In his C.S Lewis's introduction to George MacDonald: An Anthology, he speaks highly of MacDonald's theology: "This collection, as I have said, was designed not to revive MacDonald's literary reputation but to spread his religious teaching. Hence most of my extracts are taken from the three volumes of Unspoken Sermons. My own debt to this book is almost as great as one man can owe to another: and nearly all serious inquirers to whom I have introduced it acknowledge that it has given them great help-sometimes indispensable help toward the very acceptance of the Christian faith...I know hardly any other writer who seems to be closer, or more continually close, to the Spirit of Christ Himself. Hence his Christ-like union of tenderness and severity. Nowhere else outside the New Testament have I found terror and comfort so intertwined...In making this collection I was discharging a debt of justice. I have never concealed the fact that I regarded him as my master; indeed I fancy I have never written a book in which I did not quote from him. But it has not seemed to me that those who have received my books kindly take even now sufficient notice of the affiliation. Honesty drives me to emphasize it." This collection brings together three of George MacDonald's writings: "Unspoken Sermons by George Macdonald Series i, ii, iii in One Volume" - expositions revealing his profound theology. "A Book of Strife in the Form of the Diary of an Old Soul" - a book of poems remarkable for their stirring portrayal of human emotions. And "The Hope of the Gospel" - MacDonald writes about the gospel and about what it means to be a Christian with great wisdom and understanding.
