Check out the first chapter of Wallis' new book, available by download at Sojourners website: Rediscovering Values.
All of us need to act and re-act appropriately if we truly do want the Change that was promised us by Pres. Obama. This isn't a one person play, but a drama with every one of us on the stage, acting in partnership with one another, or in opposition to each other to aggrandize ourselves. Serving, not hoarding and accumulating, is the only way out of this recession.
I believe that the answer to Wallis' question is YES! "So do Christians have a responsibility to turn over the tables of an unjust market?" (p.20)
