Then Esther sent this reply to Mordecai: 'Go, gather together all the Jews who are in Susa, and fast for me. Do not eat or drink for three days, night or day. I and my maids will fast as you do. When this is done, I will go to the king, even though it is against the law. And if I perish, I perish.' So Mordecai went away and carried out all of Esther's instructions.
Esther's reply has a wonderful lesson for us today. When faced with this trial and decision, she called for fasting. As we see, this is denial of food and drink to oneself in order to focus on the things of God. It is significant that she asked for three days of fasting in that the number three is associated with the revealing of God's will throughout the Bible.
