Written in Stone, Written on Hearts

Exodus 19:3-6; 20:1-17; Jeremiah 31:31-34

The Sinai covenant, the law, and the new covenant promise

Main Point

At Sinai, God did not give Israel a list of rules — He gave them a relationship. 'I am the LORD your God who brought you out of Egypt' comes before the commandments. The law was always meant to be the shape of a loved life, not the terms of a contract. But Israel could not keep it in their own strength. So God promised a new covenant — the same law, but written on the heart by the Spirit.

Application Ideas

Do you experience God's law as burden or as gift? The Ten Commandments were given to a people God had already rescued. They are not the way to earn God's love — they are the shape of a life that has already received it. This week, read the Ten Commandments through the lens of grace rather than obligation.

Discussion Questions

Why does God introduce the Ten Commandments by reminding Israel of their rescue from Egypt? What does that ordering tell us? What went wrong with Israel's relationship to the law? How did it become legalism instead of love? What is the 'new covenant' promised in Jeremiah 31:31-34? How is it different from Sinai? How does the law written on the heart change the way you think about obedience?

Introduction

Open by reading the preamble to the Ten Commandments — the part most people skip: 'I am the LORD your God, who brought you out of Egypt, out of the land of slavery' (Exodus 20:2). The commandments begin with a rescue, not a demand. God does not say, 'Obey and I will save you.' He says, 'I have saved you. Now here is what a saved life looks like.'

Read Exodus 19:3-6. Before the law is given, God reminds Israel: 'You yourselves have seen what I did to Egypt... you will be my treasured possession.' The law is a gift to a people already loved, not a contract to earn love.

Preaching note: This sermon needs to rehabilitate the law for people who have only heard it as burden. Help them see it as God's description of the good life — given in grace, received in gratitude.

I. Rescued Before Required (Exodus 20:1-2; Deuteronomy 7:7-9)

The order matters. God rescued Israel from Egypt before He gave them a single commandment. Salvation comes first. Obedience is the response, not the condition.

Deuteronomy 7:7-9: 'The LORD did not set his affection on you and choose you because you were more numerous... but it was because the LORD loved you.' Election is based on grace, not merit.
This is the same pattern we see in the New Testament: 'While we were still sinners, Christ died for us' (Romans 5:8). God acts first. We respond.

Application: Are you trying to obey your way into God's favor? Or are you living out of the favor He has already given? The order of Exodus 20 is the order of the gospel: grace first, then obedience.

II. The Shape of a Loved Life (Exodus 20:3-17)

The Ten Commandments fall into two categories: love God (commandments 1-4) and love your neighbor (commandments 5-10). Jesus summarized them the same way: 'Love the Lord your God... love your neighbor as yourself' (Matthew 22:37-40).

Each commandment protects something precious: God's honor, rest, family, life, marriage, property, truth, contentment. The law is not arbitrary restriction — it is loving protection.
The Sabbath commandment (20:8-11) is unique — it is the only commandment that asks you to stop rather than to act. It is God's gift of rest embedded in the law.

Application: Read the Ten Commandments not as a list of restrictions but as a description of the life God designed for human flourishing. What would your community look like if everyone lived this way?

III. The Law Written on Hearts (Jeremiah 31:31-34)

Israel could not keep the covenant in their own strength. They knew what was right, but they could not consistently do it. So God promised something new: 'I will put my law in their minds and write it on their hearts' (Jeremiah 31:33).

The new covenant does not change the content of the law — it changes the location. External stone tablets become internal heart transformation.
Romans 6:14: 'You are not under the law, but under grace.' This does not mean the law is abolished — it means the power to keep it now comes from grace rather than from human effort.

Application: Do you experience God's law as burden or gift? The new covenant promise is that obedience flows from the inside out — not through gritted teeth but through a transformed heart. If your obedience feels like slavery, you may be living in the old covenant while the new one is available.

Conclusion & Appeal

Close with this: the law was never the problem. Israel's inability to keep it in their own strength was the problem. The new covenant does not erase the law — it internalizes it. God's design for human life has not changed. But now, through the Spirit, He writes it on our hearts so that obedience becomes desire rather than duty.

Challenge: Read the Ten Commandments this week through the lens of grace. For each one, ask: 'How is God protecting me with this command? How is the Spirit enabling me to live this way?' Let law and grace work together the way God always intended.
