It would be helpful to know what exactly the author of the book seems to think tongues are - can you perhaps elaborate on his/her conclusions?? The summary on Amazon does not address this.
Speaking in tongues is very simple to understand through the concepts presented in this writing, but impossible to know without these concepts because of today’s teaching, understanding, interpretation of scripture and even the Bible itself because the translators base their translation--not on what tongues are, but on the common belief of tongues, and if this belief is incorrect so also the translation; and therefore again it may not be possible to ever know the true meaning of tongues or what it means to speak in tongues without the teachings and concepts in this book because it shows where the faults in our interpretation and translation lie.
