Every story must have a hero as well as a villain. In the story of Purim, Esther certainly has a leading role, but I suggest Mordecai is the real hero. It was he who raised Esther to be a God fearer. It was Mordecai who refused to compromise his faith in the God of Israel. And it was Mordecai who gave Esther the challenge which made the difference and resulted in the deliverance of Israel.
