All of Christianity has been deeply influenced by Deuteronomy (the second giving of the law); this book’s scope and force is absolutely breathtaking when considered from the standpoint of theology. Christ quotes Deuteronomy 6:5 in summarizing “all the law and the prophets.” And when Jesus faces Satan in the wilderness, he quotes exclusively from Deuteronomy. Other Old Testament texts, like Job and Ecclesiastes, wrestle with the blessing/curse theology found in the later chapters of Deuteronomy.
Overall, however, Deuteronomy’s overarching theme is that of covenant—God’s unwavering promise of dedication to His people. In the New Testament, Christ will be the fullest expression of this covenant: proper understanding of this theme will open your eyes to the full beauty of Christ’s sacrifice. This volume seeks to help you understand God’s covenant interaction as clearly as possible, and what it means to “Love the Lord your God with all your heart, all your soul, and all your might.”
Peter Craigie, approaching this from a conservative position, elaborates on and explains this main theme of covenant and thoroughly expounds Deuteronomy as a whole in the New International Commentary: The Book of Deuteronomy.
