1 Masters, treat your bondservants justly and fairly, knowing that you also have a Master in heaven. 2 Continue steadfastly in prayer, being watchful in it with thanksgiving. 3 At the same time, pray also for us, that God may open to us a door for the word, to declare the mystery of Christ, on account of which I am in prison— 4 that I may make it clear, which is how I ought to speak. 5 Walk in wisdom toward outsiders, making the best use of the time. 6 Let your speech always be gracious, seasoned with salt, so that you may know how you ought to answer each person.

The word master has fallen out of use – rightly so because of its deplorable connotations from the era of American slavery. But, it is a biblical word that we should use regarding our Christ. He bids us call Him Master:

13 You call me Teacher and Lord (Master), and you are right, for so I am. 14 If I then, your Lord and Teacher, have washed your feet, you also ought to wash one another’s feet. 15 For I have given you an example, that you also should do just as I have done to you. ~ John 13:13–15

Paul reminds the Colossians that we have a Master in heaven.  He is the one who washed our feet and He commands us to do the same.  Authority can only be a blessing if you are able to serve “under” those in your charge and never “over” them – that’s the deal in Christ. 

10 the twenty-four elders fall down before him who is seated on the throne and worship him who lives forever and ever. They cast their crowns before the throne, saying, 11 “Worthy are you, our Lord and God, to receive glory and honor and power, for you created all things, and by your will they existed and were created.” ~Revelation 4:10–11
