ricky could you post one single video of a tongue talker that you think is for real?
could you help determine the difference between the real and the fake.?
otherwise we are only left to take your word for it.
While I can't say this with 100% certainty, I would suspect that anyone doing it in front of a camera would be faking it. 'Prayer tongues' are to be done in private, between you and God. Which is one reason I'm not a big fan of the pentasmics thing. They forget this. They're the reason Paul wrote about time and place in 1 Cor 14.
Keys to discernment are, 1 does it glorify God, and 2 does it edify the speaker.
Look, I understand there are fakes, if I had to venture a guess I'd say they out number the genuine uses. I also understand that anyone pushing them on others (pushing, not explaining) is fake as well.
A couple days ago my wife and I were decorating her mom's church (Lutheran Missouri Synod) and the deacon said "I'd go to a pentecostal church but I don't want to speak in tongues". I told him that if they insist he does he should walk out.
God never said you have to. He just said you should be open to it, and do it right or don't do it at all.
