Epiphany is the celebration of the arrival of the Magi or Wise Men who travelled so far to worship the Christ-Child.  As we see what is means throughout the history of the Bible that God welcomes all kinds of different people into his kingdom, and raises up leaders in foreign nations, we begin to see that we are those "foreigners" that God welcomes into his family through his Son.  We aren't "foreign" to the Kingdom of God because of enthnicity, we are foreigners because of our sin!  But Christ came to be the sacrifice for our sin, and he opens wide the door to his Kingdom in his Grace!
