stowe's puritanical religious beliefs are also one of the biggest themes in the novel. she explores what christianity is like. she believed that the most important thing in christianity was love for everyone. she also believed that christian theology shows that slavery is wrong. this theme can be seen when tom urges st. clare to "look away to jesus" after st. clare's daughter eva dies. after tom dies, george shelby says, "what a thing it is to be a christian." because christian themes are so important, and because stowe often directly spoke in the novel about religion and faith, the novel is written in the "form of a sermon."
