"Three great fields of service lie open before young Bahá'ís, in which they will simultaneously be remaking the character of human society and preparing themselves for the work they can undertake later in their lives.
"First, the foundation of all their other accomplishments, is their study of the teachings, the spiritualization of their lives, and the forming of their characters in accordance with the standards of Bahá'u'lláh. As the moral standards of the people around us collapse and decay, whether of the centuries civilizations of the East, the more recent cultures of Christendom and Islam, or of the rapidly changing tribal societies of the world, the Bahá'ís must increasingly stand out as pillars of righteousness and forbearance. The life of a Bahá'í will be characterized by truthfulness and decency; he will walk uprightly among his fellowmen, dependent upon none save God, yet linked by bonds of love and brotherhood with all mankind; he will be entirely detached from the loose standards, the decadent theories, the frenetic experimentation, the desperation of present-day society, will look upon his neighbors with a bright and friendly face, and be a beacon light and a haven for all those who would emulate his strength of character and assurance of soul.
"The second field of service, which is linked intimately with the first, is teaching the Faith, particularly to their fellow youth, among whom are some of the most open and seeking minds in the world. Not yet having acquired all the responsibilities of a family or a long-established home and job, youth can the more easily choose where they will live and study or work. In the world at large young people travel hither and thither seeking amusement, education, and experiences. Bahá'í youth, bearing the incomparable treasure of the Word of God for this Day, can harness this mobility into service for mankind and can choose their places of residence, their areas of travel, and their types of work with the goal in mind of how they can best serve the Faith.
"The third field of service is the preparation by youth for their later years. It is the obligation of a Bahá'í to educate his children; likewise it is the duty of the children to acquire knowledge of the arts and sciences and to learn a trade or a profession whereby they, in turn, can earn their living and support their families. This, for a Bahá'í youth, is in itself a service to God, a service, moreover, which can be combined with teaching the Faith and often with pioneering. The Bahá'í community will need men and women of many skills and qualifications; for, as it grows in size the sphere of its activities in the life of society will increase and diversify. Let Bahá'í youth, therefore, consider the best ways in which they can ug and develop their native abilities for the service of mankind and the Cause of God, whether this be as farmers, teachers, doctors, artisans, musicians, or any one of the multitude of livelihoods that are open to them."
