“And who knows whether it is for a time like this that you have attained to your royal status?”
~Esther 4:14

Queen Esther’s adoptive father, Mordecai, asked her to risk her life by presenting the plight of her people before the king without her first being summoned (Es. 4:7,8).
Haman, a prince who had been appointed at the top of the king’s court, had conspired to annihilate all the Jews in the Persian kingdom, financing the extermination himself (Es. 3:8,9).
King Ahasuerus (Xerxes I), who badly needed the money offered by Haman to finance his war against the Greeks, did not know his favorite wife and only queen would be a direct victim of the genocide.
He had a strict policy regarding being approached at his throne; not even the queen would be exempt from punishment, and she had not been called for in 30 days (Es. 4:11).
When the king originally decided to select a new virgin as queen, over one year earlier, the list of confidants the king was closest to does not even mention Haman (Es. 1:14).
Still, Jehovah insured, through the loving care of Mordecai, that Esther came to the throne and eventually saved her people from their death sentence (Es. 2:7, 19, 20; 7:3-6).
God is always two steps ahead of whatever evil his enemies are planning.
It is impossible to thwart God’s purpose.
