Coming of the Holy Spirit Acts 2
2 When the Day of Pentecost had fully come, they were all with one accord in one place. 2 And suddenly there came a sound from heaven, as of a rushing mighty wind, and it filled the whole house where they were sitting. 3 Then there appeared to them divided tongues, as of fire, and one sat upon each of them. 4 And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit gave them utterance.
The Crowd’s Response
5 And there were dwelling in Jerusalem Jews, devout men, from every nation under heaven. 6 And when this sound occurred, the multitude came together, and were confused, because everyone heard them speak in his own language. 7 Then they were all amazed and marveled, saying to one another, “Look, are not all these who speak Galileans? 8 And how is it that we hear, each in our own language in which we were born? 9 Parthians and Medes and Elamites, those dwelling in Mesopotamia, Judea and Cappadocia, Pontus and Asia, 10 Phrygia and Pamphylia, Egypt and the parts of Libya adjoining Cyrene, visitors from Rome, both Jews and proselytes, 11 Cretans and Arabs—we hear them speaking in our own tongues the wonderful works of God.” 12 So they were all amazed and perplexed, saying to one another, “Whatever could this mean?”
13 Others mocking said, “They are full of new wine.”
It is very clear here that the tongues in verse 4 are languages from different parts of the known world at that time. "we hear them speaking in our own tongues"
Peter’s Sermon
14 But Peter, standing up with the eleven, raised his voice and said to them, “Men of Judea and all who dwell in Jerusalem, let this be known to you, and heed my words. 15 For these are not drunk, as you suppose, since it is only the third hour of the day. 16 But this is what was spoken by the prophet Joel:
17 ‘And it shall come to pass in the last days, says God,
That I will pour out of My Spirit on all flesh;
Your sons and your daughters shall prophesy,
Your young men shall see visions,
Your old men shall dream dreams.
18 And on My menservants and on My maidservants
I will pour out My Spirit in those days;
And they shall prophesy.
19 I will show wonders in heaven above
And signs in the earth beneath:
Blood and fire and vapor of smoke.
20 The sun shall be turned into darkness,
And the moon into blood,
Before the coming of the great and awesome day of the Lord.
21 And it shall come to pass
That whoever calls on the name of the Lord
Shall be saved.’
So, Peter is saying that Joel spoke of this type of manifestation of the Spirit. What a great gift from the Holy Spirit, the ability to spread the word of God to people in their native language. Pentecost was not like anything we see in charasamatic churches. Maybe I've missed it but I've never seen a body of belivers filled with the Spirit start talking in other languages. I have seen them speak a utterance that cannot be understood. The very thing Paul rebuked. When Joel in verse 18 says that God will pour out his Spirit and they will prophesy I understand that to say " the Holy Spirit will give them the ability to preach"

I believe Christians confuse, intermix, the message of tongues in Pauls epistles. It's not always talking about a prayer language. I do believe their is a prayer language for believers available today for those who seek it. The scriptures make it clear that our prayer language is TO GOD not from God.
1 Corinithians 14:2
For he who speaks in a tongue does not speak to men but to God, for no one understands him; however, in the spirit he speaks mysteries.
The Holy Spirit does not have limitations. The gifts of the Spirit are available today. I believe that when a person speaks an unknown utterance and someone else in the Church follows that with a message we should consider that it may not be an interpetation of the unknown utterance just heard but prophesy, the gift of communicating reveled truth as Joel mentions. Theologians have been trying to parse Tongues Unknown from Tongues Language within the scriptures for decades. Pentecost is clearly talking about language. The scriptures tell us that point blank.
