To the mounting tide of trials which laid low the Báb, to the long-drawn-out calamities which rained on Bahá’u’lláh, to the warnings sounded by both the Herald and the Author of the Bahá’í Revelation, must be added the sufferings which, for no less than seventy years, were endured by ‘Abdu’l-Bahá, as well as His pleas, and entreaties, uttered in the evening of His life, in connection with the dangers that increasingly threatened the whole of mankind. Born in the very year that witnessed the inception of the Bábí Revelation; baptized with the initial fires of persecution that raged around that nascent Cause; an eyewitness, when a boy of eight, of the violent upheavals that rocked the Faith which His Father had espoused; sharing with Him, the ignominy, the perils, and rigors consequent upon the successive banishments from His native-land to countries far beyond its confines; arrested and forced to support, in a dark cell, the indignity of imprisonment soon after His arrival in Akká; the object of repeated investigations and the target of continual assaults and insults under the despotic rule of Sulṭán ‘Abdu’l-Ḥamíd, and later under the ruthless military dictatorship of the suspicious and merciless Jamál Pá_sh_á—He, too, the Center and Pivot of Bahá’u’lláh’s peerless Covenant and the perfect Exemplar of His teachings, was made to taste, at the hands of potentates, ecclesiastics, governments and peoples, the cup of woe which the Báb and Bahá’u’lláh, as well as so many of their followers, had drained. With the warnings which both His pen and voice have given in countless Tablets and discourses, during an almost lifelong incarceration and in the course of His extended travels in both the European and American continents, they who labor for the spread of His Father’s Faith in the Western world are sufficiently acquainted. How often and how passionately did He appeal to those in authority and to the public at large to examine dispassionately the precepts enunciated by His Father? With what precision and emphasis He unfolded the system of the Faith He was expounding, elucidated its fundamental verities, stressed its distinguishing features, and proclaimed the redemptive character of its principles? How insistently did He foreshadow the impending chaos, the approaching upheavals, the universal conflagration which, in the concluding years of His life, had only begun to reveal the measure of its force and the significance of its impact on human society?
