The book of Esther reads like a novel as it tells the story of how a beautiful, Jewish orphan girl rises to wield significant power in a pagan king’s court. God would ultimately use her to save the Jews from genocide. A recurring theme in Esther is that God raises up the most unlikely people to fulfill His will. Everything happens for “such a time as this.”
The book of Esther makes it clear that God is in control of history even when rulers make unwise and evil decisions based on sinful motivations. Even the smallest impulses and motivations of men and women gone astray are used in the hands of God to rescue His people. God is always skillfully directing all things. He is after all, not only the God of the rulers of the kings of the earth, He is also the God of the gallows.
