Nor, indeed, can these self-denying acts, by both the rich and the poor, be productive of the fullest possible benefit unless this sacrificial effort is neither momentary nor haphazard, but rather systematic and continuous throughout the period of the present emergency. Then and only then will this holy edifice, symbol and harbinger of a world civilization as yet unborn, and the embodiment of the sacrifice of a multitude of the upholders of the Faith of Bahá’u’lláh, release the full measure of the regenerative power with which it has been endowed, shed in all its plenitude the glory of the Most Holy Spirit dwelling within it, and vindicate, beyond the shadow of a doubt, the truth of every single promise recorded by the pen of ‘Abdu’l-Bahá pertaining to its destiny. No more befitting consummation for this magnificent enterprise can be envisaged than that this noble edifice, whose cornerstone has been laid by ‘Abdu’l-Bahá’s own hands, the preliminary measure for whose construction synchronized with the formal interment of the Báb’s remains on Mt. Carmel, within whose walls the first Centenary of the birth of His ministry has been celebrated, whose interior ornamentation has coincided with the construction of the arcade of His Sepulcher, should be vouchsafed the honor of having the Jubilee of its inception coincide with, and celebrated on the occasion of, the Centenary of the birth of Bahá’u’lláh’s prophetic Mission in the Síyáh-_Ch_ál of Ṭihrán.
