The world's equilibrium hath been upset through the vibrating influence of this most great, this new World Order. Mankind's ordered life hath been revolutionized through the agency of this unique, this wondrous System -- the like of which mortal eyes have never witnessed.

this new World Order
In the Persian Bayán, the Báb stated: "Well is it with him who fixeth his gaze upon the Order of Bahá'u'lláh, and rendereth thanks unto his Lord. For He will assuredly be made manifest. God hath indeed irrevocably ordained it in the Bayán." Shoghi Effendi identifies this "Order" with the System Bahá'u'lláh envisages in the Aqdas, in which He testifies to its revolutionizing effect on the life of humanity and reveals the laws and principles which govern its operation.
The features of the "new World Order" are delineated in the Writings of Bahá'u'lláh and 'Abdu'l-Bahá and in the letters of Shoghi Effendi and the Universal House of Justice. The institutions of the present-day Bahá'í Administrative Order, which constitute the "structural basis" of Bahá'u'lláh's World Order, will mature and evolve into the Bahá'í World Commonwealth. In this regard, Shoghi Effendi affirms that the Administrative Order "will, as its component parts, its organic institutions, begin to function with efficiency and vigour, assert its claim and demonstrate its capacity to be regarded not only as the nucleus but the very pattern of the New World Order destined to embrace in the fullness of time the whole of mankind".
For additional information on the evolution of this new World Order, see, for example, the letters of Shoghi Effendi published in The World Order of Bahá'u'lláh.

We have appointed two signs for the coming of age of the human race
The first sign of the coming of age of humanity referred to in the Writings of Bahá'u'lláh is the emergence of a science which is described as that "divine philosophy" which will include the discovery of a radical approach to the transmutation of elements. This is an indication of the splendours of the future stupendous expansion of knowledge.
Concerning the "second" sign which Bahá'u'lláh indicates to have been revealed in the Kitáb-i-Aqdas, Shoghi Effendi states that Bahá'u'lláh, ". . . in His Most Holy Book, has enjoined the selection of a single language and the adoption of a common script for all on earth to use, an injunction which, when carried out, would, as He Himself affirms in that Book, be one of the signs of the 'coming of age of the human race'".
Further insight into this process of mankind's coming of age and proceeding to maturity is provided by the following statement of Bahá'u'lláh:

One of the signs of the maturity of the world is that no one will accept to bear the weight of kingship. Kingship will remain with none willing to bear alone its weight. That day will be the day whereon wisdom will be manifested among mankind.

The coming of age of the human race has been associated by Shoghi Effendi with the unification of the whole of mankind, the establishment of a world commonwealth, and an unprecedented stimulus to "the intellectual, the moral and spiritual life of the entire human race".
