…in this marvelous cycle[of Baha’u’llah] the earth will be transformed, and the world of humanity arrayed in tranquillity and beauty. Disputes, quarrels and murders will be replaced by peace, truth and concord; among the nations, peoples, races and countries, love and amity will appear. Cooperation and union will be established, and finally war will be entirely suppressed. When the laws of the Most Holy Book are enforced, contentions and disputes will find a final sentence of absolute justice before a general tribunal of the nations and kingdoms, and the difficulties that appear will be solved. The five continents of the world will form but one, the numerous nations will become one, the surface of the earth will become one land, and mankind will be a single community. The relations between the countries—the mingling, union and friendship of the peoples and communities—will reach to such a degree that the human race will be like one family and kindred. The light of heavenly love will shine, and the darkness of enmity and hatred will be dispelled from the world. Universal peace will raise its tent in the center of the earth, and the blessed Tree of Life will grow and spread to such an extent that it will overshadow the East and the West. Strong and weak, rich and poor, antagonistic sects and hostile nations—which are like the wolf and the lamb, the leopard and kid, the lion and the calf—will act toward each other with the most complete love, friendship, justice and equity. The world will be filled with science, with the knowledge of the reality of the mysteries of beings, and with the knowledge of God.
