St. John the Divine had himself, with reference to these two successive Revelations, clearly prophesied: “The second woe is past; and, behold the third woe cometh quickly.” “This third woe,” ‘Abdu’l-Bahá, commenting upon this verse, has explained, “is the day of the Manifestation of Bahá’u’lláh, the Day of God, and it is near to the day of the appearance of the Báb.” “All the peoples of the world,” He moreover has asserted, “are awaiting two Manifestations, Who must be contemporaneous; all wait for the fulfillment of this promise.” And again: “The essential fact is that all are promised two Manifestations, Who will come one following on the other.”
