Well, one of the key themes is the importance of kindness and the spirit of Christmas. In 'A Christmas Carol Novel', we see how Scrooge is so caught up in his greed and self - centeredness that he has forgotten what Christmas is really about. The story shows how he is visited by the spirits and gradually comes to understand that being kind to others, sharing, and having a giving heart is what makes Christmas so special. It's a theme that reminds readers of the true meaning of the holiday season.
The main theme is redemption. Scrooge, the main character, is a miserly and cold - hearted man at the start. Through the visits of the three spirits, he is given a chance to see his past, present, and future, which makes him realize the error of his ways and he ultimately transforms into a more kind - hearted and generous person.
