Stand far away from those who arise and babble and tell you it is the word of God, judgment can't be far from them.
1 Cor. 14:13-19 "Therefore let one who speaks in a tongue pray that he may interpret. For if I pray in a tongue, my spirit prays, but my mind is unfruitful. What is the outcome then? I will pray with the spirit and I will pray with the mind also; I will sing with the spirit and I will sing with the mind also. Otherwise if you bless in the spirit only, how will the one who fills the place of the ungifted say the "Amen" at your giving of thanks, since he does not know what you are saying? For you are giving thanks well enough, but the other person is not edified. I thank God, I speak in tongues more than you all; however, in the church I desire to speak five words with my mind so that I may instruct others also, rather than ten thousand words in a tongue".
Paul praises God that he speaks in tongues more than all of the Corinthians. He also defines why speaking in tongues is edifiying -- it is praying "in the spirit".
He also says that in church it is more valuable to speak in an understandable language than to speak in tongues.
He doesn't ever say tongues has no value though.
Judgment is also fittingly slated for those who ascribe to satan or the enemy things truly of Holy Spirit.
