Two Mountains: One Mandate
Thesis Christians have moved from Mount Sinai (terror under the Law with Moses as mediator) to Mount Zion (peace in the Gospel with Jesus as mediator), but the mandate to worship God alone has not changed — only now we are empowered by the Holy Spirit who writes the Law on our hearts and fuels obedience through remembrance and gratitude.
The shape of the argument
6 units across exposition, application, illustration, theological claim, and conclusion. The pastor's argument is built from these moving parts.
- Believers in Christ have not come to the terrifying mountain of Sinai but to Mount Zion, the mountain of peace, angels, and the mediator Jesus — a fundamentally different covenant experience. unit #2
- Throughout redemptive history, God has given us two mountains — Sinai (terrifying) and Zion (peaceful) — representing two covenants, and the details of Sinai's terror exist so the New Testament can announce the superiority of Zion. unit #3
- You cannot reach Mount Zion (the peace of the Gospel) without first passing through Mount Sinai (the terror of the Law) — unless you have been undone by God's righteous requirements and seen your inability to stand before Him, you have not truly become a Christian. unit #5

0 · Announces the sermon series on the Ten Commandments and frames the day's focus: not the commandments themselves yet, but the setting in which they were given
Our kids to children's ministry. And if you'll open your Bibles to the book of Exodus, we're in chapter 19 today. Exodus, chapter 19. We are beginning this sort of miniseries in which we'll focus on the Ten Commandments over the next 10 weeks. And what we'll do today is look a little bit at the first commandment, but we really need to pay kids careful attention to the setting in which the law is given, in which the Ten Commandments are given. There's a lot of attention in the text, actually, not just to the Ten Commandments themselves, but to the environment in which they were given, the scenery in which the Ten Commandments were given.
1 · Describes the terrifying theophany at Sinai — smoke, fire, lightning, trumpet, and a divine warning not to approach or die
I read one part of that to you as we were standing together. This idea that the mountain was full of smoke. It said it smoked like a kiln. The fire of the Lord had descended on this mountain, and it was just this. There was lightning. Have y' all seen those videos of a volcano where there's lightning coming out of the volcano? It's something like that comes to mind. Something terrible, something gloomy, something very frightening, but also just glorious at the same time. And the great concern of the text is, tell the people not to draw near because the Lord has descended on this mountain and. And if they draw near, they'll die. We see again after the Ten Commandments are given. In verse 18 of Exodus 20, we see this. This is right after the Commandments are given. Now, when all the people saw the thunder and the flashes of lightning and the sound of the trumpet and the mountain smoking, the people were afraid and trembled, and they stood far off and said to Moses, you speak to us, and we will listen, but do not let God speak to us, lest we die. Moses said to the people, do not fear, for God has come to test you that the fear of him may be before you, that you may not sin. The people stood far off while Moses drew near to the thick darkness where God was.
2 · Introduces Hebrews 12:18-24 as the interpretive key to Exodus 19
And so I don't want to go too far into this conversation about the Ten Commandments without doing a bunch of work that sort of lays out sort of the fundamental scenery that's involved here. We've got this terrible, smoky, fiery, dangerous, deadly trembling kind of scene set before us. And what do we do with that? Why does the Bible tell us about this? What do we do with it? What are we supposed to think about this? And so on and so forth. Well, we have a text, just like we did last week. We have a text in the New Testament that tells us how to think about this. Stuff. And we can look there in Hebrews 12:18. If you'll turn in your Bibles to Hebrews 12:18, we've got a New Testament text that tells us how to think about this scenery that we're told about in Exodus 19:20. So look at Hebrews 12:18, 24. In Hebrews 12:18 24, we have for you have not come to what may be touched. A blazing fire and darkness and gloom, and a tempest, and the sound of a trumpet and a voice whose words made the hearers beg that no further messages be spoken to them. So here we have a New Testament commentary on this Old Testament moment that we read about just a moment ago. You have not come to the same kind of mountain that you came to before that the Hebrews came to in the Exodus. You've not come to what may be touched. A blazing fire and darkness and gloom, and a tempest and the sound of a trumpet and a voice whose words made the heavens beg that no further message made the hearers beg that no further messages be spoken to them, for they could not endure the order that was given. If even a beast touches the mountain, it shall be stoned. Indeed, so terrifying was the sight that Moses said, I tremble with fear. So that's how the writer of Hebrews is summarizing what we just read in Exodus. Seems fair, seems accurate. It's the same thing we just read. But he says, you haven't come to that mountain if you're in Christ. You've come to a different mountain. Look at verse 22 of Hebrews chapter 12. But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering, and to the assembly of the firstborn who are enrolled in heaven. And to God, the judge of all, and to the spirits of the righteous made perfect. And to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel.
3 · Proposes the sermon's controlling typology: two mountains across redemptive history (Sinai/Horeb and Zion/Jerusalem), both sites of divine descent but representing two fundamentally different covenant experiences
So what we've got here is throughout all of redemptive history, we've got two mountains put before us. And one is called Sinai. It is also sometimes called Horeb. And then the other mountain is called Zion, or sometimes called Jerusalem. So we've got two mountains, and they're both mountains that God has descended upon. All right? And we want to get a sense for why we're given the data we're given in Exodus 19. Why are we told about the smoke and the thunder and the lightning and everything else? And one of the answers to that is so that the writer of Hebrews could later say, there's a different mountain in this different covenant. And unlike the old mountain, this one is not terrifying. Okay, so do you see that? You've got two mountains in biblical history, Sinai. And you've got Zion, two mountains.
4 · Word study on Sinai/Horeb (thorny, hateful, dried up, devastated) versus Zion/Salem (permanence, peace)
Now, let's look just at the meaning of these words. Okay, first of all, so we've got the Old Covenant, which is the law represented with this one mountain, Mount Sinai. And the word Sinai means thorny. It can even mean hateful. It carries the idea of harshness. Okay, so Sinai means harshness, thorniness, hardness. The word horeb, which is also sometimes used to describe this particular mountain where the Ten Commandments was given, is the word that means to be dried up, to lay waste, to devastate, something like that. So that's what Sinai means. Thorny, hateful, dried up, devastated. Well, that's kind of what we just read. It was this terrible kind of experience for the people that were there. When they heard the voice of the Lord, they immediately said, no more. Please just talk to Moses and he'll let us know what you had to say. We can't even bear to hear what you're saying. And that's representative of the Old Covenant, the law. And what does the New Covenant have for us? Well, the word Zion means permanence, marker, monument. And then Jerusalem, the word Salem, it means peace. And so you've got these two different pictures of the program that God has set before the world. The first is the Law, which is the place of trembling. It's the place of harshness. It's the place, place of trial and difficulty, where you stand before God's righteous requirements and you don't pass, you don't measure up. And then the second mountain, Mount Zion or Mount Salem, is the place of permanence and peace. It can't be shaken because everything's been satisfied. The second covenant is the covenant of satisfaction.
5 · Asserts the necessity of passing through Sinai to reach Zion — both geographically in the Exodus narrative and spiritually in Christian conversion
Now, one of the things that we should understand is that you have to move from one mountain to the other. If you are a Christian, if you think you're a Christian and you've never actually been undone and utterly kind of stripped away of all of your righteousness and really trembled before the Lord and realized, I am not a good person and I have to. I cannot stand in the day of judgment on my own accord, then you haven't been to Mount Sinai. And of course, in the story, which is a theological principle carrying through the story, you have to go through Sinai to get to Zion. Does that make sense. You have to. Like in the story, you have to go. God's leading them home to the promised land, to the place of grace. The promised land is typified by vineyards you did not plant, cities you did not build, so on and so forth. It's a place of unmerited favor. It's a place of peace. But to get to that place, you have to stop at Sinai and get your face peeled off with the law, right? Like there's really no other way to do this.

6 questions for your group this week
-
In Hebrews 12:18-24, the writer contrasts two mountains—Sinai and Zion. What specific details does the text use to describe the terror of Sinai, and what do those details reveal about God's character and His standard of righteousness?Hebrews 12:18-24→ Why do you think the sermon emphasizes that we need to feel the weight of Sinai's terror before we can truly appreciate Zion's peace?
-
The sermon claims that 'you cannot reach Mount Zion without first passing through Mount Sinai'—that the Law must undo us before grace can save us. What does it mean to be 'undone by God's righteous requirements,' and can you describe what that looked like in your own journey toward faith?
-
How does understanding the two mountains help us see the Old Testament Law not as God being harsh or arbitrary, but as serving a redemptive purpose in God's plan?→ What shifts in how we read and apply the Old Testament when we grasp that its details exist partly to amplify Sinai's terror so that Zion's peace can be announced as superior?
-
The sermon emphasizes that believers have 'not come to the terrifying mountain of Sinai but to Mount Zion, the mountain of peace, angels, and the mediator Jesus.' In your own experience of Christian life, where do you sense that you're still living as though you must satisfy Sinai's demands rather than resting in Zion's peace?Hebrews 12:18-24
-
What does it mean that Jesus is 'the mediator' between us and Mount Zion? How does His work fundamentally alter our relationship to the Law and to God's justice?→ How should the reality that Christ has satisfied the demands of Sinai on our behalf shape the way we think about obedience and holiness this week?
-
If someone in our church says, 'I feel like God is always angry with me, and I can never measure up,' what would you want them to understand about these two mountains, and how would you point them toward the gospel?
5-day reading plan
This week we trace the arc from the terror of Sinai to the peace of Zion, learning how the Law's demands drive us to Christ and how the Gospel's superiority transforms our entire covenant experience.
The people's response—trembling, requesting distance from God's voice—shows the Law's design: not to save but to expose our helplessness before His holiness. We cannot approach God on the basis of our obedience; the Law's thunder drives us to seek a mediator. This terror is mercy, for it strips away false confidence and prepares us to receive grace.
The contrast is stunning: no fire, no darkness, no sound so terrible we beg to hear no more—instead, myriads of angels, the assembly of the firstborn, and Jesus Himself as mediator of a new covenant. This is not a lesser covenant cheaply attained; it is the destination the Law pointed toward all along, now opened to us through Christ's blood.
God speaks to Israel with tenderness before He thunders from the mountain: 'You have seen what I did to the Egyptians, and how I bore you on eagles' wings' (Exodus 19:4). The Law comes not as punishment for already-saved people but as a tutor to lead us to Christ. The terrifying mountain was always meant to be a stepping stone, never a destination.
We do not approach this mountain through moral effort or ceremonial performance; we approach through the finished work of Christ. His blood does what the blood of bulls and goats could never do—it cleanses our conscience and grants us permanent access to God's presence. The peace of Zion is not earned; it is mediated and given.
Moses' word to the trembling people—'Do not fear; God has come to test you, that the fear of him may be before you' (Exodus 20:20)—reveals that the terror serves a purpose: to teach us reverence and allegiance that flows from grace, not from compulsion. When we grasp our utter helplessness before Sinai, we run to Zion. Have we truly encountered the gospel until we have been undone by the Law and remade by Christ?
Prayer for Grace to Stand at Zion
Father, we stand amazed at the contrast You have set before us in Your Word — the terrifying mountain of Sinai with its smoke and fire, and the peaceful mountain of Zion where Jesus stands as our mediator. We confess that we often fail to grasp the magnitude of this mercy. We live as though we do not fully understand that we have been delivered from the terror of the Law, that we have been transferred from condemnation to acceptance, from fear to the embrace of our Savior's love (Hebrews 12:18–24). Forgive us for our forgetfulness and our persistent anxiety, as though we still stood at the foot of Sinai awaiting judgment.
We thank You that in the gospel, Christ has borne the full weight of God's righteous requirements in our place. He has passed through the terror we deserved, satisfied the Law we could never keep, and opened a way for us to draw near to You in peace. By His substitutionary work, we have become children of grace rather than children of wrath, and this is not our achievement but Your gift (Exodus 20:18–21; Hebrews 12:22–24).
Grant us, we pray, the grace to live as though we truly believe we are at Mount Zion and no longer under the shadow of Sinai. Give us courage to approach You with confidence, knowing we are welcome in Christ. Teach us to remember the terror of the Law not to condemn ourselves but to deepen our gratitude for the gospel. And compel us, as we taste this peace, to herald to others the news that Jesus alone is the way from the mountain of judgment to the mountain of grace. To Him be all glory, honor, and praise forever.
Two Mountains, One Journey
This prompt invites your family to reflect on the sermon's central image — the terrifying mountain of God's law (Sinai) versus the peaceful mountain of Jesus (Zion). Help your kids see that understanding how scary God's holiness is actually helps us appreciate how amazing Jesus's peace really is.
In the sermon, we heard about two mountains — one with thunder and fire that made people afraid, and one with Jesus where we can come close to God without being scared. Can you think of a time when you were really scared of doing something wrong, and then someone you trusted made it okay? How is Jesus like that person for us?
From Terror to Peace: Our Gospel Journey Together
- What did Chris's description of Mount Sinai—its terror and our inability to stand before God's holiness—stir in your own heart this week? Where did you feel the weight of that conviction?
- How does it change the way we see our marriage when we remember together that we've both been undone by the Law and now stand together at Mount Zion, clothed in Christ's righteousness rather than our own efforts?
- What is one way you've seen the gospel's peace working in your spouse's life, and how can you pray this week that Christ's mediating work would deepen their assurance and joy?
Hebrews 12:22-24
But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering, and to the assembly of the firstborn who are enrolled in heaven, and to God, the judge of all, and to the spirits of the righteous made perfect, and to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel.
Why this verse: This passage is the sermon's theological anchor, explicitly contrasting Mount Zion with Mount Sinai and presenting Jesus as the mediator who brings believers into a fundamentally different covenant experience. It crystallizes the sermon's central claim that the gospel moves us from terror to peace through Christ's mediation.
