Tongues is nothing more than a language
Below is the "tongues" of the book of Acts, and as you can see there was nothing "unknown" about it!
Acts 2:4
4 And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance. (KJV)
other: Greek word #2087 heteros = other or different:
Tongues: Greek word #1100 glossa = a language (specially, one naturally unacquired)
When they spoke this tongue, everybody understood it, the Scripture lists 18 different languages that understood it AT ONCE! Not like today's so-called tongues where only another possessed person can think that he understands it. The Pentecostal Day (Acts ch. 2) tongues were heard and understood by all languages:
Acts 2:4-11
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. (KJV)
What is happening in the churches today is so far removed from the Scriptures that one could only suspect demonic influences. Stop babbling, it is not of God!
Also, let us clear-up one more obstacle in this matter. The "Tongue Talker" teachers point to the below Scripture as a justification for their own so-called Tongue Talking in their churches. The Scripture below follows right after the above verse, so that you know that it is the exact same subject being spoken of:
Acts 2:12-16
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.
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; (KJV)
What the Tongues preachers/teachers will tell you is that some men called the speakers "drunk" because they could not understand what they were saying. Based on this, the Tongue teachers assert that when they speak in their babble, which people can't understand, it is the same as in the above Acts Scripture, because, as they arrantly suppose, nobody could understand it.
Not so! First of all we just read that many DID understand, in (all) their own (different) languages even; but that some could not understand. So confused were those who could not understand that they accused the speakers of being so drunk that they couldn't even form words recognizable to the human ear. Paul assures them that the men are not at all drunk.
So in our above Scripture in verse 12 we saw that many did hear, but in verse 13 we saw that some did not hear:
Acts 2:12-13
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.
Who then are these, whom could not hear (could not understand the speech)? They were unbelievers. Unbelievers cannot hear with understanding the Holy Spirit, because the Holy Spirit, which interprets all things (for the Christian ONLY), is not present in the unbeliever. That is why these certain men, those who were mocking, could not understand what the Holy Spirit was saying through the Inspired speakers. Jesus told us of these in another place:
John 8:43
43 Why do ye not understand my speech? even because ye cannot hear my word. (KJV)
To understand Jesus is to understand the Holy Spirit, for they are One with the Father (1st John 5:7). Jesus said that His sheep hear His voice:
John 10:26-31
26 But ye believe not, because ye are not of my sheep, as I said unto you.
27 My sheep hear my voice, and I know them, and they follow me:
28 And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.
29 My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
30 I and my Father are one.
31 Then the Jews took up stones again to stone him. (KJV)
So who were those who could not hear the Holy Spirit? It was those same who would instigate the crucifixion of Jesus Christ:
John 8:42-51
42 Jesus said unto them, If God were your Father, ye would love me: for I proceeded forth and came from God; neither came I of myself, but he sent me.
43 Why do ye not understand my speech? even because ye cannot hear my word.
44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
45 And because I tell you the truth, ye believe me not. (KJV)
Well the spirit of Pharisee'ism is alive and well in many of the compromised & spiritually corrupted Judeo-Christian churches. There is really no such thing as Judeo-Christian, it is new wine in an old (actually another) wineskin that shall burst. It is satan's dilution of the Christian faith.

The next time true tounges as in Acts will be spoken is when the elect are delivered up to satan
Mark 13:9, 10 "But take heed to yourselves: for they shall deliver you up to councils; and in the synagogues ye shall be beaten: and ye shall be brought before rulers and kings for My sake, for a testimony against them." [9] "And the gospel must first be published among all nations." [10]
Mark 13:11 "But when they shall lead you, and deliver you up, take no thought beforehand what ye shall speak, neither do ye premeditate: but whatsoever shall be given you in that hour, that speak ye: for it is not ye that speak, but the Holy Ghost [Spirit]."
