Second, a good word of caution from John Piper (found here):
I think we should spend most of our creative energies on constructing in our minds and in our hearts and in our families great and beautiful and glorious alternative visions of reality than the ones we are being offered by the world. If we give most of our time to bemoaning and criticizing the world for acting like the world, our vision of God and his glorious future for his people will become smaller and smaller, and that could be a greater tragedy than the one we are living in.
