I especially take notes on chapter 3, " The Struggle For Prayer" how Osward Chambers display the picture of the realm of prayer in the Holy Spirit, and only in that realm, there is no snares, he explains that because it is base on the redemption of the Lord Jesus Christ made efficacious all the time by the Holy Spirit.
Possibly the best book I have ever read on the subject of prayer. I learned of it when I found it on the "recommended reading" list published by Dr. Henry Blackaby, author of "Experiencing God," on the Blackaby Ministries International website. My recommendation: Read it. You'll be glad you did!
