It would be interesting to understand how and why the Lubabitcher chassidim bought into the notion about their Rebbe being the Mashiach.
What has he done, in their point of view, to make them believe in their Rebbe so much, to say that he is the Mashiach?
For those that believe that he is still alive (literally or spiritually), what has he done that is so deserving of giving him this status, especially when compared to other previous tzadikim or Prophets?
