Still, the data from nearly every survey suggest that young Americans want to get married. Eventually. That makes sense. Our Creator clearly intended for male and female to be knit together in covenantal relationship. An increasing number of men and women, however, aren’t marrying. They want to. But it’s not happening. And yet in surveying this scene, many Christians continue to perceive a sexual crisis, not a marital one. We buy, read, and pass along books about battling our sexual urges, when in fact we are battling them far longer than we were meant to. How did we misdiagnose this?

The answer is pretty straightforward: While our sexual ideals have remained biblical and thus rooted in marriage, our ideas about marriage have changed significantly. For all the heated talk and contested referendums about defending marriage against attempts to legally redefine it, the church has already ceded plenty of intellectual ground in its marriage-mindedness. Christian practical ethics about marriage—not the ones expounded on in books, but the ones we actually exhibit—have become a nebulous hodgepodge of pragmatic norms and romantic imperatives, few of which resemble anything biblical.
