"That is to say, were ye to gather the works, the inventions, and the wonders of the previous five thousand years, they would by no means compare with those in this heavenly era and divine century. "

 

"O ye faithful friends of ‘Abdu’l-Bahá! In this new springtime, the luminous Orb shone forth from the vernal point at the equator, shedding its splendour upon the world and bestowing, through its light and heat, a new grace and a potent spirit upon every region. Through that heat and light, energy and vitality were generated in the veins and sinews of the world, a new creation was called into being, and a fresh spirit was breathed into it. The weary frame of the world was endued with new life, and the dead body of existence was quickened and endowed with measureless blessings. A wondrous Dispensation dawned, a new creation was called into being, and the verse “I breathed of My spirit into him” was fulfilled.⁷⁸ The realm of being was adorned, and the universe was illumined by the dawning of that manifest Light. Signs of life and growth appeared in all created things, and great advances became visible in all beings.

Those who judge with fairness acknowledge that the nineteenth century was the era of light and the pride of all ages. The signs of progress became visible in every aspect of existence, in such wise that it became equal to a hundred others. Indeed, the achievements of this one century were greater than those of the fifty that came before. That is to say, were ye to gather the works, the inventions, and the wonders of the previous five thousand years, they would by no means compare with those in this heavenly era and divine century. The enterprises and discoveries of those fifty centuries, their sciences and inventions, their achievements and wonders, cannot rival those of this one century."
