1 Corinthians 7:18

14For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband: else were your children unclean; but now are they holy.

15But if the unbelieving depart, let him depart. A brother or a sister is not under bondage in such cases: but God hath called us to peace.

16For what knowest thou, O wife, whether thou shalt save thy husband? or how knowest thou, O man, whether thou shalt save thy wife?

17But as God hath distributed to every man, as the Lord hath called every one, so let him walk. And so ordain I in all churches.

18Is any man called being circumcised? let him not become uncircumcised. Is any called in uncircumcision? let him not be circumcised.

19Circumcision is nothing, and uncircumcision is nothing, but the keeping of the commandments of God.

20Let every man abide in the same calling wherein he was called.

21Art thou called being a servant? care not for it: but if thou mayest be made free, use it rather.

22For he that is called in the Lord, being a servant, is the Lord’s freeman: likewise also he that is called, being free, is Christ’s servant.
