On April 16, 1912, a group of Baha'is from New Jersey journeyed to New York City. There they listened to a talk, one that was presented by Abdu'l-Baha. Here is one paragraph from that talk:
"The body of the human world is sick. Its remedy and healing will be the oneness of the kingdom of humanity. Its life is the Most Great Peace. Its illumination and quickening is love. Its happiness is the attainment of spiritual perfections. It is my wish and hope that in the bounties and favors of the Blessed Perfection we may find a new life, acquire a new power and attain to a wonderful and supreme source of energy so that the Most Great Peace of divine intention shall be established upon the foundations of the unity of the world of men with God. May the love of God be spread from this city, from this meeting to all the surrounding countries. Nay, may America become the distributing center of spiritual enlightenment, and all the world receive this heavenly blessing! For America has developed powers and capacities greater and more wonderful than other nations. While it is true that its people have 20 attained a marvelous material civilization, I hope that spiritual forces may animate this great body and a corresponding spiritual civilization be established. May the inhabitants of this country become like angels of heaven with faces turned continually toward God. May all of them become the servants of the Omnipotent One. May they rise from present material attainments to such a height that heavenly illumination may stream from this center to all the peoples of the world. "
The above paragraph can be found in the book The Promulgation of Universal Peace.
