This book is powerful in the sense that every time my sister read it to me over the phone I felt the Lord was speaking to me on the very day that I read it and I received it by faith. I got so excited about at first my sister bought another for me and sent it to me in chgo. It seemed like the words came alive as if the author literally pray and fasting for this book for ppl to encounter God each and every time they opened this book and read that day devotional. WOW!! I love it
