Whatever our shortcomings may be, and however formidable the forces of darkness
which besiege us today, the unification of mankind as outlined and ensured by
the World Order of Bahá’u’lláh will in the fullness of time be firmly and
permanently established. This is Bahá’u’lláh’s promise, and no power on
earth can in the long run prevent or even retard its adequate realization. The
friends should, therefore, not lose hope, but fully conscious of their power
and their rôle they should persevere in their mighty efforts for the
extension and the consolidation of Bahá’u’lláh’s universal dominion on earth.
