20 Everyone must remain in the condition of life where he was called.
21 You were a slave when you were called? Never mind. Of course, if you do find it possible to get free, you had better avail yourself of the opportunity.
22 But a slave who is called to be in the Lord is a freedman of the Lord. Just as a free man who is called is a slave of Christ
23 (for you were bought for a price; you must not turn slaves to any man).
24 Brothers, everyone must remain with God in the condition of life where he was called.
