Unlike the Dispensation of Christ, unlike the Dispensation of Muhammad, unlike all the Dispensations of the past, the apostles of Bahá’u’lláh in every land, wherever they labor and toil, have before them in clear, in unequivocal and emphatic language, all the laws, the regulations, the principles, the institutions, the guidance, they require for the prosecution and consummation of their task. Both in the administrative provisions of the Bahá’í Dispensation, and in the matter of succession, as embodied in the twin institutions of the House of Justice and of the Guardianship, the followers of Bahá’u’lláh can summon to their aid such irrefutable evidences of Divine Guidance that none can resist, that none can belittle or ignore. Therein lies the distinguishing feature of the Bahá’í Revelation. Therein lies the strength of the unity of the Faith, of the validity of a Revelation that claims not to destroy or belittle previous Revelations, but to connect, unify, and fulfill them. This is the reason why Bahá’u’lláh and ‘Abdu’l-Bahá have both revealed and even insisted upon certain details in connection with the Divine Economy which they have bequeathed to us, their followers. This is why such an emphasis has been placed in their Will and Testament upon the powers and prerogatives of the ministers of their Faith.
