Both the play A Raisin in the Sun and the novel The Secret Life of Bees relate to the quotation by Martin Luther King, Jr. in the development of major characters in the stories. In A Raisin in the Sun, Mama buys a house in a white neighborhood because she thinks that it will be comfortable for her family. She and her family know that they will have a difficult time melding into the culture of the new community and that they will likely experience discrimination while they are there. However, Mama insists that they all move, believing that they are all strong enough to deal with any hardship. Through this decision, Mama shows her inner strength and determination.
Similarly, in The Secret Life of Bees, Lily ends up living with the Boatwrights because she is having trouble living with her father. While at the Boatwrights' home and out of her own element, Lily begins to learn about people and relationships, particularly after May's suicide. As the family grieves, Lily decides to use May's wall as a place of redemption and prayer. So, she shows her character through this challenging time.
So both stories exhibit characters who "shine" during their most challenging moments.
