The main theme in this book is Salvation. There are 23 different routines but they all directly or in directly relate to knowing Christ as one's Savior. How to tie the balloons, what balloons to use and what to say is included in each routine. These are really clever and almost become an illusion as silks suddenly appear from inside an inflated and tied balloon or a black and white balloon can appear to become one balloon 1/2 black and 1/2 white. If you are a balloonatic, this book is for you.
