Os Guinness, in his outstanding new book Fools’ Talk: Recovering the Art of Christian Persuasion, page 139:
The foundational assumption is always the same. Whatever anyone claims is the truth over against God’s view of truth, the real truth is still the truth, always the truth, and it points toward its Creator. We are therefore homesick for truth, and through the signals of transcendence the whole of creation is inviting us to think of its Creator—and ours. Inevitably and inescapably, then, all who will not hear the signals, and all who hear them but refuse to follow them, condemn themselves to be restless. This is already the chronic state of unbelievers in the fallen world, but the problem is made worse under the conditions of the advanced modern world, and especially in the world of consumerism and its disordered desires. For a consumer society thrives by stoking unquenchable desires into unsustainable cravings and fanning them with an inflated rage for rights. The restlessness it creates by providing false satisfactions and deadening true desires simultaneously fuels the economy and destroys happiness.
