22 For the one who was a slave when called to faith in the Lord is the Lord's freed person; similarly, the one who was free when called is Christ's slave.
English Standard Version
22 For he who was called in the Lord as a slave is a freedman of the Lord. Likewise he who was free when called is a slave of Christ.
22 I'm simply trying to point out that under your new Master you're going to experience a marvelous freedom you would never have dreamed of. On the other hand, if you were free when Christ called you, you'll experience a delightful "enslavement to God" you would never have dreamed of.
New King James Version
22 For he who is called in the Lord while a slave is the Lord's freedman. Likewise he who is called while free is Christ's slave.
New Living Translation
22 And remember, if you were a slave when the Lord called you, you are now free in the Lord. And if you were free when the Lord called you, you are now a slave of Christ.
The rules of Christianity reach every condition; and in every state a man may live so as to be a credit to it. It is the duty of every Christian to be content with his lot, and to conduct himself in his rank and place as becomes a Christian. Our comfort and happiness depend on what we are to Christ, not what we are in the world. No man should think to make his faith or religion, an argument to break through any natural or civil obligations. He should quietly and contentedly abide in the condition in which he is placed by Divine Providence.
