Great civilizational moments in history are always cosmic — not only political and military but moral, spiritual, and theological too. They become total contests between the kingdom of God and the forces of darkness in different times. Today, however, Christian faith in the West is becoming ever more spiritual and private in the face of its growing rejection in public. In the US, too many are divided between an overly ‘privatised’ faith and an overly ‘politicized’ faith, so that the Christain faith in America is increasingly marginalised and irrelevant. Together with the global churches around the world, the American church should be poised to make a historic contribution to the future of humanity.
