The best stories have character development. This is where a character changes throughout the events of the story. For example, the 2008 blockbuster movie Iron Man starts out with playboy Tony Stark, an egotistical, rich genius who is kidnapped by terrorists. While imprisoned, he learns that his weapons are being used by terrorists to harm innocent people. He escapes and later becomes Iron Man, the superhero. He still has an ego but has developed into a person who fights for others. Sanctification creates that kind of change in our life story. It radically changes who we are.
