What was the change that Christmas morning brought in Scrooge?

When Scrooge woke up on Christmas morning, he was a changed man. He had joy in his heart, and he vowed to live by the lessons the spirits taught him. He immediately began to share his wealth with those in need..... he was charitable, kind, and amiable to those he met on the street. He even gives Bob Cratchit a raise and takes Tiny Tim under his wing.... becoming a second father to the little boy and making sure he has the best medical care he can receive.
