1 Corinthians 7:15-20

15(But if the husband or wife who isn’t a believer insists on leaving, let them go. In such cases the believing husband or wife is no longer bound to the other, for God has called you to live in peace.)

16Don’t you wives realize that your husbands might be saved because of you? And don’t you husbands realize that your wives might be saved because of you?

17Each of you should continue to live in whatever situation the Lord has placed you, and remain as you were when God first called you. This is my rule for all the churches.

18For instance, a man who was circumcised before he became a believer should not try to reverse it. And the man who was uncircumcised when he became a believer should not be circumcised now.

19For it makes no difference whether or not a man has been circumcised. The important thing is to keep God’s commandments.

20Yes, each of you should remain as you were when God called you.
