"... this priceless gem of Divine Revelation, now still in its embryonic state, shall evolve within the shell of His law, and shall forge ahead, undivided and unimpaired, till it embraces the whole of mankind. Only those who have already recognized the supreme station of Bahá’u’lláh, only those whose hearts have been touched by His love, and have become familiar with the potency of His spirit, can adequately appreciate the value of this Divine Economy—His inestimable gift to mankind. 
- Shoghi Effendi  (From a letter dated 21 March 1930, published in ‘The World Order of Baha’u’llah’)
