1 Corinthians 7:19-21

19 For circumcision is nothing and counts for nothing, neither does uncircumcision, but [what counts is] keeping the commandments of God.

20 Everyone should remain after God calls him in the station or condition of life in which the summons found him.

21 Were you a slave when you were called? Do not let that trouble you. But if you are able to gain your freedom, avail yourself of the opportunity.
