I liked this book a lot. Even though it's old, and some of its topics were not that relevant to me, the overall message of living meeting Christ in our neighbors touched me and felt right. Quoist captures the full nature of salvation perfectly in the many examples that go well beyond what is often meant by salvation.
The book is not perfectly written, and it's not scientific theology by any means, but it's powerful in its message. If more Christianity lived their faith according to what is taught in this book, the world would be a much better place.
