1 Corinthians 7:17

But as God hath distributed to every man, as the Lord hath called every one, so let him walk. I have said this much about the marriage of an unbeliever with a believer, and about separation and divorce, if the unbeliever seek for it, and about living together in peace; but I do not wish to be understood to mean that a divorce is to be sought for, or that peace is to be broken, merely through lust and a desire to change one's state, as, e.g., that a believer, because he is a believer and called to Christian liberty, may desire and find an excuse for changing his servile condition into one of freedom, his position as a Gentile into that if a Jew. I ordain, therefore, that each one of the faithful, whether he be a Jew or a Gentile, bond or free, maintain the state and condition which the Lord has given him, and which he had before he became a believer. Let each one walk in his own line; let him be content with that, and live as becometh a Christian; let him not grow restless to change his state because of his Christianity, and so cause the Gentiles to stumble.
