Dr Koons.
If you think that Charismatics are wrong in the way they use the gift of tongues, how do you explain a friend of mine who had never been to Africa, praying in a prayer meeting, and a Ghanaian brother heard my friend speaking the praises of God and encouraging words in his own village dialect? My friend was merely speaking in tongues as Charismatics do, and yet he spoke an understandable language. If this can happen someone speaks in a tongues language by faith in this situation, then it is strong evidence that any Charismatic who speaks in tongues in the same way is speaking an articulate language that, if no-one else understands it, God certainly does and appreciates it.
When I was part of a Charismatic church, I was praying in tongues in a service, just quietly, and a lady sitting beside me told me that God spoke to her through me in the Maori language. I had no idea that I was speaking that language. I was just praying in tongues as all Charismatics do.
This testimony is just one of hundreds of similar testimonies. Are all these people lying? Or are you out of step with what is actually happening in the Holy Spirit among many groups of people who are worshiping God in a way that is out of your personal experience.
So your arguments against the current use of the gift of tongues by modern Charismatics falls flat in the face of two reliable witnesses.
