y,
the All-Knowing! He hath come to minister to the life of the
world, and for the uniting of whatever dwelleth therein. Come, O
ye people, to the Dawning-place of Revelation! Tarry not, even for
an hour! Are ye learned of the Gospel, and yet are unable to see
the Lord of Glory?

This beseemeth you not, O learned concourse! Say then, if ye deny
this matter, by what proof do you believe in God? Produce your
proof....

Just as in these letters to Christians He announces the fulfillment of the
Gospel promises, so He proclaims also to Muhammadan, Jews, Zoroastrians

removing the barriers between them, that "there may be one fold and one
shepherd."

A New Situation

The position of Baha'u'llah 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 Baha'u'llah 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 adopte
