Let me share with you a couple of quotations that point out the importance of this book.
"Deuteronomy is one of the greatest books of the Old Testament. Its significance on the domestic and personal religion of all ages has not been surpassed by any other book in the Bible. It is quoted over eighty times in the New Testament . . . in all but six books . . . and thus it belongs to a small group of four Old Testaments books (Genesis, Deuteronomy, Psalms, and Isaiah) to which the early Christians made frequent reference."10
"The book of Deuteronomy is the most important book in the Old Testament from the standpoint of God's revelation to man."11
Deuteronomy is not just a recapitulation of things previously revealed in Exodus, Leviticus, and Numbers. It is a selective digest of matters most important to the average Israelite in his or her relationship with God. Moses spoke as an aged father to his children. These are the parting words of the man who communed with God face to face. His words in Deuteronomy spring from a personal and intimate knowledge of God that had matured over 120 years.
One of the striking features of this book is the frequent references to love that recur throughout it. God's love for the patriarchs and later the whole nation of Israel is obvious in the previous four books of the Pentateuch, but Moses never articulated it directly. In Deuteronomy for the first time Moses revealed that it was God's love for Israel that motivated Him to deal with the Israelites as He had.
One of the great revelations of this book is the motivation of God. God's love for people moved Him to bless. Moses referred to God's love for people as the motivation of His government in three of the book's major sections.
It constitutes the climax of Moses' first address to the people (1:6-4:40) in which he reviewed God's faithfulness to the Israelites. It was because God loved them that He had treated them as He had (4:32-40, esp. v. 37).
In the second address, which is an exposition of the Mosaic Law (chs. 5-26), Moses explained that God's love motivated His laws (7:7-11; 10:12-22, esp. v. 15; 15:16; 23:5; et al.).
In the conclusion of the book, which records Moses' blessing of the nation (ch. 33), he again reminded the people of God's love for them (33:2-5, esp. v. 3a).
Not only does Deuteronomy reveal that God's love is what motivates Him to govern His people as He does. It also emphasizes that man's love for God should be what motivates us to obey God (cf. 1 John 4:19). This theme too recurs throughout the book.
In Moses' review of the law (chs. 5-26) he called on the Israelites to love God (5:9-10; 6:4-5; 7:9; 10:12-13; 11:1, 13-14, 22-23; 13:1-13, esp. vv. 1-3; 19:8-9). The Israelites' obedience to God's laws expressed their love for God. Love is the most proper and adequate motivation for obedience and service.
We hear this theme again in Moses' third address (chs. 29-30) in which Moses exhorted the new generation of Israelites to obey their covenant, the Mosaic Covenant (30:6, 15-20).
The message of the book then is that God's love for man is the motivation of His government, and man's love for God should be the motivation of his obedience.
This emphasis on love appears even more striking in comparison with other ancient Near Eastern suzerain-vassal treaties. The ancient Near Eastern kings delineated clearly the rights of the ruler and the responsibilities of the subjects in these documents. However the motivation was self-interest, the opposite of love. Concern for others was present, but self-interest predominated.
Since Moses set Deuteronomy in the form of a suzerain-vassal treaty we can learn much about how he viewed Israel's relationship to God.
To quote Thompson again, "Both the literary shape of Deuteronomy and its underlying central concept provide an important clue to the basic theology of the book. Yahweh, the God of Israel, appears in a strong covenantal setting. He is the great King, the Lord of the covenant. From this central concept Israel's finest theological ideas derived."12
These "ideas"include the fact that Yahweh is the Lord of the covenant and the God of history.
Obedience to God and His covenant brings blessing whereas disobedience incurs curses. Israel was the people of the covenant.
The people were to worship their Lord by loving Him with their hearts and remembering Him and His acts with their minds.
There are perhaps four basic implications of this revelation and these correspond to four major sections of the book.
1. It is important to remember God's past faithfulness to appreciate His love (1:6-4:40). God commanded the Israelites to remember. Forgetfulness was a sin that would lead them to ingratitude and ultimately to apostasy. To forget was to rebel against God. Remembering the past would remind the people of God's love and rekindle their love for Him. Love as well as trust rests on confidence. We can love God only when we have confidence in Him.
2. God's laws are an expression of His love (chs. 5-26). Because man is a sinner he needs divine laws. God's provision of these laws is an expression of His love for mankind. The specific laws in the Mosaic Code expressed God's love because God intended them to result in Israel's blessing and welfare. Often we think laws are undesirable because they curb our freedom. However, God curbs our freedom to keep us from evil, not to keep us from good.
3. Only love for God will adequately motivate a person to be obedient to God's laws (chs. 27-28). These laws in Israel were so severe that the only motive strong enough to produce consistent obedience was love. Moses urged the Israelites to cultivate their love for God as they prepared to renew the covenant. Self-confidence had failed their fathers, and it would fail them too. Obedience to God can be a joyful or a bitter experience depending on one's motivation.
When we know God we love Him, and when we love God we will want to obey Him.
4. Obedience to God demonstrates love for Him (chs. 29-30). While it is possible to obey God with lesser motives, it is impossible to be consistently obedient without love for God. Consistent obedience is not the same as sinless perfection. The measure of one's love for God is the measure of his or her obedience to the revealed will of God (1 John 5:3). The degree of our commitment to do the will of God is the true measure of our love for God. The real test of our love for God is what we do more than how we feel.
