The desire of marketers and emergents to engage the culture is commendable. Engaging it, though, is not the same thing as capitulating to it. Missionaries know the difference. They know they can adapt to local dress and blend in by learning the language and by fitting in with the accepted rhythms of daily life. They can understand the fears and hopes of those they serve without actually embracing those hopes and fears themselves. However, the day they accept the worldview of those they work among, it is time to go home. They have nothing to say anymore.
If the evangelical church does not want to lose its voice, it will have to ensure that its engagement with postmodern culture is done biblically, thoughtfully, and conscientiously.
They church must remember two points in particular: first, that Christianity is about truth, and second, that those who say they are Christians must model this truth by their integrity. A world without truth, postmoderns know, is an empty and dangerous place. And in a world full of hype and spin, manipulation and posturing, personal integrity is like a precious jewel. Even a little integrity goes so much further than all the technology, the country-club churches, and the big performers that can be mustered in the propagation of the biblical gospel. [Page 92]
