The soul that hath remained faithful to the Cause of God, and stood unwaveringly firm in His Path shall, after his ascension, be possessed of such power that all the worlds which the Almighty hath created can benefit through him. Such a soul provideth, at the bidding of the Ideal King and Divine Educator, the pure leaven that leaveneth the world of being, and furnisheth the power through which the arts and wonders of the world are made manifest. (Baha’u’llah, 'Gleanings from the Writings of Bahá'u'lláh’; The Compilation of Compilations, vol. III, The Importance of Arts in Promoting the Faith)
