…in this cycle of Bahá'u'lláh verbal confessions and
acknowledgements, literal faith and certainty and external relations are of no
avail. Nay, rather, the beloved of God and the maid-servants of the Merciful
must manifest such attributes and ethical conduct as to embody and personify
the teachings of Bahá'u'lláh. They must promulgate the law of the Kingdom with
deeds and not words. Thus may they become the quintessence of being, the signs
of the Kingdom of God, standards of the Supreme Concourse.

of the West, vol. 1, no. 4, May 17, 1910)
