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.
- Shoghi Effendi (‘Citadel of Faith’)
