Shoghi Effendi’s soul-stirring letter, The Advent of Divine Justice, was written in 1938 during a time of tremendous turmoil in world affairs. As we find ourselves once again in the midst of breathtaking worldwide change, we turn to his brilliant analysis of our strengths and weaknesses, to his unerring guidance, and to his assurances of our “unspeakably glorious destiny.” While addressed “To the beloved of God” in the United States and Canada—countries not yet caught up in the vortex of World War II—his sweeping vision of the World Order of Bahá’u’lláh is thrilling for all Bahá’ís for all time. Shoghi Effendi helps us understand that there is one Divine Plan, “whose Source is God, whose author is Bahá’u’lláh,” and “whose outline has been delineated for them by the pen of ‘Abdu’l-Bahá.”

Shoghi Effendi himself leads us to further stages in the unfoldment of the Divine Plan, which continues to be propelled forward under the guidance of the Universal House of Justice. In this course we will learn the spiritual prerequisites for success of the Divine Plan, the teaching requirements, and the “double crusade” each Baha’i must conduct to “prepare . . . for the time when the Hand of Destiny will have directed them to assist in creating and in bringing into operation that World Order. . . .” As the Universal House of Justice wrote in its December 29, 2015, letter: This is an urgent call for action—“the urgency . . . impelled by the world’s desperate condition.”
