In a style that is immediately scholarly yet accessible, Aikman examines the commonly held belief particularly by evangelicals, that America is no longer a "Christian nation." Citing conflicts of religious freedom and discussing the history of American Christianity from the nation's inception up through the turbulent 1960s, Aikman proves that America has, in fact, declined in its cultural and political values that were once rooted in Christian principles. Instead of despairing, he ends the book with reasons for hope, reminding Christians that their religion thrives and grows most when faced with a hostile opposing culture. Dramatic increase of evangelical conviction and engagement in secular cities such as Seattle and Manhattan point to an unprecedented urban revival pioneered by prominent writer and pastor Timothy Keller and flamboyantly masculine Mark Driscoll. Informative, understandable, and hopeful, One Nation Without God? will educate, concern, but ultimately mobilize American Christians to remember the nation's faith-based roots and to resist the pull of secularization whose ideas are often dehumanizing and destructive.
