What is a recurrent theme regarding God's expectations in the book of Deuteronomy?

The recurrent theme regarding God's expectations in the book of Deuteronomy is keeping the Law and commandments. Deuteronomy serves as a re-statement of the Law given to the Israelites and emphasizes the importance of obedience to God's commandments. The text calls for the Israelites to remember their covenant with God, outlining the blessings that come with obedience and the consequences of disobedience. This theme reinforces the idea that a faithful relationship with God requires adherence to His laws, which are crucial to maintaining the identity and life of the Israelite community.

The other choices, while they may have elements associated with the broader narrative or context of the Israelites, do not capture the primary expectation that God emphasizes repeatedly throughout Deuteronomy. Warfare, ritual sacrifices, and leadership introductions are parts of the story but are secondary to the foundational call for obedience to God’s commandments. The focus on the Law is central to understanding the covenant relationship that God establishes with His people in this book.
