God likes to use ordinary, everyday people to accomplish great things for His purposes! The bible is full of them, Abraham, Moses, Noah, Mary, the disciples, the list goes on and on. Some of them such as Samuel, King Josiah and David were children. I thought though about David automatically, because in his story, he is overlooked by his own father. Can you image? It's bad enough for everyone else to view you as insignificant but your own Dad? That's rough!
