Book excerpt: Evangelicals today probably have more political influence in the United States than at any time in the last century--but they might not be certain what to do with it. It has been difficult to develop a unified voice on pressing issues such as social justice and moral renewal. Bestselling author and theologian Ron Sider offers a biblically grounded, factually rooted, Christian approach to politics that cuts across ideological divides. Shaped by a careful study of society, this book will guide readers into more thoughtful and effective political activity. It addresses perennially tough questions that often divide the church and includes a case study of the federal deficit debate. Practical, balanced, and nonpartisan, this book will be a welcome resource during the 2012 presidential race. This is a revised version of what was previously published as The Scandal of Evangelical Politics.
