Our lives are filled with risk, chances that we will be harmed in some way. Each of us employs different methods of lowering that risk and insuring our safety. We weigh the consequences of what we eat, what we do, who we associate with. We balance the excitement and enjoyment of the new and unpredictable with the chance that we might get hurt.
Judaism is one technology for mitigating the risk in our lives. It is a path to safety. It is a way of approaching new people and new experiences with a set of criteria to assess the danger. But it is not simply a way of staying with the old and well-known. We must try the new - create a new song - even the face of risk.
