Esther is one of the most complicated stories in all of Scripture. It has been disparaged, praised, ignored, and sanitized.
A straightforward reading of this book brings up a lot of moral questions, including "Where is God and why isn't He mentioned?" As we work through this book, we'll discover God's fingerprints are all over this story as He works behind the scenes to accomplish His will.
In the end, the book reminds us that nothing can stop God from keeping His promises. It's a glorious truth repeated from Genesis all the way to Revelation. And here in Esther, we see it play out despite the participants including unwitting world leaders and unfaithful people.
