On Sunday June 14, 2002, Rev. William Barber III gave a 43-minute sermon to an empty Washington National Cathedral. He integrated events from American history to provide a context for his message: “America, accepting death is not an option anymore.”

One example of his literalness: In America you can find unleaded gas anywhere, but also cities where there is no unleaded water.
His use of historical facts provides a picture of America that was not part of any course I took. Be inspired.
