Only those who are willing to associate the Revelation proclaimed by Bahá'u'lláh with the consummation of so stupendous an evolution in the collective life of the whole human race can grasp the significance of the words which He, while alluding to the glories of this promised Day and to the duration of the Bahá'í Era, has deemed fit to utter. "This is the King of Days," He exclaims, "the Day that hath seen the coming of the Best-Beloved, Him Who, through all eternity, hath been acclaimed the Desire of the World." "The Scriptures of past Dispensations," He further asserts, "celebrate the great jubilee that must needs greet this most great Day of God. Well is it with him that hath lived to see this Day and hath recognized its station." "It is evident," He, in another passage explains, "that every age in which a Manifestation of God hath lived is divinely-ordained, and may, in a sense, be characterized as God's appointed Day. This Day, however, is unique, and is to be distinguished from those that have preceded it. The designation `Seal of the Prophets' fully revealeth its high station. The Prophetic Cycle hath verily ended. The Eternal Truth is now come. He hath lifted up the ensign of power, and is now shedding upon the world the unclouded splendor of His Revelation." "In this most mighty Revelation," He, in categorical language, declares, "all the Dispensations of the past have attained their highest, their final consummation. That which hath been made manifest in this préeminent, this most exalted Revelation, standeth unparalleled in the annals of the past, nor will future ages witness its like."

`Abdu'l-Bahá's authentic pronouncements should, likewise, be recalled as confirming, in no less emphatic manner, the unexampled vastness of the Bahá'í Dispensation. "Centuries," He affirms in one of His Tablets, "nay, countless ages, must pass away ere the Day-Star of Truth shineth again in its mid-summer splendor, or appeareth once more in the radiance of its vernal glory... The mere contemplation of the Dispensation inaugurated by the Blessed Beauty would have sufficed to overwhelm the saints of bygone ages --saints who longed to partake, for one moment, of its great glory." "Concerning the Manifestations that will come down in the future `in the shadows of the clouds,'" He, in a still more definite language, affirms, "know, verily, that in so far as their relation to the Source of their inspiration is concerned, they are under the shadow of the Ancient Beauty. In their relation, however, to the age in which they appear, each and every one of them `doeth whatsoever He willeth.'" "This holy Dispensation," He, alluding to the Revelation of Bahá'u'lláh, explains, "is illumined with the light of the Sun of Truth shining from its most exalted station, and in the plenitude of its resplendency, its heat and glory."
