But in regards to tongues consider the following verses. In fact consider the whole chapter. Further consider the whole chapter of every verse I've brought up thus far! Prove me wrong, your study will delight both the Lord and myself, especially if I am wrong, as then I'll learn something!
1Co 14:2 For he that speaketh in an [unknown] tongue speaketh not unto men, but unto God: for no man understandeth [him]; howbeit in the spirit he speaketh mysteries.
1Co 14:14 For if I pray in an [unknown] tongue, my spirit prayeth, but my understanding is unfruitful.
1Co 14:15 What is it then? I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also.
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...
