Gird up the loins of thine endeavor, that haply thou mayest guide thy neighbor to the law of God, the Most Merciful. Such an act, verily, excelleth all other acts in the sight of God, the All-Possessing, the Most High. Such must be thy steadfastness in the Cause of God, that no earthly thing whatsoever will have the power to deter thee from thy duty. Though the powers of earth be leagued against thee, though all men dispute with thee, thou must remain unshaken.
