The world with the various calamities ...

"The world with the various calamities that have befallen it, will be completely ravaged and its civilization demolished, if the Baha'is do not come to its help and embue it with the spirit that Baha'u'llah has brought to the world. The economic factions, political parties, national hatreds, racial prejudices, and religious antagonisms, will continue to bring about devastating wars until the spirit of the Cause permeates the heart of man, and its universal teachings pull down the existing barriers. Let us be reminded of our duty by the misery we see around us, and arise for the prosecution of our noble duty."
 From a letter dated 24 November 1931 written on behalf of Shoghi Effendi to the American National Spiritual Assembly.
