But like so many people, you do not seem to really look at the words in the scriptures...You just read 'em and let someone else tell you what they mean...Consider this:
1Co 14:13 Wherefore let him that speaketh in an unknown tongue pray that he may interpret.
Here, the speaker CHOSE to speak in an unknown tongue...A tongue that he, the speaker doesn't know...
Can you chose to speak Russian if you do not know the language??? Or Chinese???
The Apostles in acts didn't chose to speak in foreign languages...THAT was a special revelation from God...
But here, the person chose to speak a language that he doesn't know...How can that be???
And then Paul says the person should pray to know how to interpret what the person just said...
Would seem that it could not then be a foreign language...
