Bahá’í Sacred Writings, Bahá’u’lláh, #255

It behoveth the loved ones of God to occupy themselves under all circumstances with that which is conducive to the edification of human souls, the advancement of the world of being, and the exaltation of the Word of God, the realization of which dependeth upon the deliberations of the trustees of the House of Justice. Well is it with them that strive to render service to the world of humanity. The influence of these souls will lead the world from hardship to comfort, from poverty to wealth, and from abasement to glory. We beseech God to graciously aid them to observe piety and righteousness, and to open before their faces the portals of grace and mercy, of blessings and wealth. Potent is He to do what He pleaseth, and in His grasp are held the reins of all created things. He doeth and He ordaineth. He is the Supreme Ruler, the Ancient of Days, the Ordainer, the Omniscient.
