I know that's what you said.
"Modern day tongues" are tongues.
You're repeating yourself.
Modern days tongues today as a diversity of known language is accomplished by a electronic deivce as a real time translator used between two different languages . When two people get to together of different languages using that device neither will be a Barbarians to the other.... like a reversal of the tower of Babel.
There are, it may be, so many kinds of voices in the world, and
none of them is without signification. Therefore if
I know not the meaning of
the voice,
I shall be unto
him that speaketh
a barbarian, and
he that speaketh shall be a barbarian unto
me.1 Corinthians 14:10-11
The gospel is a two way stret a mutual gift that works in both, the hearer and the speaker, or speaker and the hearer .Mutually edifying God who does the all the work.
The new device today is all we have. Other then people going to school to learn other languages. I think God alone knows all the langue's of the world some people know a few like 7 or so if there memories serve them .
Because new revelations, as prophecy a has ceased, ….tongues God's interpretation (inspiration) in many languages other than the Hebrew alone have also ceased.
Why go above that which is written and ignore the warning not to?
