 It says, but if you're married to an unbeliever, man, you stick it out. Why? Because it says that that believing spouse sanctifies the unbeliever. Now, that does not mean that you as a Christian in a marriage where your spouse is an unchristian, that they get salvation by proxy. That's not what it means. But what it does mean is that you are there and that you can be the light that is needed in that person's life to bring them to Christ. And that ought to be your goal.
