The short duration of His Dispensation, the restricted range within which His laws and ordinances have been made to operate, supply no criterion whatever wherewith to judge its Divine origin and to evaluate the potency of its message. “That so brief a span,” Bahá’u’lláh Himself explains, “should have separated this most mighty and wondrous Revelation from Mine own previous Manifestation, is a secret that no man can unravel and a mystery such as no mind can fathom. Its duration had been foreordained, and no man shall ever discover its reason unless and until he be informed of the contents of My Hidden Book.” “Behold,” Bahá’u’lláh further explains in the Kitáb-i-Badí’, one of His works refuting the arguments of the people of the Bayán, “behold, how immediately upon the completion of the ninth year of this wondrous, this most holy and merciful Dispensation, the requisite number of pure, of wholly consecrated and sanctified souls had been most secretly consummated.” The marvelous happenings that have heralded the advent of the Founder of the Bábí Dispensation, the dramatic circumstances of His own eventful life, the miraculous tragedy of His martyrdom, the magic of His influence exerted on the most eminent and powerful among His countrymen, to all of which every chapter of Nabíl’s stirring narrative testifies, should in themselves be regarded as sufficient evidence of the validity of His claim to so exalted a station among the Prophets. However graphic the record which the eminent chronicler of His life has transmitted to posterity, so luminous a narrative must pale before the glowing tribute paid to the Báb by the pen of Bahá’u’lláh. This tribute the Báb Himself has, by the clear assertion of His claim, abundantly supported, while the written testimonies of ‘Abdu’l-Bahá have powerfully reinforced its character and elucidated its meaning.
