The Foundation of God's Commandments

Introduction

When you open your Bible to the book of Deuteronomy, you find Moses gathering all Israel before they enter the Promised Land. These are not the same faces as at Sinai: the previous generation has been buried in the wilderness. Moses is speaking to the sons and daughters. He repeats the Law to them, not as a new Law, but as a solemn reminder: here are the statutes and the ordinances your God has given you, listen to them, learn them, put them into practice.

Chapters 5 and 6 are without doubt the two most important chapters of Deuteronomy. They lay the foundation for everything else. Before even speaking of specific laws, Moses goes back to the source: what is the ground on which all of God's commandments rest? The answer fits in one sentence: it is your relationship with him.

You will see in this study that the God who calls you to obey is first the God who wants to be loved. He does not ask for a religious performance. He asks for a heart that turns toward him, that loves him, that listens to him, that remembers. Everything else, your relationships with others, the way you live, flows from that source.

Outline

1. Listen, learn, put into practice (Deuteronomy 5:1)

The first verse sets the tone. Moses summons the whole community of Israel and says: "Hear, O Israel, the statutes and the rules that I speak in your hearing today, and you shall learn them and be careful to do them" (Deuteronomy 5:1). Notice the three verbs: listen, learn, practice. They are three levels of a single movement.

God's word is not first a body of knowledge to file away in a drawer. It is a call. Listening means making yourself available. Learning means understanding what this word means for you, how it applies to your everyday life. Putting it into practice is the stage where everything is decided: without it, God's Law, his ordinances, his statutes have no bearing on your life.

Jesus says the same thing at the end of the Gospel of Matthew, when he sends out his disciples: "Teach them to observe all that I have commanded you" (Matthew 28:20). It does not say "teach them to know," it says "teach them to observe." To live it out. It is the same movement that runs through the whole Bible.

2. The ten commandments: two tables, two foundations (Deuteronomy 5:6-21)

Moses then recalls the ten words God had given at Sinai. These ten commandments naturally divide into two groups.

The first four concern your relationship with God. One God alone. No idols. Do not take his name in vain. Rest on the Sabbath day. When you fail in these four, the Bible calls it ungodliness. Godliness means recognizing God as God, fearing him, obeying him. Ungodliness is refusing that. And ungodliness is the root of all sin: because I do not fear God, because I do not honor him, because I do not obey him, everything else starts to go wrong.

The next six concern your relationships with others. Honor your father and your mother. You shall not murder. You shall not commit adultery. You shall not steal. You shall not bear false witness. You shall not covet. When you fail in these, the Bible calls it injustice. That is, you fall short of God's standard.

Here is what you need to understand: these two groups are not independent. The second rests on the first. Without a living relationship with God, you will not be able to keep the six commandments that bind you to others. You can try, you can rearrange the content to suit yourself, but you will not hold up.

3. Modern idolatry: to covet is to worship

"You shall not make for yourself a carved image" (Deuteronomy 5:8). Today, as a Christian, you are probably not going to carve a statue to bow down before it. But the New Testament broadens the definition. Paul writes in Colossians 3:5: "Put to death therefore what is earthly in you: sexual immorality, impurity, passion, evil desire, and covetousness, which is idolatry."

Covetousness is idolatry. When you want something so much that it takes God's place in your heart, that thing becomes your god. Your family, your work, your money, your hobby, your phone, a show, a project: none of these is bad in itself. None of it. But if you can no longer set it aside to turn toward God, if it keeps you from seeking first the kingdom of God and his righteousness (Matthew 6:33), then it has become an idol.

The test is not how many hours you spend on it. The test is what keeps you from going to God when you want to go to him. You open your Bible to read, and suddenly a thought pulls you away: "Oh, there's that game, that news story, that technique I want to try." It is not the mere existence of these things that is the problem. The problem is that you can no longer set them down. What you cannot set down, you worship.

4. The Sabbath: resting in grace, not in restlessness

"Observe the Sabbath day, to keep it holy" (Deuteronomy 5:12). The Sabbath is not a box to check: "I was at church Sunday, that's covered." Nor is it a day where you do nothing and just drift through the hours.

The Sabbath is the moment when you set down your efforts, your work, your projects, in order to meditate on who God is. To remember what he has done. To let yourself be touched by his love, his mercy, his grace. If you take Sunday as your Sabbath, do not live it simply as the day you do not work. Live it as the day you truly taste the living relationship God has offered you in Jesus Christ.

Taking time together, praying with others, sharing life, all of that is good. But when it turns into "I absolutely must do this, I must do that," you fall back into restlessness. What you are truly called to do on that day is stop, set your worries aside, turn your heart toward God, and let Jesus Christ meet you at the dry place where you are. The Sabbath is coming to drink from the source.

5. The Shema: God is one, love him with your whole being (Deuteronomy 6:4-5)

We now arrive at the heart of it all: the Shema. "Hear, O Israel: The Lord our God, the Lord is one. You shall love the Lord your God with all your heart and with all your soul and with all your might" (Deuteronomy 6:4-5). This is the confession devout Jews have recited every day for thousands of years.

One detail in Hebrew is worth noting: the word translated "God" is Elohim, which is grammatically plural. And the word translated "one" is echad, which describes a unity made of several parts coming together. It is not yachid (a single, solitary one). It is echad, the unity of a single body. The Old Testament text already hints at what the New Testament will fully reveal: the Father, the Son, and the Holy Spirit, three persons, one God. The doctrine of the Trinity does not appear as a word in the Old Testament, but the structure of the language is consistent with it.

And here is the call: love that God with all your heart, all your soul, all your might. This is the word agape from the New Testament Greek: a love that pours everything it is into the object of its love.

Notice this well: God is not first someone to be afraid of, someone before whom you would tremble because he is about to strike you. He is the one toward whom you turn your love. If your heart holds only the fear of punishment, then somewhere you do not yet love him the way he calls you to love him. True love for God comes as you begin to know him. And to know him, you must listen to him, learn from him, back to square one from Deuteronomy 5:1.

6. Write these words on your heart (Deuteronomy 6:6-9)

"And these words that I command you today shall be on your heart. You shall teach them diligently to your children, and shall talk of them when you sit in your house, and when you walk by the way, and when you lie down, and when you rise" (Deuteronomy 6:6-7). This is not about muttering a verse on repeat all day long. It is about a heart that never stops remembering.

A written reminder (a cross around your neck, a Bible open on your table) is not a bad thing. But the true reminder is the Holy Spirit writing the word on your heart. When you truly love someone, you do not need a sticky note on the fridge to think of them: that person is there, all the time, in your heart. That is what the Holy Spirit comes to do with God's words.

7. Do not forget God when everything is going well (Deuteronomy 6:10-12)

Moses warns: when you enter the land, into cities you did not build, with houses full of good things you did not fill them with, wells you did not dig, vineyards and olive trees you did not plant, "take care lest you forget the Lord, who brought you out of the land of Egypt, out of the house of slavery" (Deuteronomy 6:12).

This is our great danger. In hardship, we pray fervently, we cry out to God. Then the hardship passes. The answer comes. And we forget. We receive it as if it were normal. A two-second "thank you, Lord," and we move on. Even though, just days earlier, we were pleading for an hour.

Think about this image: if someone wiped out a debt of several million for you, you would not simply say "thanks" and walk away. You would think about it every day. At every meal, every plan, you would tell yourself: "Without that person, where would I be?" How much more so for what Jesus Christ did on the cross to wipe out our debt to God? Do not let routine make you forget.

8. A jealous God, a God who wants your good (Deuteronomy 6:14-15; 5:29)

"You shall not go after other gods" (Deuteronomy 6:14). Why not? Because "the Lord your God in your midst is a jealous God" (Deuteronomy 6:15). God's jealousy is not a whim. Nor is it a threat aimed at destroying you. It aims to protect you from what would destroy you.

When you give your heart to things that are not God, those things can give you nothing back. You are throwing bread into the sea: it dissolves, it does not come back. That is not where true joy, true peace, true hope are born. God's jealousy is his refusal to watch you burn yourself out for something that cannot feed you.

Listen, too, to God's sigh in chapter 5. After hearing Israel promise "we will listen and we will put it into practice," God says to Moses: "Oh that they had such a heart as this always, to fear me and to keep all my commandments, that it might go well with them and with their descendants forever!" (Deuteronomy 5:29). That is the heart of God toward his people. He is not trying to force you; he desires your happiness, your stability, a blessed future for your children.

Key takeaways

• God's word is meant to be lived out. Listen, learn, put into practice: these are three stages of a single movement. Stopping at the first or second stage means missing the point.
• Your relationship with God is the foundation of everything. You will not keep the commandments toward others if your relationship with God is empty. That is the order in which it works.
• Covetousness is idolatry. Today's idols are not carved from stone. They are called television, money, success, screens, sports, shows. Not bad in themselves; bad when they take God's place.
• The Sabbath is letting yourself be given a drink. Not a box to check, not a day of idle drifting. A set-apart time to meditate on God, to let Jesus touch what is dry in you.
• Loving God means knowing him. The Shema does not call for robotic submission, but for a love with your whole being. That love is born as you learn who he is.

Personal application

Take a quiet moment and let these questions sink in:

1. What have I heard from God's word this week without putting it into practice? What concrete step can I take today?
2. Is there something I am coveting right now (an object, recognition, a position, a relationship) to the point that it is stealing ground from God in my heart?
3. How do I actually live my Sabbath? Is it real rest in God, or just a pause before I pick up the race again?
4. Do I love God, or do I mainly serve him out of fear? What is missing in my knowledge of him that would help me love him more?
5. When a prayer was recently answered, how much time did I take to give thanks? Am I in danger of forgetting too quickly?

FAQ

Why does Moses repeat the ten commandments in chapter 5 when they had already been given at Sinai?

Because the generation that received them at Sinai has died in the wilderness. Moses is addressing their children, before they enter the Promised Land. He is not giving a new Law: he is repeating the same Law to those who must now live it out concretely in the land they are about to receive.

How can I know if something has become an idol in my life?

The test suggested here is simple: can you set that thing down in order to turn toward God? If it keeps you from seeking first the kingdom of God, if it grabs your attention just when you want to pray or open your Bible, if you covet it to the point that it fills the space of your heart, then it has taken a place it should not have.

What does it really mean to love God "with all your heart, all your soul, all your might"?

It means putting everything you are into that love, with no part held back for yourself. It is not a performance to be measured in hours or effort. It is a heart that turns toward God with everything it is. And that love grows as you learn who God is, through his word, through prayer, and through the work of the Holy Spirit who writes these things on your heart.
