For a global society to flourish, Bahá'u'lláh said, it must be based on certain fundamental principles. They include: the elimination of all forms of prejudice; full equality between the sexes; recognition of the essential oneness of the world's great religions; the elimination of extremes of poverty and wealth; universal education; the harmony of science and religion; a sustainable balance between nature and technology; and the establishment of a world federal system, based on collective security and the oneness of humanity.
The essential message of Bahá'u'lláh is that of unity. He taught that there is only one God, that there is only one human race, and that all the world's religions have been stages in the revelation of God's will and purpose for humanity. In this day, Bahá'u'lláh said, humanity has collectively come of age. As foretold in all of the world's scriptures, the time has arrived for the uniting of all peoples into a peaceful and integrated global society. "The earth is but one country, and mankind its citizens," He wrote.
