November 18

The twentieth century has been distinguished by the emergence of the unity of nations, to which both Shoghi Effendi and the House of Justice have referred in the enclosed document. This movement, the evidence of which accumulates with each passing day, stands in sharp contrast to the nationalistic tenor of the nineteenth century, and is an evidence of the spirit of a new age moving in the hearts of humankind. Viewed from this perspective, there can be no doubt that the promise of ‘Abdu'l-Bahá has been fulfilled, and the unity of nations securely established in the century now concluded. The further expansion and strengthening of this consciousness of world solidarity in the years to come will have their effect in the political realm, and will influence the evolution towards world government.

It should not be imagined that the processes now moving in the world will be free from challenge or difficulty. There may well be set-backs, and conflicts may erupt periodically, as humanity proceeds towards the emergence and consolidation of the Lesser Peace, giving rise in due course to the establishment of the Most Great Peace.
