In Charles Dicken’s A Christmas Carol, Jacob Marley, and the three ghosts that manifest, teach Scrooge a number of life lessons during their nocturnal visitation. Jacob Marley is tormented in the afterlife because of his miserly ways. The first ghost reminds Scrooge of Christmas scenes from his past, the second examines those of the present, and the third enlightens him to the future. As they look at scenes from his childhood and young adulthood, they see Scrooge as a neglected child who turns into a young businessman who loves money. Scrooge learns that his love for money cost him the chance to have a family as he sees his former girlfriend celebrating Christmas with her new family. As they examine the present Christmas, Scrooge sees home scenes of his employee Bob Cratchit. Although the family can barely make ends meet, they are happy with each other’s company as they celebrate a meager Christmas. The Cratchit family has concerns for the life of their son, Tiny Tim, who will die if he does not receive the proper medical care. Scrooge learns that family relationships and love are more important than the outward trappings of Christmas. The family is happy in their togetherness while Scrooge is alone and lonely. As they move into the future, Scrooge sees himself alone in death. He learns that he can change his ways and he does. He provides a raise for Bob Cratchit, care for Tiny Tim, and celebrates Christmas by taking to the streets and sharing his cheer.

There are many moral lessons to be gleaned from the story about the importance of relationships and human interaction, how to use money as a tool, and the ability to mend past discretions.
