No power on earth can prevail against the armies of justice,
and every citadel must fall before them; for men willingly go down under the
triumphant strokes of this decisive blade, and desolate places bloom and
flourish under the tramplings of this host. There are two mighty banners which,
when they cast their shadow across the crown of any king, will cause the
influence of his government quickly and easily to penetrate the whole earth,
even as if it were the light of the sun: the first of these two banners is
wisdom; the second is justice. Against these two most potent forces, the iron
hills cannot prevail, and Alexander’s wall will break before them.
(‘Abdu’l-Baha,
‘The Secret of Divine Civilization’)
