Now consider, in this great century which is the cycle of
Bahá’u’lláh, what progress science and knowledge have made, how many secrets of
existence have been discovered, how many great inventions have been brought to
light and are day by day multiplying in number. Before long, material science
and learning, as well as the knowledge of God, will make such progress and will
show forth such wonders that the beholders will be amazed. Then the mystery of
this verse in Isaiah, “For the earth shall be full of the knowledge of the
Lord,” will be completely evident.
