I would like to know a quote that supports how Scrooge has changed in A Christmas Carol.

Although Ebenezer Scrooge begins to show changes as early on as Stave II when the Ghost of Christmas Past shows him Fezziwig's holiday party, the real changes that we see come toward the end of the story in Stave V, after Scrooge has awakened on Christmas Day.

Scrooge spends Christmas essentially making amends. He commits money to the charity he had refused at the beginning of the story. He visits his nephew Fred for Christmas...

Although Ebenezer Scrooge begins to show changes as early on as Stave II when the Ghost of Christmas Past shows him Fezziwig's holiday party, the real changes that we see come toward the end of the story in Stave V, after Scrooge has awakened on Christmas Day.

Scrooge spends Christmas essentially making amends. He commits money to the charity he had refused at the beginning of the story. He visits his nephew Fred for Christmas and actually meets his wife. And most significantly, he visits the Cratchits, provides them with a huge turkey for dinner, and raises Bob's salary. Beyond that, we know this:

"Scrooge was better than his word. He did it all, and infinitely more; and to Tiny Tim, who did not die, he was a second father. He became as good a friend, as good a master, and as good a man, as the good old city knew, or any other good old city, town, or borough, in the good old world. Some people laughed to see the alteration in him, but he let them laugh, and little heeded them; for he was wise enough to know that nothing ever happened on this globe, for good, at which some people did not have their fill of laughter in the outset; and knowing that such as these would be blind anyway, he thought it quite as well that they should wrinkle up their eyes in grins, as have the malady in less attractive forms. His own heart laughed: and that was quite enough for him" (Stave V).

Clearly Scrooge has changed completely from the miserable man he was at the beginning of the story. He went form being utterly alone and greedy to part of two families and generous. He embraces life in every way. He also went from being a man no one respected (but they did fear) to a man that earned and gave respect to others.
