Christians may certainly live in the suburbs, but they may not live suburban lives. Because, like any other social context, the suburban lifestyle is driven by a mad pantheon of subtle idols. Any suburbanite whose life has been shaped by the Gospel will seem… well… radical! His flourishing does not look like the flourishing of his neighbors.
