In one of the earliest Tablets addressed by Him [‘Abdu’l-Baha] to the American believers these equally significant words have been penned: “If ye be truly united, if ye agree to promote that which is the essential purpose, and to show forth an all-unifying love, I swear by Him Who causeth the seed to split and the breeze to waft, so great a light will shine forth from your faces as to reach the highest heavens, the fame of your glory will be noised abroad, the evidences of your preeminence will spread throughout all regions, your power will penetrate the realities of all things, your aims and purposes will exert their influence upon the great and mighty nations, your spirits will encompass the whole world of being, and ye will discover yourselves to be kings in the dominions of the Kingdom, and attired with the glorious crowns of the invisible Realm, and become the marshals of the army of peace, and princes of the forces of light, and stars shining from the horizon of perfection, and brilliant lamps shedding their radiance upon men.” 
(Shoghi Effendi, from a letter dated June 5, 1947; ‘Citadel of Faith’)
