Influential Women of the Bible: Esther
The story of Esther is found in the Old Testament book of Esther.
Esther was queen of Persia during the reign of Xerxes I (486–465 BC). She was a woman of the Diaspora (“scattering”), descended from Jews who had been scattered among the nations at the time of the Exile. Her family had not returned to the land of Judah, as some Jews had, but had chosen to stay in the land of Persia, like many others.
Why did her family stay in Persia when other Jewish exiles returned to rebuild their homeland? I’m sure they had their reasons, but it was God’s purpose that ultimately guided their decision. Esther was an orphan and was raised by her cousin Mordecai. She became queen after King Xerxes became displeased with Queen Vashti for refusing to attend a banquet when commanded to do so (Esther 1:11-12). After Esther’s coronation, she won the king’s confidence by informing him of an assassination plot that had been discovered by her cousin Mordecai (Esther 2:21-23). This later enabled her to rescue her people from a massacre planned by Haman, a high official to the king. Through her wise advice and brave action, Esther exposed Haman, he was executed, and the Jewish people were rescued.
While some of the Jewish people returned to Judah, Esther’s family stayed because God had a specific purpose for Esther to fulfill in Persia. And just as in Esther’s day, today God’s people are “scattered” so to speak. We are in different age groups, ethnicities, speak different languages, and come from various backgrounds. God needs various tools to perform varying tasks in the Kingdom of God. For this reason, the “cookie-cutter Christian” does not exist! But God has placed special gifts, abilities, and callings within each one of us to advance the Kingdom of God!
We are not all called to preach or teach; we don’t all have gifts of healing or miracles. But God has a specific need that can only be fulfilled with what He has placed inside of you. There is a need to serve as foster parent or mentor; a need to minister in a nursing home, detention center, or penal institution; there is a need on that board of directors or that planning committee. Your calling may be as a loving husband, or a nurturing mother. Whatever your gift, whatever your calling, seek to glorify God and serve Him faithfully wherever He has placed you. “God has given each of you a gift from his great variety of spiritual gifts. Use them well to serve one another” (1 Peter 4:10 NLT).
