Query: A Needed Book for Prayer

Jesus taught His disciples to pray always (Luke 18:1). He further gave only one request of His disciples, prayer for evangelism (Matthew 9:38; Luke 10:2). This book will help you to see the burden of the Lord for the nations. Every nation and known people group is found in the pages of this book. I have found no other book on praying for the nations like this book. Johnstone (and Operation Mobilization) give the disciple enough information to help us to pray for the gospel to be spread in every nation (Matt. 28:19).You and I may never have the chance to visit Saudi Arabia, Japan, or the tip of Argentina with the gospel of Christ but we can pray for these nations and ask the Father to open their eyes to the truth of the gospel (1 Timothy 2:1-6). And this book will help us in that process.
