I find this book difficult to follow. Navigation to a particular verse in the bible is difficult to find. One has to read from the beginning of the chapter until you get to the verse you are looking for.reference verses are all over the place. The whole thing is just not coherent and makes it completely useless as a biblical reference book.It is not worth the money spent. I would be glad if I would get a refund. Meanwhile I am going to remove it from my kindle.
