1 Corinthians 7:12-24

But to the rest say I, not the Lord: If any brother hath an unbelieving wife, and she is content to dwell with him, let him not leave her. And the woman that hath an unbelieving husband, and he is content to dwell with her, let her not leave her husband. For the unbelieving husband is sanctified in the wife, and the unbelieving wife is sanctified in the brother: else were your children unclean; but now are they holy. Yet if the unbelieving departeth, let him depart: the brother or the sister is not under bondage in such cases: but God hath called us in peace. For how knowest thou, O wife, whether thou shalt save thy husband? or how knowest thou, O husband, whether thou shalt save thy wife? Only, as the Lord hath distributed to each man, as God hath called each, so let him walk. And so ordain I in all the churches. Was any man called being circumcised? let him not become uncircumcised. Hath any been called in uncircumcision? let him not be circumcised. Circumcision is nothing, and uncircumcision is nothing; but the keeping of the commandments of God. Let each man abide in that calling wherein he was called. Wast thou called being a bondservant? care not for it: nay, even if thou canst become free, use it rather. For he that was called in the Lord being a bondservant, is the Lord’s freedman: likewise he that was called being free, is Christ’s bondservant. Ye were bought with a price; become not bondservants of men. Brethren, let each man, wherein he was called, therein abide with God.
