The Supreme Manifestation
Like all the other Prophets, Baha'u'llah states His own Mission in the most unmistakable terms. (82:4)

In the Lawh-i-Aqdas, a Tablet addressed especially to Christians, He says:
Surely the Father hath come and hath fulfilled that which you were promised in the Kingdom of God. This is the Word which the Son veiled when He said to those around Him that at that time they could not bear it. But when the stated time was ended, and the Hour arrived, the Word shone forth from the Horizon of the Will. Beware, O Concourse of the Son (i.e. Christians)! Cast it not behind you, but hold thereunto. It is better for you than all that which is before you! .. Verily, the Spirit of Truth is come, to guide you into all Truth. Verily, He speaketh not from Himself, nay, but rather from the All-Knowing and Wise. He is the One Whom the Son hath glorified.. Abandon that which is before you, O people of the earth, and take that which is commanded you by Him Who is the Powerful, the Faithful. (82:5)

And in a letter to the Pope, written from Adrianople in 1867, He says:
Beware lest celebration hinder you from the Celebrated and worship hinder you from the Worshipped One! Behold the Lord, the Mighty, 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? (82:7)

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.. (83:1)

Just as in these letters to Christians He announces the fulfillment of the Gospel promises, so He proclaims also to Muhammadan, 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." (83:2)

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. (83:3)

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. (83:4)

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. (83:5)

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. (83:6)

Baha'u'llah 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 Baha'u'llah, translated from His own authentic Writings, will be directly accessible to every man, woman and child in the world who is able to read. (83:7)
