" ... they must raise in every land the triumphal cry “O Thou the Glory of Glories!” (Yá Bahá’u’l-Abhá) ..."

" ... It behooveth them not to rest for a moment, neither to seek repose. They must disperse themselves in every land, pass by every clime, and travel throughout all regions. Bestirred, without rest and steadfast to the end they must raise in every land the triumphal cry “O Thou the Glory of Glories!” (Yá Bahá’u’l-Abhá), must achieve renown in the world wherever they go, must burn brightly even as a candle in every meeting and must kindle the flame of Divine love in every assembly; that the light of truth may rise resplendent in the midmost heart of the world, that throughout the East and throughout the West a vast concourse may gather under the shadow of the Word of God, that the sweet savors of holiness may be diffused, that faces may shine radiantly, hearts be filled with the Divine spirit and souls be made heavenly."
