1 Corinthians 7:15-20

15But if the unbelieving partner separates, let it be so. In such cases the brother or sister is not enslaved. God has called you to peace.

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

17Only let each person lead the life that the Lord has assigned to him, and to which God has called him. This is my rule in all the churches.

18Was anyone at the time of his call already circumcised? Let him not seek to remove the marks of circumcision. Was anyone at the time of his call uncircumcised? Let him not seek circumcision.

19For neither circumcision counts for anything nor uncircumcision, but keeping the commandments of God.

20Each one should remain in the condition in which he was called.
