The Báb in His Writings made certain that His Covenant concerning Bahá’u’lláh is plainly and clearly asserted for all. In just the single compilation of His works translated authoritatively into English, “Selections from the Writings of the Báb”, the reader finds no fewer than 76 occurrences of the phrase “Whom God shall make manifest”; how many more such mentions must have permeated the Báb’s overall Revelation! Other forms of the phrase also appear in the compilation, most notably the very first Tablet in the book, which begins:
“A TABLET ADDRESSED TO ‘HIM WHO WILL BE MADE MANIFEST’
“This is an epistle from this lowly servant to the All-Glorious Lord — He Who hath been aforetime and will be hereafter made manifest. Verily He is the Most Manifest, the Almighty. In the name of the Sovereign Lord, the Lord of Power.”
It is followed by this Tablet of the Báb, quoted in full here.
“A SECOND TABLET ADDRESSED TO ‘HIM WHO WILL BE MADE MANIFEST’
“May the glances of Him Whom God shall make manifest illumine this letter at the primary school.
HE IS THE MOST GLORIOUS.
HE is God, no God is there but Him, the Almighty, the Best-Beloved. All that are in the heavens and on the earth and whatever lieth between them are His. Verily He is the Help in Peril, the Self-Subsisting.
“This is a letter from God, the Help in Peril, the Self-Subsisting, unto God, the Almighty, the Best-Beloved, to affirm that the Bayán and such as bear allegiance to it are but a present from me unto Thee and to express my undoubting faith that there is no God but Thee, that the kingdoms of Creation and Revelation are Thine, that no one can attain anything save by Thy power and that He Whom Thou hast raised up is but Thy servant and Thy Testimony. I, indeed, beg to address Him Whom God shall make manifest, by Thy leave in these words: ‘Shouldst Thou dismiss the entire company of the followers of the Bayán in the Day of the Latter Resurrection by a mere sign of Thy finger even while still a suckling babe, Thou wouldst indeed be praised in Thy indication. And though no doubt is there about it, do Thou grant a respite of nineteen years as a token of Thy favor so that those who have embraced this Cause may be graciously rewarded by Thee. Thou art verily the Lord of grace abounding. Thou dost indeed suffice every created thing and causest it to be independent of all things, while nothing in the heavens or on the earth or that which lieth between them can ever suffice Thee.’ Verily Thou art the Self-Sufficient, the All-Knowing; Thou art indeed potent over all things.”
These two Tablets of the Báb are replete with measures with which the truth of Bahá’u’lláh’s Revelation can be affirmed. In the Kitáb-i-Aqdas, Bahá’u’lláh refers back clearly to this second Tablet’s mention of the “primary school”, bestowing its full, true meaning for the reader:
“O Pen of the Most High! Move Thou upon the Tablet at the bidding of Thy Lord, the Creator of the Heavens, and tell of the time when He Who is the Dayspring of Divine Unity purposed to direct His steps towards the School of Transcendent Oneness; haply the pure in heart may gain thereby a glimpse, be it as small as a needle’s eye, of the mysteries of Thy Lord, the Almighty, the Omniscient, that lie concealed behind the veils. Say: We, indeed, set foot within the School of inner meaning and explanation when all created things were unaware. We saw the words sent down by Him Who is the All-Merciful, and We accepted the verses of God, the Help in Peril, the Self-Subsisting, which He [the Báb] presented unto Us, and hearkened unto that which He had solemnly affirmed in the Tablet. This We assuredly did behold. And We assented to His wish through Our behest, for truly We are potent to command.”
Thus the Twin Manifestations bind their Dispensations together inseparably. Often we readers find challenging the ways in which the Manifestations of God refer to one another and to God, so that when the Báb writes “This is a letter from God, the Help in Peril, the Self-Subsisting, unto God, the Almighty, the Best-Beloved…”, and Bahá’u’lláh writes in response over the arch of time and place “We accepted the verses of God, the Help in Peril, the Self-Subsisting, which He [the Báb] presented unto Us”, we are pressed to realize that our distinctions of station and revelation all fail to embrace the incomparably-rich and unifying truths of the divine realms beyond our human comprehension.
Many passages from the Writings of the Báb and Bahá’u’lláh reinforce and demonstrate the deep, unbreakable bond that characterizes and energizes this glorious Dispensation of Bahá’u’lláh. Perhaps one of the simplest and clearest statements comes to us from ‘Abdu’l-Bahá:
“… Bahá’u’lláh declared the Báb’s mission to be true and promulgated His teachings. The Báb announced that the greater Manifestation would take place after Him and called the Promised One ‘Him Whom God shall make manifest,’ saying that nine years later the reality of His own mission would become apparent. In His writings He stated that in the ninth year this expected One would be known; in the ninth year they would attain to all glory and felicity; in the ninth year they would advance rapidly. Between Bahá’u’lláh and the Báb there was communication privately. The Báb wrote a letter containing three hundred and sixty derivatives of the root Baha. The Báb was martyred in Tabriz; and Bahá’u’lláh, exiled into Iraq in 1852, announced Himself in Baghdad. For the Persian government had decided that as long as He remained in Persia the peace of the country would be disturbed; therefore, He was exiled in the expectation that Persia would become quiet. His banishment, however, produced the opposite effect. New tumult arose, and the mention of His greatness and influence spread everywhere throughout the country. The proclamation of His manifestation and mission was made in Baghdad. He called His friends together there and spoke to them of God.”
A simple pattern emerges. From 1844 to 1853 – nine years passed from the Declaration of the Báb to the Revelation of Bahá’u’lláh as He experienced it in the Síyáh-Chál (from the Báb, as cited by ‘Abdu’l-Bahá: “He stated that in the ninth year this expected One would be known”). From 1844 to 1863 – nineteen years passed from the Declaration of the Báb to the Revelation of Bahá’u’lláh as He announced it in the Garden of Ridvan: “a respite of nineteen years” (from the Báb). No reinterpretation of years is necessary here. The Twin Manifestations of God stand together at the entrance to a world made new, as ‘Abdu’l-Bahá tells us:
“This is a new cycle of human power. All the horizons of the world are luminous, and the world will become indeed as a garden and a paradise. It is the hour of unity of the sons of men and of the drawing together of all races and all classes. You are loosed from ancient superstitions which have kept men ignorant, destroying the foundation of true humanity.
“The gift of God to this enlightened age is the knowledge of the oneness of mankind and of the fundamental oneness of religion. War shall cease between nations, and by the will of God the Most Great Peace shall come; the world will be seen as a new world, and all men will live as brothers.”
