Let not man glory in this that he loves his country, but let him rather glory in this that he loves his kind." Previous Prophets have heralded an age of peace on earth, goodwill among men, and have given Their lives to hasten its advent, but each and all of Them have plainly declared that this blessed consummation would be reached only after the "Coming of the Lord" in the latter days, when the wicked would be judged and righteous rewarded.
Zoroaster foretold three thousand years of conflict before the advent of _Sh_ah Bahram, the world-savior, Who would overcome Ahrman the spirit of evil, and establish a reign of righteousness and peace.
Moses foretold a long period of exile, persecution and oppression for the children of Israel, before the Lord of Hosts would appear to gather them from all the nations, to destroy the oppressors and establish His Kingdom upon earth.
Christ said: "Think not that I am come to send peace on earth: I came not to send peace, but a sword" (Matt.

x, 34), and He predicted a period of wars and rumors of wars, of tribulations and afflictions that would continue till the coming of the Son of Man "in the glory of the Father." Muhammad declared that, because of their wrongdoings, Allah had put enmity and hatred among both Jews and Christians that would last until the Day of Resurrection, when He would appear to judge them all.
Baha'u'llah, on the other hand, announces that He is the Promised One of all these Prophets--the Divine Manifestation in Whose era the reign of peace will actually be established.

This statement is unprecedented and unique, yet it fits in wonderfully with the signs of the times, and with the prophecies of all the great Prophets.

Baha'u'llah revealed with incomparable clearness and comprehensiveness the means for bringing about peace and unity amongst mankind.
It is true that, since the advent of Baha'u'llah, there have been, until now, war and destruction on an unprecedented scale, but this is just what all the prophets have said would happen at the dawn of the "great and terrible Day of the Lord," and is, therefore, but a confirmation of the view that the "Coming of the Lord" is not only at hand, but is already an accomplished fact.

According to the parable of Christ, the Lord of the Vineyard must miserably destroy the wicked husbandmen before He gives the Vineyard to others who will render Him the fruits in their seasons.
