“For 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.”
1 Corinthians 7:14 (KJV)
Context Reading
12But to the rest speak I, not the Lord: If any brother hath a wife that believeth not, and she be pleased to dwell with him, let him not put her away. 13And the woman which hath an husband that believeth not, and if he be pleased to dwell with her, let her not leave him. 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?
