The book of Esther's inclusion in the inspired scripture was controversial due to the lack of God's name in the text, and it's understandable as it was written at a time when the people of God were scattered from their homeland and felt abandoned by God. However, what we find when studying this book couldn't be further from the truth.
Even when Israel felt far from God, He was always constant in His protection and provision of His people.
