And let them rejoice at having learned through consistent, systematic action how to establish a rhythm of growth that pays due attention to the essential elements of expansion, consolidation, reflection and planning.

Universal House of Justice, 20 October 2008, to the Bahá’ís of the World

Sustaining growth in cluster after cluster will depend on the qualities that distinguish your service to the peoples of the world.  So free must be your thoughts and actions of any trace of prejudice—racial, religious, economic, national, tribal, class, or cultural—that even the stranger sees in you loving friends.  So high must be your standard of excellence and so pure and chaste your lives that the moral influence you exert penetrates the consciousness of the wider community.  Only if you demonstrate the rectitude of conduct to which the writings of the Faith call every soul will you be able to struggle against the myriad forms of corruption, overt and subtle, eating at the vitals of society.  Only if you perceive honour and nobility in every human being—this independent of wealth or poverty—will you be able to champion the cause of justice.  And to the extent that administrative processes of your institutions are governed by the principles of Bahá’í consultation will the great masses of humanity be able to take refuge in the Bahá’í community.

The "building process," to which they are consecrated, is "the one hope of a stricken society."  For, it is "actuated by the generating influence of God's changeless Purpose, and is evolving within the framework of the Administrative Order of His Faith."

They alone are aware of the silent growth of that orderly world polity whose fabric they themselves are weaving.

The Bahá’í teachings foster the use of the rational faculties in a spirit of inquiry, to unravel the mysteries of spiritual and material worlds, and to thus contribute to the growth of religious and scientific understanding. Hence, we may confidently anticipate that the mysteries of the organic growth will become progressively disclosed, as our understanding of the interplay between the spiritual and the material determinants of growth increase, and the passage of time reveals more fully the course followed by the Bahá’í Community in it’s expansion.
