What is the main theme of the Book of Judges?

The main theme of the Book of Judges is indeed the need for a godly king. This theme emerges through a cycle of events where Israel experiences a pattern of sin, oppression, crying out to God for deliverance, and being rescued by judges raised by God. The recurrent refrain that "everyone did what was right in his own eyes" emphasizes the consequences of not having a centralized leadership or a divinely appointed king. It highlights the moral and spiritual decline of Israel during this time, illustrating a longing for a ruler who would lead them in faithfulness to God. The narratives in Judges set the context for the eventual establishment of kingship in Israel, pointing towards the necessity of a godly leader to guide the people.

In contrast, the other themes mentioned do not accurately reflect the focus of the Book of Judges. The achievements of King David are found in the books of Samuel, while the creation narratives are central to Genesis. The exile of Israel is primarily discussed in the context of the books of Kings and the prophetic writings. Each of these reflects significant moments in Israel's history, but they do not encapsulate the prevailing message of Judges regarding the need for a divinely appointed king.
