The Corinthians had the "gift" of tongues and they were misusing it greatly. That's why Paul had to correct them.
Like for instance .Do something Jesus then we will believe something (mockery ) Sings and wonders are for those who rebel against prophecy . The evil generation .(no faith) just a whole lot of noise.
John 4:48 Then said Jesus unto him, Except ye see signs and wonders, ye will not believe.
Luke 11:29 And when the people were gathered thick together, he began to say, This is an evil generation: they seek a sign; and there shall no sign be given it, but the sign of Jonas the prophet.
Spiritual gift yes working from within .Edifying the unseen Spirit.
Our new born again tongue prophecy "the gospel" as the power we have in us it can drive out the idea of senseless sounds . Saw lasaw saw lasaw. Qaw laqaw qaw laqaw. Ze’er sham ze’er sham.
So God will use this "strange way" of talking, and he will use other languages to speak to these people. In the past he spoke to them and said, “Here is a resting place. Let those who are tired come and rest. This is the place of peace.” But they would not listen to him. So the Lord’s words will be "senseless sounds" to them:
“Saw lasaw saw lasaw.
Qaw laqaw qaw laqaw.
Ze’er sham ze’er sham.”
When the people try to walk, they will fall backwards. They will be defeated, trapped, and captured. Isaiah 28
