Act 2:1 When the Day of Pentecost had fully come, they were all with one accord in one place.
Act 2:2 And suddenly there came a sound from heaven, as of a rushing mighty wind, and it filled the whole house where they were sitting.
Act 2:3 Then there appeared to them divided tongues, as of fire, and one sat upon each of them.
Act 2:4 And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit gave them utterance.
Act 2:5 And there were dwelling in Jerusalem Jews, devout men, from every nation under heaven.
Act 2:6 And when this sound occurred, the multitude came together, and were confused, because everyone heard them speak in his own language.
Act 2:7 Then they were all amazed and marvelled, saying to one another, "Look, are not all these who speak Galileans?
Act 2:8 "And how is it that we hear, each in our own language in which we were born?
As you can clearly see here - the gift given from the spirit of talking in tongues is in fact the ability to understand and talk in many tongues (languages) of different cultures and lands as see here at Pentecost..
Please read chapter 12 of the book Truth matters by Prof Walter Veith for a clearer understanding about this "other" spirit that is being seen in the churches of today.
Here is the link to the book online at google books.

please read this and understand that what you are seeing in the churches of today is not from God!
I am not saying that the Holy Spirit does not perform miracles and does not touch each of us, but be very careful with what you are dealing with as God clearly warns us that what we "feel" may not be from him if it "feels" good.
Feelings can deceive many as well, one of satans many weapons.
