Deuteronomy study notes

Important Concepts

• Love for God: The covenant’s heart is wholehearted love for the LORD (6:5), Israel’s response to His prior electing love, expressed in obedience. Jesus names it the greatest commandment.
• The Oneness and Uniqueness of God: “The LORD is one,” and “there is no other” (4:39; 6:4); this grounds Israel’s exclusive worship and the relentless rejection of idolatry.
• Remembering and Forgetting: Israel must remember God’s mighty acts and their own redemption, and guard against forgetting Him in prosperity; memory sustains faith, forgetting breeds apostasy.
• Grace and Election: Israel’s standing rests on God’s love and choice, “not because of your righteousness” (9:4-6) and “not because you were more in number” (7:7), but purely as a gift.
• Blessing and Curse: The covenant sets before Israel life and death; obedience brings blessing, rebellion brings curse and exile. Moses urges them to “choose life” (30:19).
• The Word Near and the Heart Transformed: The problem of a heart unable to obey is met by the promise that God will circumcise the heart (30:6) and that His word is near, pointing to the new covenant.
• A Prophet Like Moses: Moses looks beyond himself to a coming Prophet to whom Israel must listen (18:15), fulfilled in Christ, the Prophet, Priest, and King greater than Moses.

Practical Application

Deuteronomy speaks directly to the life of faith wherever God’s people enjoy His blessings. Its most urgent warning is against the forgetfulness that comes with comfort: when we are full, secure, and successful, we are most tempted to forget the God who gave it all and to trust our own strength. The remedy Moses presses is deliberate remembering — rehearsing God’s mighty acts, teaching them to our children, and receiving every good thing as a gift from His hand. The call to love God “with all your heart and with all your soul and with all your might” reminds us that God desires not mere outward compliance but the wholehearted devotion of the whole person, a love that shapes how we handle money, treat the vulnerable, pursue justice, and order our homes.

Deuteronomy also exposes the deepest human problem and points to its only cure. Moses tells Israel plainly that they do not yet have “a heart to understand,” and that even the best law, leadership, and covenant ceremonies cannot make them faithful. The book thus drives us to the promise of a circumcised heart and a word made near — a promise fulfilled in Christ, who by His Spirit writes God’s law within and enables the love that the law commands. To read Deuteronomy as a Christian is to hear its call to love and obey God, to feel the weight of our inability, and to flee to the One who bore the covenant curse for us and gives us new hearts, so that we can at last “choose life” by holding fast to Him.

Questions for reflection

1. Deuteronomy warns repeatedly against forgetting God in prosperity. Where are you most tempted to forget the Lord, and how can deliberate remembering guard your heart?
2. The book calls for love of God with the whole self, yet admits Israel lacks the heart to obey. How does this drive you to Christ and the new covenant promise of a transformed heart?
3. Moses sets before Israel life and death and urges them to “choose life.” What does choosing life by loving and holding fast to God look like in your daily decisions?
