I feel thoroughly convinced, and am moved to share this firm conviction within me with that great company of western believers, that in the speedy resumption of the sorely-neglected construction of the Mashriqu’l-Adhkar at Wilmette lies our undoubted privilege, our primary obligation, our most vital opportunity to lend an unprecedented impetus to the advancement of the Cause, not only throughout the West but in every country of the world. I would not stress at this moment the prestige and good name of the Cause, much as they are involved in this most pressing issue, I would not dwell upon the eager expectancy with which the unnumbered followers of the Faith as well as the vast number of the non-believers in almost every section of society throughout the East are awaiting to behold that noble structure rear its head in the heart of that far-western continent; nor would I expatiate on the ineffable beauty of this holy Edifice, its towering glory, its artistic design, its unique character, or its functions in the organic life of the Bahá’í community of the future. But I would with all the strength of my conviction emphasize the immeasurable spiritual significance of an Edifice, so beauteous, so holy, erected solely by the concerted efforts, strained to the utmost degree of self-sacrifice, of the entire body of the believers who are fully conscious of the significance of the Revelation of Bahá’u’lláh. In this vast endeavor, unparalleled in modern times, its world-wide range, its spontaneity, its heroic and holy character, the American believers, on the soil of whose country Bahá’u’lláh’s first universal House of Worship is to be built, must, if they be faithful to their trust, claim and fulfill a pre-eminent share in the collective contributions offered by the Bahá’ís of the world.
