To every discerning and illumined heart it is evident that God, the unknowable Essence, the divine Being, is immensely exalted beyond every human attribute, such as corporeal existence, ascent and descent, egress and regress. Far be it from His glory that human tongue should adequately recount His praise, or that human heart comprehend His fathomless mystery. He is and hath ever been veiled in the ancient eternity of His Essence, and will remain in His Reality everlastingly hidden from the sight of men....[30]
What humanity experiences in turning to the Creator of all existence are the attributes or qualities which are associated with God’s recurring Revelations:
The door of the knowledge of the Ancient of Days being thus closed in the face of all beings, the Source of infinite grace, ... hath caused those luminous Gems of Holiness to appear out of the realm of the spirit, in the noble form of the human temple, and be made manifest unto all men, that they may impart unto the world the mysteries of the unchangeable Being, and tell of the subtleties of His imperishable Essence....[31]
These sanctified Mirrors ... are one and all the Exponents on earth of Him Who is the central Orb of the universe, its Essence and ultimate Purpose. From Him proceed their knowledge and power; from Him is derived their sovereignty. The beauty of their countenance is but a reflection of His image, and their revelation a sign of His deathless glory....[32]
The Revelations of God do not differ in any essential respect from one another, although the changing needs they serve from age to age have called out unique responses from each of them:
These attributes of God are not and have never been vouchsafed specially unto certain Prophets, and withheld from others. Nay, all the Prophets of God, His well-favored, His holy, and chosen Messengers, are, without exception, the bearers of His names, and the embodiments of His attributes. They only differ in the intensity of their revelation, and the comparative potency of their light....[33]
Students of religion are cautioned not to permit theological dogmas or other preconceptions to lead them into discriminating among those whom God has used as channels of His light:
Beware, O believers in the Unity of God, lest ye be tempted to make any distinction between any of the Manifestations of His Cause, or to discriminate against the signs that have accompanied and proclaimed their Revelation. This indeed is the true meaning of Divine Unity, if ye be of them that apprehend and believe this truth. Be ye assured, moreover, that the works and acts of each and every one of these Manifestations of God, nay whatever pertaineth unto them, and whatsoever they may manifest in the future, are all ordained by God, and are a reflection of His Will and Purpose....[34]
Bahá’u’lláh compares the interventions of the Divine Revelations to the return of spring. The Messengers of God are not merely teachers, although this is one of their primary functions. Rather, the spirit of their words, together with the example of their lives, has the capacity to tap the roots of human motivation and to induce fundamental and lasting change. Their influence opens new realms of understanding and achievement:
And since there can be no tie of direct intercourse to bind the one true God with His creation, and no resemblance whatever can exist between the transient and the Eternal, the contingent and the Absolute, He hath ordained that in every age and dispensation a pure and stainless Soul be made manifest in the kingdoms of earth and heaven.... Led by the light of unfailing guidance, and invested with supreme sovereignty, They [the Messengers of God] are commissioned to use the inspiration of Their words, the effusions of Their infallible grace and the sanctifying breeze of Their Revelation for the cleansing of every longing heart and receptive spirit from the dross and dust of earthly cares and limitations. Then, and only then, will the Trust of God, latent in the reality of man, emerge ... and implant the ensign of its revealed glory upon the summits of men’s hearts.[35]
