In this book, we will explore the mystery of the thorn in the flesh. Paul stated that God had given him a thorn in his flesh in order to keep him humble because of the revelation that was in his life. However, there has been much controversy over what the thorn in his flesh was, and how God could allow such a thing to exist. In addition, there are Christians claiming that certain afflictions in their lives are a 'thorn in the flesh,' when they may not be. Therefore, we will endeavor to bring understanding to these concerns and discover what impact this has upon the believer today.
