... a Force ...

The field is indeed so immense, the period so critical, the Cause so great, the workers so few, the time so short, the privilege so priceless, that no follower of the Faith of Baha'u'llah, worthy to bear His name, can afford a moment's hesitation. That God-born Force, irresistible in its sweeping power, incalculable in its potency, unpredictable in its course, mysterious in its workings, and awe-inspiring in its manifestations -- a Force which, as the Bab has written, "vibrates within the innermost being of all created things," and which, according to Baha'u'llah, has through its "vibrating influence," "upset the equilibrium of the world and revolutionized its ordered life" -- such a Force, acting even as a two-edged sword, is, under our very eyes, sundering, on the one hand, the age-old ties which for centuries have held together the fabric of civilized society, and is unloosing, on the other, the bonds that still fetter the infant and as yet unemancipated Faith of Baha'u'llah. The undreamt-of opportunities offered through the operation of this Force -- the American believers must now rise, and fully and courageously exploit them. "The holy realities of the Concourse on high," writes 'Abdu'l-Baha, "yearn, in this day, in the Most Exalted Paradise, to return unto this world, so that they may be aided to render some service to the threshold of the Abha Beauty, and arise to demonstrate their servitude to His sacred Threshold."
