It [The Advent of Divine Justice] was written during the year the Guardian remained in Europe owing to terrorist activities in Palestine, and was addressed to the Bahá'ís throughout the United States and Canada. In it Shoghi Effendi set forth, as never before, the role this Community was destined to play in the unfolding destiny of man on this planet. It defined the objectives of the recently opened Seven Year Plan, the first step in implementing the provisions of 'Abdu'l-Bahá's Divine Plan, and pointed out that upon the success of this greatest joint enterprise ever undertaken by Bahá'u'lláh's followers must depend the fate of all future activities in the promulgation of His world Order throughout the other continents of the globe. With a kind but firm hand Shoghi Effendi held up before the face of the North American Community the mirror of the civilization by which they were surrounded and warned them, in terms that riveted the eye and chilled the heart, against its evils, pointing out to them a truth few of them had ever pondered, namely, that the very evils of that civilization were the mystic reason for their homeland having been chosen by God as the Cradle of His World Order in this day. As the warnings contained in The Advent of Divine Justice are an integral part of the vision and guidance Shoghi Effendi gave tot he faithful throughout his ministry, they cannot be passed over in silence if we are to obtain any correct understanding of his own mission. In no uncertain terms he castigated the moral laxity, political corruption, racial prejudice and corrosive materialism of their society, contrasting it with the exalted standards inculcated by Bahá'u'lláh in His Teachings, and enjoined by Him upon His followers. It warned them of the war so soon to come and admonished them to stand fast, in spite of every trial that might in future afflict them and their nations, and discharge their sacred trust by prosecuting to a triumphal outcome the Plan they had so recently inaugurated throughout the Western Hemisphere.
