1 Corinthians 14:22-24

The Voice

²² So speaking in unknown languages is not a sign to the believing but a miracle to the unbelieving; prophecy, though, is not a sign to the unbelieving but for the believing. ²³ Imagine what would happen if the entire church gathered together speaking in different languages, one foreign to the next. Then people who have never heard of such a thing or unbelieving people walk up on all that’s going on. Would they not think each and every one of you were raving lunatics? ²⁴ But let’s say an outsider or unbeliever walks in on a different scene: all are speaking for God with great power and insight in a language they know. What then? Well, the outsider would come under the conviction of his own sins and be called to accountability by the words of all the prophets.
