Focusing on Heaven rather than material things on Earth

Slate.com had an interesting article earlier this week about Pop-Culture Christianity. Christians are supposed to eschew the things of this world and keep their focus on Heaven (storing up their treasure there), but now they've created their own parallel universe where's there's a Christian counterpart to most secular things (Christian rock, for example). Is that the right way to go? Here's an excerpt from the article:

"In the '80s, Christians were known as the boycotters, refusing to see movies or buy products that offended them. They felt about commercial culture much the way a Marxist might: that it was a decadent glorification of money and meaningless human relationships. Then, sometime during the '90s, when conservative evangelicals started coming out of their shells, they took a different tack. The boycotters became co-opters and embarked on the curious quest to enlist America's crassest material culture in the service of spiritual growth....

At this point in history, American evangelicals resemble the Israelites at various dangerous moments in the Old Testament: They are blending into the surrounding heathen culture, and having ever more trouble figuring out where it ends and they begin. In politics, and in business, they've mostly gone ahead and joined the existing networks. With pop culture, they've instead created their own enormous "parallel universe," as Daniel Radosh calls it in his rich exploration of the realm, Rapture Ready! A Christian can now buy books, movies, music—and anything else lowbrow to middlebrow—tailor-made for his or her sensibilities. Worried that American popular culture leads people—and especially teenagers—astray, the Christian version is designed to satisfy all the same needs in a cleaner form."
