In the course of their endeavours, the believers encounter receptivity within distinct populations who represent a particular ethnic, tribal, or other group and who may be concentrated in a small setting or present throughout the cluster and well beyond it. There is much to be learned about the dynamics involved when a population of this kind embraces the Faith and is galvanized through its edifying influence. We stress the importance of this work for advancing the Cause of God: every people has a share in the World Order of Bahá’u’lláh, and all must be gathered together under the banner of the oneness of humanity. In its early stages, the systematic effort to reach out to a population and foster its participation in the process of capacity building accelerates markedly when members of that population are themselves in the vanguard of such an effort. These individuals will have special insight into those forces and structures in their societies that can, in various ways, reinforce the endeavours under way.
