The Spirit of Prayer (1825) was the last work published by the evangelical reformer and author Hannah More. While it is specifically a work of Christian evangelical devotion, The Spirit of Prayer offers an accumulated reflection of More’s lifelong activism in moral and social reform. Moreover, the work reflects the defining characteristics of the evangelical movement that was gaining increasing influence during More’s lifetime. Yet, it also confirms More’s lifelong commitment to the Church of England. The views of prayer More details exemplify a Christian faith understood to be both “a religion of the heart” (More, Hannah, The spirit of prayer. In: The works of Hannah More, Henry G. Bohn, 1853, 376) and one of practical application and action within the world. The Spirit of Prayer displays More’s passions for children’s education and virtue ethics, which were of particular interest to her. While one of her least considered works today, The Spirit of Prayer is a work of theological rigor and literary craftsmanship that offers valuable insights into a literary figure worthy of renewed attention.
