It hath been decreed by Us that the Word of God, and all the
potentialities thereof, shall be manifested unto men in strict conformity with
such conditions as have been foreordained by Him Who is the All-Knowing, the
All-Wise.... Should the Word be allowed to release suddenly all the energies
latent within it, no man could sustain the weight of so mighty a Revelation.
(Baha’u’llah, quoted by Shoghi Effendi in ‘The Promised Day Is Come’)
