Just as in these letters to Christians He announces the fulfillment of the Gospel promises, so He proclaims also to Muḥammadan, Jews, Zoroastrians and the people of other faiths the fulfillment of the promises of their Holy Books. He addresses all men as the sheep of God, who have hitherto been divided into different flocks and sheltered in different folds. His message, He says, is the Voice of God, the Good Shepherd, Who has come in the fullness of time to gather His scattered sheep into one flock, removing the barriers between them, that “there may be one fold and one shepherd.” A New Situation The position of Bahá’u’lláh among the Prophets is unprecedented and unique, because the condition of the world at the time of His advent was unprecedented and unique. By a long and checkered process of development in religion, science, art and civilization the world had become ripe for a teaching of Unity. The barriers which in previous centuries had made a world unity impossible were ready to crumble when Bahá’u’lláh appeared, and since His birth, in 1817, and more especially since the promulgation of His teachings began, these barriers have been breaking down in most astonishing fashion. Be the explanation what it may, about the fact there can be no doubt. In the days of previous Prophets geographical barriers alone were amply sufficient to prevent world unity. Now that obstacle has been overcome. For the first time in human history men on opposite sides of the globe are able to communicate with each other quickly and easily. Things done in Europe yesterday are known in every continent of the world today, and a speech made in America today may be read in Europe, Asia and Africa tomorrow. Another great obstacle was the language difficulty. Thanks to the study and teaching of foreign languages, that difficulty has already been to a large extent overcome; and there is every reason to suppose that ere many years an international auxiliary language will be adopted and taught in all the schools of the world. Then this difficulty also will be completely removed. The third great obstacle was religious prejudice and intolerance. That, too, is disappearing. Men’s minds are becoming more open. The education of the people is passing more and more out of the hands of sectarian priests; and new and more liberal ideas can no longer be prevented from penetrating into even the most exclusive and conservative circles. Bahá’u’lláh is thus the first of the great Prophets Whose message has become known within a period of comparatively few years in every quarter of the globe. Within a short time the essential teachings of Bahá’u’lláh, translated from His own authentic Writings, will be directly accessible to every man, woman and child in the world who is able to read.
