Rev. Jim Wallis, Author, Activist And Sojourners Founder, On Religion, Politics And Finding Common Ground (VIDEO)

"Our life together can be better."

That's the message in Rev. Jim Wallis' latest book, 'On God's Side: What Religion Forgets and Politics Hasn't Learned About Serving the Common Good.'

Wallis, who is the founder and president of the faith-based social justice organization Sojourners, sat down with HuffPost's Dan Koh at last week's Aspen Ideas Festival to discuss the idea that politics has become a game of winning and losing, and it's up to the people to start finding common ground.

"Politics can't fix itself unless there are social movements from outside that enable politics to do the right thing," he said in the interview.

He gave the example of 'Bibles, Badges & Business,' a collaborative effort by the faith community, law enforcement and corporate leaders to drive immigration reform in Congress. The alliance helped achieve a monumental bipartisan vote on border security last month.

He also spoke of his mission to reach the "none of the aboves" -- the people who cite 'none of the above' as their religious affiliation, despite a belief in God.

"This book I wrote really is to the 'nones,' you know, the 'none of the aboves' who want their lives to make a difference. And if they're people of faith they want their faith to make a difference. And I think making a difference in the world is what brings us together."

Wallis also discussed belief and the new generation, political cynicism, and his personal definition of success in the full interview above.
