I read also that the purpose of the gift was to have the apostles teach in other languages.<quoted text>
I do not think that there is a human alive that understands everything about God or the way He thinks. But we are held accountable for the knowledge that we do have. I have learned of many commandments from God and I must, therefore, do my best to obey them, or I would be knowingly sinning.
I believe that the purpose of the gift of tongues is to teach the gospel to others. At the Pentecost I think it was more to prove to people the power of God. This is not its main purpose today.
I believe it is more manifest in being able to learn an entirely different language in a matter of a couple of weeks, to travel to the country that speaks this language and be fully immersed, and be able to teach the gospel of Jesus Christ in their native language.
I read the bible shows apostles was given the gift of tongues had the ability to speak many different tongues instantly, rather than two weeks of missoniary training for just one.
That said, it is impressive to learn a language as fast as two weeks.
I read this on a link covering the MTC. Not trying to split hairs here, but looks like many already had prior training in a language before attending MTC.
"In many cases, missionaries who already speak the language of their assigned area are sent to their mission after just three weeks."
I know you may believe your LDS students may have the gift of tongues, I would have to agree if they can learn it in two weeks of study and practice.
All due respect it is not a gift of tongues shown in the bible.
p.s. Glossolalia is fake I believe and used to con people and build a following.
