“Although your realities are shaped by a broad diversity of circumstances, yet a desire to bring about constructive change and a capacity for meaningful service, both characteristic of your stage of life, are neither limited to any race or nationality, nor dependent upon material means. This bright period of youth you share is experienced by all—but it is brief, and buffeted by numerous social forces. How important it is, then, to strive to be among those who, in the words of ‘Abdu’l-Bahá, ‘plucked the fruit of life’.”

Youth have played a vital role in Bahá’í history. The Báb Himself declared His mission when He was but twenty-five years old and so many among the band of His followers were in the prime of their youth when they embraced His Revelation. During the ministries of Bahá’u’lláh and ‘Abdu’l-Bahá, young people were at the forefront of efforts to proclaim the message of the new Faith and to share its teachings with others.
