The Importance of Marriage Partnerships

In 2 Corinthians 6, Paul issues severe warning against a Christian and a non-Christian now entering into marriage. That seems to be the Christian version of the Jewish endogamy. In 1 Peter as well, where advice is given to wives who may be Christians whose husbands are not believers,. And in 1 Corinthians 7, Paul doesn't say you should quit. But there's sometimes in some marriages comes a point where the unbelieving partner says, I can't be doing a few Christians.
