For nearly half a century, Jim Wallis has been at the forefront of the conversation about the Gospel and social justice. We talk to him about his life, his work, and his new book, America's Original Sin.

Listen to the interview here.

In the new book, Wallis offers a prophetic and deeply personal call to action in overcoming the racism so ingrained in American society. He speaks candidly to Christians--particularly white Christians--urging them to cross a new bridge toward racial justice and healing.

Wallis is the founder of the Sojourners community in Washington, DC, and is the editor-in-chief of the magazine of the same name. He is a New York Times bestselling author, witha dozen books to his name. His most recent book is the newly-released America's Original Sin: Racism, White Privilege, and the Bridge to a New America.

In February 2016, Wallis will embark on a multi-city book tour, which will include commuity events and conversations designed to engage local leaders in dialogue and coalition-building.
