God’s purpose in sending His Prophets unto men is twofold. The first is to liberate the children of men from the darkness of ignorance, and guide them to the light of true understanding. The second is to ensure the peace and tranquillity of mankind, and provide all the means by which they can be established. (“Gleanings from the Writings of Bahá’u’lláh”, pp. 79–80) [2] 3: O ye that dwell on earth! The distinguishing feature that marketh the... O ye that dwell on earth! The distinguishing feature that marketh the preeminent character of this Supreme Revelation consisteth in that We have ... laid down the essential prerequisites of concord, of understanding, of complete and enduring unity. Well is it with them that keep My statutes. (“Gleanings from the Writings of Bahá’u’lláh”, p. 97) [3] 4: The Great Being, wishing to reveal the prerequisites of the peace and... The Great Being, wishing to reveal the prerequisites of the peace and tranquillity of the world and the advancement of its peoples, hath written: The time must come when the imperative necessity for the holding of a vast, an all-embracing assemblage of men will be universally realized. The rulers and kings of the earth must needs attend it, and, participating in its deliberations, must consider such ways and means as will lay the foundations of the world’s Great Peace amongst men. Such a peace demandeth that the Great Powers should resolve, for the sake of the tranquillity of the peoples of the earth, to be fully reconciled among themselves. Should any king take up arms against another, all should unitedly arise and prevent him. If this be done, the nations of the world will no longer require any armaments, except for the purpose of preserving the security of their realms and of maintaining internal order within their territories. This will ensure the peace and composure of every people, government and nation. We fain would hope that the kings and rulers of the earth, the mirrors of the gracious and almighty name of God, may attain unto this station, and shield mankind from the onslaught of tyranny. ...The day is approaching when all the peoples of the world will have adopted one universal language and one common script. When this is achieved, to whatsoever city a man may journey, it shall be as if he were entering his own home. These things are obligatory and absolutely essential. It is incumbent upon every man of insight and understanding to strive to translate that which hath been written into reality and action.... That one indeed is a man who, today, dedicateth himself to the service of the entire human race. The Great Being saith: Blessed and happy is he that ariseth to promote the best interests of the peoples and kindreds of the earth. In another passage He hath proclaimed: It is not for him to pride himself who loveth his own country, but rather for him who loveth the whole world. The earth is but one country, and mankind its citizens.
