Tozer writes from the heart about things of the Spirit of God. There is too little on the subject. In some aspects, he misses the mark on how the Holy Spirit operates, being influenced by his theological training. Most of his book is well-based on sound observation from his life experience in an area that is most important for the disciple. This book is a crucial addition to the library of any serious student of God. I strongly recommend it to everyone.
This is an excellent book that I highly recommend. Somewhat like Andrew Murray's Humility, the language is a bit archaic, but once you become familiar with the different sound, and dig into the content, it is vital and relevant. Chapter 3 is a favorite!
This is an incredible book. It was recommended to me at a time when I was looking to deepen my relationship with the Lord, to walk with Him daily. This book was instrumental in beginning that walk. This is a must read for anyone who seeks to be more than a casual Christian.
