Jesus told a story about two busy boys. One says he'll obey but doesn't. One doesn't obey but in the end he changes his mind. It's a great story that tells us about God who has the power to change people, and how we must obey Him.
Jesus told stories - great stories - that tell us about who God is and what He is like. In the Stories From Jesus series, the parables are retold and explained for young children.
