"Our life together can be better." That's the opening sentence of an important new book by Jim Wallis called On God's Side: What Religion Forgets and Politics Hasn't Learned About Serving the Common Good. Wallis wrote it while taking a three-month sabbatical last year, in the midst of the 2012 election -- a break that allowed him to get a broader perspective on what was going on in American public life. The book draws inspiration from Abraham Lincoln's famous line: "[M]y concern is not whether God is on our side; my greatest concern is to be on God's side..." For Wallis, the key to being on God's side is a focus on the common good. But, as Wallis saw vividly during his sabbatical, that doesn't seem to be the direction things are currently headed in our country. Instead of strengthening our commitment to equality, social justice, and our sense of unity as a nation, our public and political discourse is breaking us apart.
