Lord Chaitanya did not advent Himself to liberate only a few men of India. Rather, His main objective was to emancipate all living entities of all countries throughout the entire universe and preach the eternal religion. Lord Chaitanya says in the Chaitanya-bhagavata: 
prithvite ache yata nagaradi grama
sarvatra prachara haibe mora nama
In as many towns and villages as there are on the surface of the earth, My holy name will be preached. (Chaitanya Bhagavata, Antya-khanda 4.126)
There is no doubt that this unquestionable order will come to pass. In the world now there are so many religious communities, and in their purest mature form they are the religion of singing the praises of the Lord. At the present time there is a great spiritual quest going on in the world, and it seems that one unalloyed religion which is the essence of all the religions will soon emerge. What is that religion? It is plain to see that in western countries and in Asia, religions are engaged in conflicts. There is no doubt that these religions will not be able to endure. Therefore many of the established religions which harbour prejudiced, conflicting beliefs have become fragmented. When all these contradictory dogmas are removed, it is then and there that all religions will be united. Let us consider what specifications the Eternal Religion would have: 

1. God is one and is the all-knowing source of knowledge. He is devoid of all limitations and is the reservoir of all qualities. 

2. All living entities are infinitesimal parts and parcels of consciousness, and the eternal function of all living entities is to serve the Supreme Lord. 

3. To sing the glorious qualities of the Supreme Personality of Godhead and to establish the brotherhood of all men is pure religion.
Gradually the established religions will then be removed of all specific contradictions, and the secular or 'party spirit' will not remain. Then all castes, all creeds and men of all countries will be united in coexistent brotherhood under the Supreme Personality of Godhead, united by nama-sankirtana. "Then and there, personal hereditary status will be considered insignificant, and inter-caste hatred will disappear, and the common brotherhood of man will never be forgotten. Then we will carry the vessel of the Nectar of Devotion of Haridasa, we will follow the words of Srivasa and smear our bodies with the dust of Their Feet. O Lord Chaitanya, Lord Nityananda, the human race will spontaneously dance in ecstasy.
Very soon the unparalleled path of hari-nama-sankirtana will be propagated all over the world. Already we are seeing the symptoms. Already many Christians have tasted the nectar of divine love of the holy name and are dancing with karatalas and mridangas. Educated Christians are ordering these instruments and shipping them to England. By the super-excellence of Lord Krishna's holy name and the grace of pure devotees, our consciousness gets purified. After listening to a lecture on these principles, a great gathering of brahmanas danced with drums and karatalas, singing, “Fill your eyes with the vision of the advent of the Two Holy Brothers (Lord Chaitanya and Lord Nityananda).”
Even the Salvation Army somehow or other has its form of kirtana. When I see these signs, my hopes of seeing Lord Chaitanya's aforesaid prophecy being fulfilled are quickened, and that time has arrived. Although there is still no pure society of Vaishnavas to be had, yet Lord Chaitanya's prophetic words will in a few days come true, I am sure. Why not? Nothing is absolutely pure in the beginning. From imperfection, purity will come about.
Oh, for that day when the fortunate English, French, Russian, German and American people will take up banners, mridangas and karatalas and raise kirtana through their streets and towns. When will that day come? Oh, for the day when the fair-skinned men from their side will raise up the chanting of “Jaya sachinandana, jaya sachinandana ki jaya!” and join with the Bengali devotees. When will that day be? On such a day they will say, 'Our dear Brothers, we have taken shelter of the ocean of Lord Chaitanya's Love; kindly embrace us.' When will that day come? That day will witness the holy transcendental ecstasy of the vaishnava-dharma to be the only dharma, and all the sects and religions will flow like rivers into the ocean of vaishnava-dharma. When will that day come?
