is true as an employee today. Though you are not a slave, you have agreed to do a day’s work for a day’s pay. So, do your work honestly and from your heart, without grumbling and complaining. Remember, you serve the Lord Christ; He will reward you by and by.
