"No God is there but Thee, the Strong, the Unconstrained.”

"“O God, my God! Thou hast lighted the lamp of Thy Cause with the oil of wisdom; protect it from contrary winds. The lamp is Thine, and the glass is Thine, and all things in the heavens and on earth are in the grasp of Thy power. Bestow justice upon the rulers, and fairness upon the divines. Thou art the All-Powerful, Who, through the motion of Thy Pen, hast aided Thine irresistible Cause, and guided aright Thy loved ones. Thou art the Possessor of power, and the King of might. No God is there but Thee, the Strong, the Unconstrained.”

-Bahá'u'lláh, Epistle to the Son of the Wolf, pp. 104-105
