Arranged as a series of sermons, the book of Deuteronomy represents the final major segment of the biography of Moses. The sermons review events described in earlier books and challenges Israel to faithful living in the future.

The theological significance of Deuteronomy cannot be overestimated. Few books in the Bible proclaim such a relevant word of grace and gospel to the church today. At its heart, Deuteronomy records the covenantal relationship between God and his people. God graciously has chosen Israel as his covenant partner and has demonstrated his covenantal commitment to them. Moses challenges the Israelites to respond by declaring that Yahweh alone is their God and by demonstrating unwavering loyalty and total love for him through obedience.

Daniel Block highlights the unity between the God depicted in Deuteronomy and Jesus Christ. Christians who understand the covenantal character of God and who live under the grace of Christ will resist the temptation to retreat into interior and subjective understandings of the life of faith so common in Western Christianity.
