Well, folks, if you haven't picked up Sacred Marriage by Gary Thomas you absolutely should do so and do so right now. In fact, here's a link to it. Order it immediately. Then read it. And encourage your spouse to read it. Then read it again.
I've read it before and have recently reread it. It's so rich and wise and full of perspective when it comes to marriage. His point is in the subtitle: what if God intended marriage to make you holy rather than to make you happy?
I won't spoil the book, but let me just say that he interacts well with current culture as well as historical thought and does both in a way that's accessible. And it's really well written.
But the big thing is it is challenging. It will push you. And that's a good thing. Because marriage matters. And Jesus matters even more.
But that's just me thinking thoughts...
