When Ebenezer Scrooge is visited by The Ghost of Christmas Present he is shown just how ill the boy really is, and that he will die unless he receives treatment (which the family cannot afford on the salary Scrooge pays Cratchit). When visited by The Ghost of Christmas Yet to Come, Scrooge sees that Tiny Tim has died. This, and several other visions, lead Scrooge to reform his ways. At the end of the story, Dickens makes it explicit that Tiny Tim does not die, and Scrooge becomes a "second father" to him.
In the story, Tiny Tim is known for the statement, "God bless us, everyone!" which he offers as a blessing at Christmas dinner. Dickens repeats the phrase at the end of the story; this is symbolic of Scrooge's change of heart.
