Here's an instructive story. In John chapter 9 we come upon a man the world thought insignificant, a man born blind. Jesus and his disciples, we are told, happened upon this man. The bad things that happen in life cannot always be directly traced to something you or your parents did. Life isn't always fair.
Bad things happen in a sinful world.
You see, the man's blindness was a place, an occasion, where God could show what He could do. Then Jesus immediately adds a sense of urgency. Showing what God can do in common, everyday lives is an imperative laid on Him by the Father. And feeling the urgency to touch a common man's life, Jesus acts. The blind man washed it off and returned.
