1Cor.14.22

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.

1Cor.14.22

So where does it get you, all this speaking in tongues no one understands? It doesn't help believers, and it only gives unbelievers something to gawk at. Plain truth-speaking, on the other hand, goes straight to the heart of believers and doesn't get in the way of unbelievers.

1Cor.14.22

Tongues, then, are a sign, not for believers but for unbelievers; prophecy, however, is for believers, not for unbelievers.

1Cor.14.22

Therefore tongues are for a sign, not to those who believe but to unbelievers; but prophesying is not for unbelievers but for those who believe.
