Not by the force of numbers, not by the mere exposition of a set of new and noble principles, not by an organised campaign of teaching—no matter how worldwide and elaborate in its character—not even by the staunchness of our faith or the exaltation of our enthusiasm, can we ultimately hope to vindicate in the eyes of a critical and sceptical age the supreme claim of the Abhá Revelation. One thing and only one thing will unfailingly and alone secure the undoubted triumph of this sacred Cause, namely, the extent to which our own inner life and private character mirror forth in their manifold aspects the splendour of those eternal principles proclaimed by Bahá’u’lláh.
