[M]any Christians assume the gospel . . . but are passionate about something on the relative periphery: abortion, poverty, forms of worship, cultural decay, ecology, overpopulation, pornography, family breakdown, and much more. By labeling these complex issues 'relatively peripheral' I open myself to attack from as many quarters as there are subjects on the list. For example, some of those whose every thought is shaded green will not be convinced that the ecological problems we face are peripheral to human survival. But I remain quite unrepentant. From a biblical-theological perspective, these challenges, as serious as they are, are reflections of the still deeper problem - our odious alienation from God. If we tackle these problems without tackling what is central, we are merely playing around with symptoms. . . . [W]hat does it profit us to save the world from smog and damn our own souls?
