1 Corinthians 7:16-18

New International Version - UK

¹⁶ How do you know, wife, whether you will save your husband? Or, how do you know, husband, whether you will save your wife?

Concerning change of status

¹⁷ Nevertheless, each person should live as a believer in whatever situation the Lord has assigned to them, just as God has called them. This is the rule I lay down in all the churches. ¹⁸ Was a man already circumcised when he was called? He should not become uncircumcised. Was a man uncircumcised when he was called? He should not be circumcised.
