God will use you, no matter how broken you are, if you are obedient. This is the lesson we can learn from the book of Esther.
Esther started as a simple Jewish girl. But God asked her to be obedient, and she ended up risking her life to go before the king and make a request that her people be saved. She went with the knowledge that she would most likely be killed. But Esther had faith and was obedient.
