The appearance of two contemporaneous Manifestations of God and the resulting effect

All the peoples of the world are awaiting two Manifestations, Who must be contemporaneous. This is what they all have been promised. In the Torah, the Jews are promised the Lord of Hosts and the Messiah. In the Gospel, the return of Christ and Elijah is foretold. In the religion of Muhammad, there is the promise of the Mahdi and the Messiah. The same holds true of the Zoroastrians and others, but to belabour this matter would prolong our discourse. Our meaning is that all have been promised the advent of two successive Manifestations. It has been prophesied that, through these twin Manifestations, the earth will become another earth; all existence will be renewed; the contingent world will be clothed with the robe of a new life; justice and righteousness will encompass the globe; hatred and enmity will disappear; whatever is the cause of division among peoples, races, and nations will be obliterated; and that which ensures unity, harmony, and concord will be promoted. The heedless will arise from their slumber; the blind will see; the deaf will hear; the dumb will speak; the sick will be healed; the dead will be quickened; and war will give way to peace. Enmity will be transmuted into love; the root causes of contention and strife will be eliminated; mankind will attain true felicity; this world will mirror forth the heavenly Kingdom; and the earth below will become the throne of the realm above. All nations will become one nation; all religions will become one religion; all mankind will become one family and one kindred; all the regions of the earth will become as one; racial, national, personal, linguistic, and political prejudices will be effaced and extinguished; and all will attain everlasting life under the shadow of the Lord of Hosts.
