Six years ago, I wrote my dissertation on who the Holy Spirit is in order to obtained my doctorate degree. I chose a topic that not one faculty member at Bethel Christian College had written on. The reason why I chose this topic is that one day, one of my children asked me a question about who the Holy Spirit is, and that is how this came to birth. I wondered, since my children asked me so many questions about the Holy Spirit, how many other Christians had the same questions but were afraid to ask. What I learned from researching on this topic was that very little was written on this subject. So after completing my dissertation, I wanted to share what I learned and discovered with others. The more I put it off, the more restless I became. It has taken me nine years to complete this task. There are four questions I will be addressing in the book: 1. Who the Holy Spirit is 2. The Holy Spirit and spiritual growth 3. The Holy Spirit and the nine fruit of the Spirit 4. The silent active roles the Holy Spirit had in the Old Testament
