Be not concerned with the smallness of your numbers, neither
be oppressed by the multitude of an unbelieving world... Exert yourselves; your
mission is unspeakably glorious. Should success crown your enterprise, America
will assuredly evolve into a center from which waves of spiritual power will
emanate, and the throne of the Kingdom of God will, in the plenitude of its
majesty and glory, be firmly established....
(‘Abdu’l-Baha, quoted by Shoghi
Effendi in a letter dated June 15, 1946; ‘Messages to America’)
