Book excerpt: Based on eight years of hands-on experience and more than 300 interviews, Street Saints is both a book of motivational stories about unsung heroes and a sociological study of the "faith factor," documenting faith-based programs that are treating social maladies in America. This book takes readers on a tour of communities and institutions in America where faith-based initiatives are making a difference. It offers inspiration, role models, and guidelines for people who would like to give back to their own communities.
