Let's look at Haman. This guy hates Mordecai not just because he's a Jew, but because Mordecai will not bow down to him. So Haman talks the king into a game plan. "If you follow my rules, I will pour money into your treasury."
Let's look at Haman. This guy hates Mordecai not just because he's a Jew, but because Mordecai will not bow down to him. So Haman talks the king into a game plan. "If you follow my rules, I will pour money into your treasury. All I ask is that you give me the right to rid the land of all these Jews." And so King Ahasuerus, believing Haman and ignoring the brutal genocide he is plotting, passes it off with a wave of his hand, "Go ahead, do whatever you need to do."
When Mordecai gets word of what Haman is planning, he makes a crucial but dangerous decision. He must tell his adopted daughter, Esther; she must know about Haman's evil plan. Because, you see, by now Esther had become queen, but nobody knew she was a Jew. When she was chosen as the king's consort, Mordecai had advised her not to tell anybody about her ethnic origins. Obediently, she hadn't (Esther 2:10).
Mordecai entertained no doubt that the Jews would survive this holocaust. He was convinced that God would not let His people be wiped from the face of the earth. He and Esther might be killed, but ultimately someone would deliver the Jews. However, what if God's plan was already in process? What if the means to that deliverance had already been put in place by the hand of God? What if it included Esther's getting involved? She was, after all, the queen.
"Esther, listen!" says Mordecai. "God's hand was on my getting the message from Haman that the Jews will be killed. And God's hand was on your being appointed queen. Perhaps you were put into this position just for this altogether unique hour in our history. Don't be silent. This is your greatest hour. Speak! Plead with the king. Stop this plot against our people!"
I've heard some people claim that they can't believe in the sovereignty of God because doing so makes you passive. Frankly, I don't see it. Not if it stays balanced and biblically oriented. If anything, the sovereignty of God makes me active. It drives me before Him as I plead, "Lord, involve me in the process, if it pleases You. Activate me in Your action plan. I'm available. Speak through me. Use me."
