Have you ever been in a congregation where you knew several of the people who were doing it? (I imagine all those people in the Bible who started speaking in tongues right after they were baptized probably freaked out a few strangers who might have been watching...… How odd of God to deliberately discourage people that way.)
But the some understood what they were saying and were amazed because they were native Galileans.
Acts 2:4 And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance. 5 And there were dwelling at Jerusalem Jews, devout men, out of every nation under heaven. 6 Now when this was noised abroad, the multitude came together, and were confounded, because that every man heard them speak in his own language. 7 And they were all amazed and marvelled, saying one to another, Behold, are not all these which speak Galilaeans? 8 And how hear we every man in our own tongue, wherein we were born? 9 Parthians, and Medes, and Elamites, and the dwellers in Mesopotamia, and in Judaea, and Cappadocia, in Pontus, and Asia, 10 Phrygia, and Pamphylia, in Egypt, and in the parts of Libya about Cyrene, and strangers of Rome, Jews and proselytes, 11 Cretes and Arabians, we do hear them speak in our tongues the wonderful works of God. 12 And they were all amazed, and were in doubt, saying one to another, What meaneth this? 13 Others mocking said, These men are full of new wine.
Now does anyone during those modern events stand and preach to everyone like Peter did below? Or was it all about laughter & confusion?
Acts 2:14 But Peter, standing up with the eleven, lifted up his voice, and said unto them, Ye men of Judaea, and all ye that dwell at Jerusalem, be this known unto you, and hearken to my words: 15 For these are not drunken, as ye suppose, seeing it is but the third hour of the day. 16 But this is that which was spoken by the prophet Joel; 17 And it shall come to pass in the last days, saith God, I will pour out of my Spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams: 18 And on my servants and on my handmaidens I will pour out in those days of my Spirit; and they shall prophesy:
No falling down or loss of self control here. But in these movements, no edification, but the phenomenon lasts as long as it does, then they trail off and go home.
It just comes off as all about that phenomenon in taking the spotlight off of Jesus Christ in worship and that is how it ends.
