Tongues, as practiced today by the false teachers the bible so clearly warns us about are a lie straight out of the pit of hell.
Paul made it abundantly clear in 1st Corinthians 13 that "Love never fails. But whether there are prophecies, they will fail; whether there are tongues, they will cease; whether there is knowledge, it will vanish away."
Paul makes it abundantly clear that the miraculous sign gifts were temporary.
The giving of the gift of prophecies will end.
The giving of the gift of tongues will end.
The giving of the gift of knowledge will end.
"9 For we know in part and we prophesy in part. 10 But when that which is perfect has come, then that which is in part will be done away."
The early church, in Paul's day, only had a partial revelation through tongues, prophecy, and knowledge.
But when the perfect (complete) (revelation) came, the partial (revelation in the form of tongues, prophecy, and knowledge) was done away with.
When the complete revelation, in the form of the Holy Bible, was completed the sign gifts went away.
"11 When I was a child, I spoke as a child, I understood as a child, I thought as a child; but when I became a man, I put away childish things."
Paul says those sign gifts were only for the infancy of the church, but when the church reached maturity, with a finished bible, the toys of childhood were set aside.
"12 For now we see in a mirror, dimly, but then face to face. Now I know in part, but then I shall know just as I also am known."
Now we can look into the "Perfect Law of Liberty" - the bible - and see ourselves as we really are, our partial understanding, given through tongues, prophecy and knowledge, has been replaced by the mature, complete knowledge we have from the bible, and we can know the thoughts of God, from the bible, just as He has always known ours.
"13 And now abide faith, hope, love, these three; but the greatest of these is love."
Notice Paul says, at the time of the writing of 1st Corinthians, the gifts of tongues, prophecy and knowledge were no longer being given to new converts, so he says "now abide faith, hope, and love, these three." He did NOT say, "now abide faith, hope, love, tongues, prophecy, and knowledge, these six." To suggest the sign gifts are still active is to call Paul a liar, to call the bible a lie, and to call the Holy Spirit of God, Who inspired the bible, a liar.
To call God a liar is the worst form of blasphemy.
