Book excerpt: New York Times bestseller God's Politics struck a chord with Americans disenchanted with how the Right had co-opted all talk about integrating religious values into our politics, and with the Left, who were mute on the subject. Jim Wallis argues that America's separation of church and state does not require banishing moral and religious values from the public square. God's Politics offers a vision for how to convert spiritual values into real social change and has started a grassroots movement to hold our political leaders accountable by incorporating our deepest convictions about war, poverty, racism, abortion, capital punishment, and other moral issues into our nation's public life. Who can change the political wind? Only we can.
