Jesus' love and grace shines in the story of the adulterous woman. When others thought they had her caught and tried putting Jesus between a rock and a hard place (get it?..), Jesus proved them wrong and showed her what no one else would. He showed her what he gives us each day, love. This episode is about evaluating ourselves and how we should be more like Jesus in our daily lives. Sometimes, it not what we always want to hear but it's the thing we need at the right time.
