God gave those in the upper room the ability to speak in other tongues so that they could preach in the language that would be understood by their audience. Those who would try to impress with using language other than that understood by the people they a speaking to are contrary to that concept of the upper room gift given by the Holy Spirit. Those who think for some reason that using some language other than that spoken by the people they are speaking to is somehow more holy or something are more akin to those people who were building the tower of Babel than those in the upper room. Shack the dust.
Thanks. I’m shacking, baby!
