The big dream that animates the Book of Isaiah is the dream of a future time of perfect peace—basically the exact opposite of what's been going on throughout the course of the book, what with all its examples of annihilation and total war. The wolf and the lamb are able snuggle together, hang out, watch Friends re-runs—whatever. This is also tied up with Messianic dreams, and for Christians, the redemptive mission of Jesus, who they usually identify with Isaiah's suffering servant.
