This book will deepen any Christian intercessor's prayer life. The book proceeds through regions of the world and gives information on the unreachd people groups that live in these regions. The pictures will help you feel compassion for these peoples. I have used this book for a year now and I find that it has made my prayer life much more focussed on the nations. The prayer requests are specific to each group of people and make praying more accurate. If you desire to glorify God through prayer, this is the book for you!
