"Did not Christ Himself, addressing His disciples, utter these words: 'I have yet many things to say unto you, but ye cannot bear them now. Howbeit when He, the Spirit of Truth, is come, He will guide you into all truth'? From ... the words of Christ, as attested by the Gospel, every unprejudiced observer will readily apprehend the magnitude of the Faith which Bahá'u'lláh has revealed, and recognize the staggering weight of the claim He has advanced... Ours is the duty to ponder these things in our heart, to strive to widen our vision, and to deepen our comprehension of this Cause, and to arise, resolutely and unreservedly, to play our part, however small, in this greatest drama of the world's spiritual history."
(Shoghi Effendi, "The World Order of Baha'u'llah," p. 25)
