Imitation of Christ by Thomas A. Kempis (1952, Paperback)

Todd Agnew suggested this book as a cornerstone of Christian belief. I totally agree that it challenges you as a Christian to walk the path of Jesus and learn to be more like Him. It works on your heart and at times it is hard to get past a certain point, but I have come to realize that these are places where I struggle in my own walk. It is probably not for the new Christian, I would suggest reading the Bible first, but I haven't found a book that puts the expectations of Christ in such plain language. It is a hard hitting explanation of what God expects of us as His children, and gives very clear instruction of how to do so. I love this book, and recommend it to you.
