The experience of the Bahá'í community may be seen as an example of this enlarging unity. It is a community of some three to four million people drawn from many nations, cultures, classes and creeds, engaged in a wide range of activities serving the spiritual, social and economic needs of the peoples of many lands. It is a single social organism, representative of the diversity of the human family, conducting its affairs through a system of commonly accepted consultative principles, and cherishing equally all the great outpourings of divine guidance in human history. Its existence is yet another convincing proof of the practicality of its Founder's vision of a united world, another evidence that humanity can live as one global society, equal to whatever challenges its coming of age may entail. If the Bahá'í experience can contribute in whatever measure to reinforcing hope in the unity of the human race, we are happy to offer it as a model for study.
