Yours, Jack: Spiritual Direction with C. S. Lewis. This is a book of selected letters of C. S. Lewis, whom close friends knew as Jack. Already within the first 20-30 pages I have found a few spiritual truths that are worth the price of the book. It also offers some insights into Lewis himself. I have just read, in one of his early letters, of a conversation he had with friends Hugo Dyson and J. R. R. Tolkien that turned out to be pivotal in his conversion to Christ.
There are three kinds of letters in this book, moving chronologically through Lewis' spiritual development. The first are letters of spiritual companionship, followed by letters of discipleship in which he asks for spiritual advice. The last are letters of spiritual direction, in which he answers those who have asked him for spiritual advice.
This is indeed a book to relish.
