Hey, if, in the 21st Century, Christians want to believe they can speak in tongues, despite that they’re own bible says (or at least implies) that they can’t and definitely says they shouldn’t, that’s their business.
Where does it say (or imply) that?
1 Corinthians has a bit of a diatribe against it. Funnily enough, the most condoning that it says about it is that if no one can understand what you’re saying then you should keep it to yourself.
