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.
