When Bahá'u'lláh proclaimed His Message to the world in the nineteenth century He made it abundantly clear that the first step essential for the peace and progress of mankind was its unification. As He says, "The well-being of mankind, its peace and security are unattainable unless and until its unity is firmly established." ("The World Order of Bahá'u'lláh", p. 203) To this day, however, you will find most people take the opposite point of view: they look upon unity as an ultimate, almost unattainable goal and concentrate first on remedying all the other ills of mankind.

The second process, the task of breathing life into this unified body—of creating true unity and spirituality culminating in the Most Great Peace—is that of the Bahá'ís, who are labouring consciously, with detailed instructions and continuing Divine guidance, to erect the fabric of the Kingdom of God on earth, into which they call their fellow men, thus conferring upon them eternal life.
