Shoghi writing in 1929:
The hour for such a world-wide and concentrated appeal is not yet 164 come, but it behooves us, while expectantly watching from a distance the moving spectacle of the struggling Faith of Bahá’u’lláh, to seek abiding solace and strength from the reflection that whatever befalls this Cause, however grievous and humiliating the visitations that from time to time may seem to afflict the organic life or interfere with the functions of the administrative machinery of the Bahá’í Faith, such calamities cannot but each eventually prove to be a blessing in disguise designed, by a Wisdom inscrutable to us all, to establish and consolidate the sovereignty of Bahá’u’lláh on this earth.

then on the next page talking about Shi'a clerical persecution in 'Iraq:
Surely, if we read the history of this case aright, we cannot but discern the direction which the forces, released by these prophetic utterances of Bahá’u’lláh sixty years ago, are destined to take in the eventual solution of this mighty issue:—
“In truth I declare, it shall be so abased in the days to come as to cause tears to flow from every discerning eye…. And in the fullness of time shall the Lord, by the power of truth, exalt it in the eyes of all the world, cause it to become the mighty standard of His Dominion, the Shrine round which shall circle the concourse of the faithful.”
