Recent statistics have shown an increasing exodus of young people from churches, especially after they leave home and live on their own. In a 2007 study, Lifeway Research determined that 70% of young Protestant adults between 18-22 stop attending church regularly.

Increasingly, the "plan" has taken the form of a total image overhaul, where efforts are made to rebrand Christianity as hip, countercultural, relevant. As a result, in the early 2000s, we got something called "the emerging church"—a sort of postmodern stab at an evangelical reform movement. Perhaps because it was too "let's rethink everything" radical, it fizzled quickly. But the impulse behind it—to rehabilitate Christianity's image and make it "cool"—remains.

"Wannabe cool" Christianity also manifests itself as an obsession with being on the technological cutting edge. Churches like Central Christian in Las Vegas and Liquid Church in New Brunswick, N.J., for example, have online church services where people can have a worship experience at an "iCampus." Many other churches now encourage texting, Twitter and iPhone interaction with the pastor during their services.

But one of the most popular—and arguably most unseemly—methods of making Christianity hip is to make it shocking. What better way to appeal to younger generations than to push the envelope and go where no fundamentalist has gone before? Sex is a popular shock tactic. At the same time, many churches are finding creative ways to use sex-themed marketing gimmicks to lure people into church.

But are these gimmicks really going to bring young people back to church? Is this what people really come to church for? Maybe sex sermons and indie- rock worship music do help in getting people in the door, and maybe even in winning new converts. But what sort of Christianity are they being converted to?

If the evangelical Christian leadership thinks that "cool Christianity" is a sustainable path forward, they are severely mistaken. As a twentysomething, I can say with confidence that when it comes to church, we don't want cool as much as we want real.

If we are interested in Christianity in any sort of serious way, it is not because it's easy or trendy or popular. It's because Jesus himself is appealing, and what he says rings true. It's because the world we inhabit is utterly phony, ephemeral, narcissistic, image-obsessed and sex-drenched—and we want an alternative. It's not because we want more of the same.
