Watching a marathon is not the same as running a marathon.  Reading about rock climbing is not the same as actually rock climbing.  Taking a campus tour is not the same as earning a college degree.  There are many experiences that are far more meaningful when we voluntarily put ourselves in the risk and challenge - instead of just observing from the sidelines.  Jesus led His closest followers into a storm so they could experience an amazement that could not be discovered from standing on the shore.
