Tongues of Fire

So I went to church today and my pastor gave a sermon that I had to think about. Today is the pentecost. That was a time when there were tons of people from all over the world who came together to trade. They all spoke different languages. Then, all of a sudden, God sent tongues of fire from the sky so that all the people could talk in the same exact language in the same exact way. I was thinkng, How much easier would it be to go to different countries if all the people spoke the same language? Pretty awesome! But think about it. Wouldn't the world be boring?
