Are you sure that that is how the gift of SUPERNATURALLY speaking in a foreign language works? Here is what we actually see: And they were all amazed and marvelled, saying one to another, Behold, are not all these which speak Galilaeans? And how hear we every man in our own tongue [LANGUAGE], wherein we were born? Parthians, and Medes, and Elamites, and the dwellers in Mesopotamia, and in Judaea, and Cappadocia, in Pontus, and Asia, Phrygia, and Pamphylia, in Egypt, and in the parts of Libya about Cyrene, and strangers of Rome, Jews and proselytes, Cretes and Arabians, we do hear them speak in our tongues [LANGUAGES] the wonderful works of God.
(Acts 2:7-11).
Why did Paul insist that there be an interpreter for anyone attempting to speak a foreign language supernaturally? Because a strange language needs to be interpreted to make sense.
