Someone wise (G.K. Chesterton?) once said that the world does not lack for wonders, only for a sense of wonder. In the same way, Isaiah is suggesting that the world does not lack for new possibilities, but it lacks for a sense of vision to see those possibilities.
If your future seems closed and predictable, if you get up each morning thinking that today is going to be just as dull and disappointing and humiliating as the last, then maybe the problem is not with the day but with our ability to see the new things that God has begun.
