If they were to do nothing else, the effects which Bahá’u’lláh’s life and writings have already had should command the earnest attention of anyone who believes that human nature is fundamentally spiritual and that the coming organization of our planet must be informed by this aspect of reality. The documentation lies open to general scrutiny. For the first time in history humanity has available a detailed and verifiable record of the birth of an independent religious system and of the life of its Founder. Equally accessible is the record of the response that the new faith has evoked, through the emergence of a global community which can already justly claim to represent a microcosm of the human race.
