Although the topic of tongues has been covered in many books, this little book stands out, because it has new things to say and breathes new life into a discussion Christians have been having for decades. Not in "addition" to scripture, but letting all-scripture, rather than denominational opinions form new answers. No matter how much you've studied, either pro or con, you'll be surprised to find original thoughts due to the author's original way of thinking, uncluttered by denominational biases, but letting the Word of God systematically speak for itself.
