"Yet we hear them speaking in our own tongues of the mighty acts of God." (Acts 2:11)
In the world of science fiction & fantasy (you know who you are!), there is a phrase sometimes used in gatherings or groups celebrating various otherwise nerdy things - 'this is my tribe'.
Of course, feeling the outsider isn't limited to things geeky. It's possible to feel isolated in a crowded room or alone even though having a surplus of 'friends' on the various social networks.
What can transcend differences? The easiest common denominator is language; speaking the same language brings an immediate closeness. Not just in the words we use, but the shared cultural experiences that form our language.
But we don't all have the faculty for languages and there is a limit to the abilities of even the most knowledgeable linguist.
Notice the miracle of our celebration of Pentecost. Though the miraculous work of the Holy Spirit was to enable communication across language barriers, the common language is the language of Gods mighty acts. The shared experiences across cultures and tongues is Gods work among them.
