At first she doesn't get it. But she will. So some people today at first don't get missions, because they don't see the world the way Jesus does. They can see a temple made of bricks and a birth with blood and pain and water from a well. But they don't get a man who is a temple, and a birth by the Spirit, and water that satisfies for ever.
Missions assumes a whole new way of looking at the world.
One more example before we look at our text. In chapter six Jesus miraculously feeds over 5,000 people from five barley loaves and two fish. But they didn't get it. They were stuck in their limited worldview. You will never have a heart for missions if you don't see the world the way Jesus sees it.
