“So tremendous is the outpouring of Divine grace in this Dispensation that if mortal hands could be swift enough to record them, within the space of a single day and night there would stream verses of such number as to be equivalent to the whole of the Persian Bayán.”

 

"Stressing the superlative character of His Revelation as compared with the Dispensation preceding it, Bahá’u’lláh makes the following affirmation: “If all the peoples of the world be invested with the powers and attributes destined for the Letters of the Living, the Báb’s chosen disciples, whose station is ten thousand times more glorious than any which the apostles of old have attained, and if they, one and all, should, swift as the twinkling of an eye, hesitate to recognize the light of My Revelation, their faith shall be of no avail and they shall be accounted among the infidels.” “So tremendous is the outpouring of Divine grace in this Dispensation that if mortal hands could be swift enough to record them, within the space of a single day and night there would stream verses of such number as to be equivalent to the whole of the Persian Bayán.”
