As to the
order and the management of the spiritual affairs of the friends, that which is
very important now is the consolidation of the Spiritual Assemblies in every
centre, because on these fortified and unshakeable foundations, God's Supreme
House of Justice shall be erected and firmly established in the days to come.
When this most great Edifice shall be reared on such an immovable foundation,
God’s purpose, wisdom, universal truths, mysteries and realities of the
Kingdom, which the mystic revelation of Bahá'u'lláh has deposited within the
Will and Testament of 'Abdu'l-Bahá, shall gradually be revealed and made
manifest.
- Shoghi Effendi (From a letter dated 19 December 1923 -- translated
from the Persian; included in a letter from the Universal House of Justice dated 9
March 1965)
