Vision is a word /concept that gets a lot of coverage these days both in the Christian world and in the secular world. And it is pretty important. After all without it, people cast off restraint.
It's not always easy to define vision in a visionary way. Which is why I like this quote from Antoine de Sainte-Exupery. It seems to me to capture the essence of vision:
"If you want to build a ship, don't drum up people to collect wood and don't assign them tasks and work, but rather teach them to long for the endless immensity of the sea."
