What Language Will We Speak in Heaven?

There are several questions that I have about heaven. One of them is, what language will we speak in heaven. I think that is a far more relevant question than asking God about UFOs or who shot JFK. If we are going to be in heaven and in community with people from all different countries and generations it seems like it is going to be pretty important to communicate with one another. Now, what I am about to say is pure conjecture but see what you think and let me know what ideas you have about it.

In the Bible God reveals himself to people in their native language. He speaks to Moses on Sinai in Hebrew. God, Jesus, and the angels reveal themselves to John in the book of revelation presumably in Greek or Aramaic. Obviously, God can use whatever language he wants because He knows it all anyway. But what about our communication with each other in heaven?

1. 1 Corinthians 13 talks about the tongues of men and of angels so there seems to be a possiblity of other languages that could be used in heaven that we are not even aware of yet.
2. In Acts 2, the Holy Spirit comes upon the apostles and they begin to speak in tongues to the crowd of Jews from all over the world. Acts 2:6-8 says, "When they heard this sound, a crowd came together in bewilderment, because each one heard them speaking in his own language. Utterly amazed, they asked: "Are not all these men who are speaking Galileans? Then how is it that each of us hears them in his own native language?"God grants the apostles the ability to speak other languages. Presumably when Peter alone addressed the crowd he spoke in Greek so that everyone present could understand him.
3. There is no scriptural example of this but I often wonder if when we get to heaven we will all speak our own language and hear each other in our own language. So I speak to Paul in English and he hears Greek. He replies in Greek and I hear his Greek response in English. I am probably going way out on a limb here but I think it is kind of fun to think about how this will work. That would allow us the full range of expression of our native language.
   
4. We could all know one language - Hebrew, Greek, etc. This would take away that old scholarly joke about those who know Greek & Hebrew will be the only ones who will be able to have conversations in heaven with those from the Bible.
   
5. We could all understand all languages present.

God has used language in a miraculous way in the past and it makes me wonder if there is something coming down the pipe that will blow our minds. Maybe there is an outside the box explanation that there will be something new that blows away everything that we have ever experienced here. We may not know for sure but certainly one day we will. Maybe we will sit around and talk about these comments and see who was closest ;)

Any way you cut it, it is miraculous. Whatever way God works this out I will certainly not take issue with. What ideas do you have?
