Think of the Earth is about a man, a wanderer, who feels a deep tie with Christ although they live continents and centuries apart. In fact, he becomes caught in a web of over-identifying with him and is convinced he is meant to become a sacrifice of the sort that relieves people of the guilt they carry around with them. It is this that gives his life fulfillment until he meets a preacher's daughter and feels the stirrings of love for another in his heart.
The reason I liked this novel so much was that it went overboard where religion was concerned and then pulled itself back. Nowadays a person doesn't read novels that deal with Christianity and heretical opinions unless they are in the religions aisle in a big book store or in a Christian media store looking at nonfiction. The book surprised me for where the philosophy went and where it ultimately ended up. It was a nice change. Eight out of ten bookmarks.
