The well-being of mankind, its peace and security, are unattainable unless
and until its unity is firmly established. This unity can never be
achieved so long as the counsels which the Pen of the Most High hath
revealed are suffered to pass unheeded.

We pray God--exalted be His glory--and cherish the hope that He may
graciously assist the manifestations of affluence and power and the
daysprings of sovereignty and glory, the kings of the earth--may God aid
them through His strengthening grace--to establish the Lesser Peace. This,
indeed, is the greatest means for ensuring the tranquillity of the
nations. It is incumbent upon the Sovereigns of the world--may God assist
them--unitedly to hold fast unto this Peace, which is the chief instrument
for the protection of all mankind. It is Our hope that they will arise to
achieve what will be conducive to the well-being of man. It is their duty
to convene an all-inclusive assembly, which either they themselves or
their ministers will attend, and to enforce whatever measures are required
to establish unity and concord amongst men. They must put away the weapons
of war, and turn to the instruments of universal reconstruction. Should
one king rise up against another, all the other kings must arise to deter
him. Arms and armaments will, then, be no more needed beyond that which is
necessary to ensure the internal security of their respective countries.
If they attain unto this all-surpassing blessing, the people of each
nation will pursue, with tranquillity and contentment, their own
occupations, and the groanings and lamentations of most men would be
silenced. We beseech God to aid them to do His will and pleasure. He,
verily, is the Lord of the throne on high and of earth below, and the Lord
of this world and of the world to come. It would be preferable and more
fitting that the highly-honoured kings themselves should attend such an
assembly, and proclaim their edicts. Any king who will arise and carry out
this task, he, verily will, in the sight of God, become the cynosure of
all kings. Happy is he, and great is his blessedness!
