The “Spirit of Faith and Peace as revealed in the Cause of Bahá'u'lláh” "will" eventually “fill the world and the darkness of strife” will “be no more”

Having returned to the Holy Land with a renewed vigour and a refreshed spirit, I shall not fail with the help of the Master to do my part in enabling you to carry on further and still further the Glorious Standard of Baha to the very heart and uttermost confines of Germany and thus hasten the Day when the Spirit of Faith and Peace as revealed in the Cause of Bahá'u'lláh will fill the world and the darkness of strife be no more. (Shoghi Effendi, excerpt from a letter dated 17 December 1922 to the Baha’is of Germany; The Light of Divine Guidance v I, p. 8) (To see the entire letter please visit Messages to the Baha’i World)
