We must build up our Baha'i system, and leave the faulty systems of the world to go their own way.

Because love for our fellowmen and anguish at their plight are essential parts of a true Bahá'í's life, we are continually drawn to do what we can to help them. It is vitally important that we do so whenever the occasion presents itself, for our actions must say the same thing as our words -- but this compassion for our fellows must not be allowed to divert our energies into channels which are ultimately doomed to failure, causing us to neglect the most important and fundamental work of all. There are hundreds of thousands of well-wishers of mankind who devote their lives to works of relief and charity, but a pitiful few to do the work which God Himself most wants done: the spiritual awakening and regeneration of mankind.

(The Universal House of Justice, Messages 1963 to 1986, p. 127)

"We must build up our Bahá'í system, and leave the faulty systems of the world to go their own way. We cannot change them through becoming involved in them; on the contrary they will destroy us."

(Bahá'í News, No. 215, p.1) (The Universal House of Justice, Wellspring of Guidance, pg 134-135)
