My dear , Srila Prabhupada explained in a room conversation in Bombay, India on 15 April 1977:
"Every one of us messiaḥ. Anyone Krishna conscious, he's the messiaḥ. Every one. Why one? All of us."
And then he quoted the Vaisnava poet Sri Devakinanda Dasa:
"Gaurāṅgera bhakta-gaṇe jane jane śakti dhare. The devotee of Lord Caitanya, every one has so immense power that every one, they can deliver the whole universe."
He has written in his purport to Sri Caitanya Caritamrita, Madhya Lila, Chapter 24, Text 25:
"Gaurāṅgera bhakta-gaṇe jane jane śakti dhare. The purport of this song is that the devotees of Lord Śrī Caitanya Mahāprabhu are very powerful, and each and every one of them can deliver the whole world."
So what does means for those who have fully dedicated their lives to Krishna? They are messiahs, world saviors, and their mission is to deliver the world from its present most hellish nightmarish condition by making everyone Krishna conscious.
