The title of this book reveals its central thesis, the way to effectively build God's kingdom is through "warfare with the Devil." According to Okoro, crushing the Devil involves taking the offensive, in prayer, against the demonic principalities and powers which are at war with God's kingdom. In his book, he expounds on the fight and the force we should use to get what is truly ours; blessings and prosperity. We must claim the gifts stolen from us by Satan, and retrieve them back into our lives. He gives us all the answers in this book, which is a good teaching for Christians and those trying to find their way to the Throne of Grace. Once you pick up this book, its hard for you to put it down. Your eyes are just opened to one thing after another. Filled with knowledge and TRUTH, every Christian and should have a copy of this book as their guide to warefare. I am an avid reader and this book has touched me in a way that not many books have. I especially like the chapter on "Preparation for Battle: The A-Z of spiritual warfare". Okoro's exhortation enabled me to walk away with the conviction that we must take seriously the fact that we are involved in spiritual warfare and, because evangelism treads on the enemy's turf, it must be accompanied by fervent prayer in order to produce great results. Scripturally well-balanced, the book is written in easy to read and understand layman's terms, with a user-friendly format, filled with practical application. I received new insight into spiritual warfare that will forever change my mindset. The emphasis given to prayer and holiness is commendable. I love it!! An ideal Birthday gift for a good friend.
