1 Corinthians 7:18-20
7:18 Was anyone called after he had been circumcised? He should not try to undo his circumcision. Was anyone called who is uncircumcised? He should not get circumcised.
7:19 Circumcision is nothing and uncircumcision is nothing. Instead, keeping God’s commandments is what counts.
7:20 Let each one remain in that situation in life in which he was called.
