Ok let's begin. I don't know who Joel Hemphill's or Lehman Strauss is, I searched the bible and couldn't find their names?
Let's start from scratch here about the topic?
This is not about praying in tongues which really should be worded as praying in the Spirit and is a different concept of itself!
Next let's drop all the things we have been taught about the subject. We need to approach the Scripture concerning this topic with no preconceived ideals about what the Bible says. Only then can we travel back in time and understand what the Holy Spirit really says and then let Him explain it to us in our time!
