Already in the land where the greatest battles of the Faith have been fought, and its most rapacious enemies have lived, the march of events, the slow yet steady infiltration of its ideals, and the fulfillment of its prophecies, have resulted not only in disarming and in transforming the character of some of its most redoubtable enemies, but also in securing their firm and unreserved allegiance to its Founders. So complete a transformation, so startling a reversal of attitude, can only be effected if that chosen vehicle which is designed to carry the Message of Bahá’u’lláh to the hungry, the restless, and unshepherded multitudes is itself thoroughly cleansed from the defilements which it seeks to remove.
