رِسَالَةُ بُولُسَ ٱلرَّسُولِ ٱلأُولَى إِلَى أَهْلِ كُورِنْثُوسَ 14:22

إِذًا ٱلْأَلْسِنَةُ آيَةٌ، لَا لِلْمُؤْمِنِينَ، بَلْ لِغَيْرِ ٱلْمُؤْمِنِينَ. أَمَّا ٱلنُّبُوَّةُ فَلَيْسَتْ لِغَيْرِ ٱلْمُؤْمِنِينَ، بَلْ لِلْمُؤْمِنِينَ.

Wherefore tongues are for a sign, not to them that believe, but to them that believe not: but prophesying serveth not for them that believe not, but for them which believe.
