My son Joel is six years old. He is quite an amazing boy, for lots of reasons. One of them is this: he has worked out that the world is unjust; he has learned that poverty exists, and he is not happy about it. He had heard a few things at school and church, but when we watched a short video made by Tearfund, he decided that he couldn't just stand by and let this happen.
It's often good to see things through the eyes of a child.
