I just finished the book, "Alive in the Spirit: Experiencing the Presence and Power of God" by A.W. Tozer. This is a new book compiled from Tozer sermons by James L. Snyder. It is classic Tozer -- grounded in the Bible, and full of those one-liner quotes familiar to Tozer's writings. I highly recommend this book to any Christian, especially if you want to understand and deepen your walk with the Holy Spirit.
"We cannot walk with the Holy Ghost unless we agree to walk the way He walks and go in the direction He is going."
"I have learned to give the Holy Spirit all the time He needs to do whatever He wants to do."
"If you have read the Bible and not encountered the Living Word, you have not really read the Bible."
Tozer challenges us to let the Holy Spirit to work in and through us so that the Glory of God, not the feeble works of man, will shine forth.
