Desiring God is a John Piper classic. In it, Piper discusses why he is a Christian hedonist (a term he coined) and what that means. He explains how the ultimate thing in life is to glory in God and enjoy Him.
The book seems to repeat itself often, and can sometimes feel like Piper is talking in circles but if it is broken down into small amounts, it is definitely a good read. Numerous scriptures back everything Piper discusses up.
While this book is a classic, it is definitely a slow read as it needs to be digested in small portions. This is not a book to just read, it is a book to take in.
