O ye friends of God!
Exert ye with heart and soul, so that association, love, unity and agreement be
obtained between the hearts, all the aims may be merged into one aim, all the
songs become one song and the power of the Holy Spirit may become so
overwhelmingly victorious as to overcome all the forces of the world of nature.
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 plentitude of its majesty and glory, be firmly established.
- ‘Abdu’l-Baha (‘Tablets of the Divine Plan’)
