Indeed, the civilization that beckons humanity will not be attained through the efforts of the Bahá’í community alone. Numerous groups and organizations, animated by the spirit of world solidarity that is an indirect manifestation of Bahá’u’lláh’s conception of the principle of the oneness of humankind, will contribute to the civilization destined to emerge out of the welter and chaos of present-day society. It should be clear to everyone that the capacity created in the Bahá’í community over successive global Plans renders it increasingly able to lend assistance in the manifold and diverse dimensions of civilization building, opening to it new frontiers of learning.
(Universal House of Justice, Ridván Message 2010, paragraphs 25-26)
Not by the force of numbers, not by the mere exposition of a set of new and noble principles, not by an organized 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 Bahá 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 splendor of those eternal principles proclaimed by Bahá’u’lláh.
(Shoghi Effendi, Bahá’í Administration, p. 66)
Not until the dynamic love we cherish for Him is sufficiently reflected in its power and purity in all our dealings with our fellow-men, however remotely connected and humble in origin, can we hope to exalt in the eyes of a self-seeking world the genuineness of the all-conquering love of God. Not until we live ourselves the life of a true Bahá’í can we hope to demonstrate the creative and transforming potency of the Faith we profess. Nothing but the abundance of our actions, nothing but the purity of our lives and the integrity of our characters, can in the last resort establish our claim that the Bahá’í spirit is in this day the sole agency that can translate a long-cherished ideal into an enduring achievement.
