I was given this little book to read the night I received the Holy Spirit and began speaking in tongues. It has helped me greatly to understand the Scriptures and the different kinds of "tongue-talking" described in the Bible. Very helpful for this Baptistcostal! I now feel that many Scripture that previously didn't make sense and had to be explained away by many Southern Baptist preachers & teachers have fallen into place perfectly. It's so clear when you can just take the Scriptures literally.
