None of this, of course, is appealing to romantic young people who want to be boldly called to something larger than their own self interest. For this reason, we have seen the decline of mainline churches in America coincide with the rise of Christianity in other (less welcoming) parts of the world. And for this reason, I suspect, we have seen more and more young Christians checking out of politics.

That’s why the loss of the culture war is an opportunity rather than a crisis. It is in times like these — when there is a stark cleavage between the world and believers — that Christianity typically grows and rediscovers its purpose.

Just as political parties wrestle with whether or not it’s better to be a big tent, or (to paraphrase Reagan) to fly “a banner of no pale pastels, but bold colors,” there is an argument that “nominal” Christians cause more problems than solutions. In politics, numbers matter, of course, and Christians who are still looking for a political savior may view this trend as bad news. But for Christians focused on something more transcendent — saving souls and winning real converts — there is a silver lining to losing the culture.
