The Guardian believes that a great deal of the difficulties from which the believers ... feel themselves to be suffering are caused by their neither correctly understanding nor putting into practice the administration. They seem - many of them - to be prone to continually challenging and criticizing the decisions of their Assemblies. If the Bahá'ís undermine the very bodies which are, however immaturely, seeking to co-ordinate Bahá'í activities and administer Bahá'í affairs, if they continually criticize their acts and challenge or belittle their decisions, they not only prevent any real rapid progress in the Faith's development from taking place, but they repel outsiders who quite rightly may ask how we ever expect to unite the whole world when we are so disunited among ourselves!
There is only one remedy for this: to study the administration, to obey the Assemblies, and each believer seek to perfect his own character as a Bahá'í. We can never exert the influence over others which we can exert over ourselves. If we are better, if we show love, patience, and understanding of the weaknesses of others; if we seek to never criticize but rather encourage, others will do likewise, and we can really help the Cause through our example and spiritual strength. The Bahá'ís everywhere, when the administration is first established, find it very difficult to adjust themselves. They have to learn to obey, even when the Assembly may be wrong, for the sake of unity. They have to sacrifice their personalities, to a certain extent, in order that the community life may grow and develop as a whole. These things are difficult - but we must realize that they will lead us to a very much greater, more perfect, way of life when the Faith is properly established according to the administration.
