Advent is a time of waiting. Isaiah 11 gives us a vision of what it is we're waiting for--the kingdom of peace, where true justice is mediated by God's chosen one, where even the animal kingdom is united as the wolf lives side by side with the lamb and the lion eats grass like the ox. Sounds impossible, right? So does the idea of God coming to earth in the form of a little baby. But Christmas just might be the time when the impossible becomes believable and maybe even enters our reality.
