Well-known Christian author George MacDonald is no stranger to spiritual literature, whether it be fiction or nonfiction. Unspoken Sermons, a collection of essays intent on understanding both theology and faith itself, not just God, is an honest look at what MacDonald refers to as the balance between ‘childish heart’ and ‘righteous duty.’

This edition includes the sermon he gave on the topic of 'proving the unseen' which he preached in June of 1882, with the title "Faith, the Proof of the Unseen."

Unspoken Sermons is not a complete change of pace from his beloved children’s fantasy novels, which are known for their didactic nature. MacDonald is highly praised for his ability to include lessons in faith in stories that entertain and fulfil children, and despite the non-fictitious genre, the essays are easily digestible for those looking for answers to their questions in belief.

Unspoken Sermons consists of three series, all of theological impact, which has influenced many religious literary geniuses such as Lewis Carroll, G. K. Chesterton, and even Tolkien. C.S. Lewis regarded him so highly that MacDonald appeared as an important character in Lewis's book, The Great Divorce.

Macdonald’s Unspoken Sermons focuses on the on the development of love between the person and God, looking to inspire others to do the will of God rather than just believe the truth about God. With this, Macdonald has created something that will continue to motivate people, even those who are not religious, to concentrate less on dogma and more on love.
