This book was written by Artuhr Pink. I'm not really sure of his doctorinal persuasion, but this book--actually two statments---have changed the way i pray.1)If the Glory of God is not your foremoset concern in prayer, then you are praying amiss. 2)Praying is preaching to yourself in the presece of God. It is for your edification not His information.I actaully happen across this book while searching for some commentary on the Lord's Prayer (which is the MOST powerful prayer in all the Word!). It was a blessing.
