The purpose of teaching the Faith

Teaching the Faith embraces many diverse activities, all of which are vital to success, and each of which reinforces the other. Time and again the beloved Guardian emphasized that expansion and consolidation are twin and inseparable aspects of teaching that must proceed simultaneously, yet one still hears believers discussing the virtues of one as against the other. The purpose of teaching is not complete when a person declares that he has accepted Baha'u'llah as the Manifestation of God for this age; the purpose of teaching is to attract human beings to the divine Message and so imbue them with its spirit that they will dedicate themselves to its service, and this world will become another world and its people another people. Viewed in this light a declaration of faith is merely a milestone along the way -- albeit a very important one. Teaching may also be likened to kindling a fire, the fire of faith, in the hearts of men. If a fire burns only so long as the match is held to it, it cannot truly be said to have been kindled; to be kindled it must continue to burn of its own accord. Thereafter more fuel can be added and the flame can be fanned, but even if left alone for a period, a truly kindled fire will not be extinguished by the first breath of wind.

The aim, therefore, of all Baha'i institutions and Baha'i teachers is to advance continually to new areas and strata of society, with such thoroughness that, as the spark of faith kindles the hearts of the hearers, the teaching of the believers continues until, and even after, they shoulder their responsibilities as Baha'is and participate in both the teaching and administrative work of the Faith.
