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. We have, moreover, ordained that its veil of concealment be none
other except its own Self. Such indeed is Our Power to achieve Our Purpose. 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. Nay, all that is in
heaven and on earth would flee in consternation before it.
(Baha'u'llah, ‘Gleanings
from the Writings of Baha'u'llah’)
