“Go, gather together all the Jews that are present in Shushan, and fast ye for me, and neither eat nor drink three days, night or day: I also and my maidens will fast likewise; and so will I go in unto the king, which is not according to the law: and if I perish, I perish.” Esther 4:16

It wasn’t Esther’s beauty or position that influenced the king to save the Jews. It was her fasting that appealed to God, who then influenced the heart of the king to save the Jews.
