1 Corinthians 7:20-22

20 Each one should remain in the situation he was in when he was called.

21 Were you a slave when you were called? Do not let it concern you, but if you can gain your freedom, take the opportunity.

22 For he who was a slave when he was called by the Lord is the Lord’s freedman. Conversely, he who was a free man when he was called is Christ’s slave.
