First published in 1993, William Sloane Coffin's 
A Passion for the Possible presents a vision for the future that challenges assumptions and deepens our understanding of the importance of social justice and change.  Coffin deals with social issues that continue to face U.S. churches--abortion, sexism, homophobia, racism, poverty, the environment, and nuclear disarmament.  This second edition adds Coffin's powerful sermon preached after September 11, 2001, and a foreword  by Martin Marty.
