The Cross as Dividing Line
Thesis The cross of Jesus Christ is the eternal dividing line where those who see only foolishness and shame are separated from those who, by God's grace, see the King who saves by refusing to save himself—and this reality must remain the defining center of both personal discipleship and the church's life across all generations.
The shape of the argument
29 units across exposition, application, illustration, theological claim, and conclusion. The pastor's argument is built from these moving parts.
- analogy · unit #4 — The continental divide illustration establishes the sermon's controlling metaphor: the cross functions as an invisible but absolute dividing line where seemingly small differences result in radically different eternal destinations, just as water falling on either side of Loveland Pass ends up in completely different oceans.
- personal story · unit #13 — A personal story of watching his newborn son struggle to breathe under a medical bubble illustrates the painful separation between Father and Son on the cross, with a crucial theological qualification that this is not cosmic child abuse since Jesus chose the cross willingly.
- hypothetical · unit #21 — An extended illustration using the three crosses to explain substitutionary atonement—sin is either 'on you' or 'on him'—with a direct evangelistic appeal for the listener to confess Christ and have their sin transferred to Jesus.
- The crucifixion is penal substitutionary atonement: Jesus bore the penalty for our sin as our substitute to restore us to God, and this reality redefines everything in Scripture, reality, and eternity. unit #14

0 · The pastor opens with practical announcements about fellowship events and honoring departing members, establishing relational context before moving into the sermon proper
love, one of our distinctives, is gathering around the table and having food and enjoying fellowship. And for the last couple of years, we've been hindered in being able to do that. And so, uh, we've had some people join in the last 2 years that think like, oh, we just kind of meet and then leave. No, we have a party, like every excuse that we can possibly come up with. So, uh, we are excited to be able to fellowship together next week. Uh, and I want to encourage you, If Tom and Lisa have ministered to you in a specific way over the last many years, please write that down, get that to them in a note so they can take it with them as they head off to Tucson. We would love to bless them in that way. So I know sometimes, like me, like, oh, I wish I should do that. No, you should do it today. Do it today. I think it'll encourage them.
1 · The pastor establishes the authority and reliability of the biblical text by noting Peter's testimony that Scripture is more trustworthy than eyewitness memory, framing the crucifixion account as sacred ground that provides truer sight than physical presence would have
All right, let's turn in our Bibles to Mark chapter 15. Mark chapter 15. Now, as we've discussed, it's very likely that the text of the Gospel of Mark was— many of the accounts were provided by the Apostle Peter working with Mark. But the Apostle Peter, who heard the voice of Jesus and saw Jesus with his own eyes, says that in the Word of God, the phrase he uses is, we have the prophetic word more fully confirmed. Meaning that the Apostle Peter, who saw Jesus with his eyes and heard Jesus with his own ears, believed that this, the inspired, inerrant, living Word of God, was more true than even his own memory. Meaning that as we watch the events of the crucifixion today, in some sense, we see more truly than even the people on the Hill of Golgotha. Church, this is hallowed ground.
2 · The full reading of Mark 15:21-41 presents the crucifixion narrative from Simon carrying the cross through Jesus' death and the responses of the centurion and the women, establishing the textual foundation for the sermon's exposition
Would you stand for the reading of God's word? Mark 15:21, "And they compelled a passerby, Simon, of Cyrene, who was coming in from the country, the father of Alexander and Rufus, to carry His cross. And they brought Him to the place called Golgotha, which means 'place of a skull.' And they offered Him wine mixed with myrrh, but He did not take it. And they crucified Him. And divided his garments among them, casting lots for them to decide what each should take. And it was the third hour when they crucified him. And the inscription of the charge against him read, 'The King of the Jews.' And with him they crucified two robbers, one on his right and one on his left. And those who passed by derided him, wagging their heads and saying, 'Aha! You who would destroy the temple and rebuild it in 3 days, save yourself and come down from the cross.' So also the chief priests with the scribes mocked him to one another, saying, 'He saved others; he cannot save himself. Let the Christ, the King of Israel, come down now from the cross, that we may see and believe.' And those who were crucified with him also reviled him. And when the sixth hour had come, there was darkness over the whole land until the ninth hour. And at the ninth hour, Jesus cried out with a loud voice, 'Eloi, Eloi, lema sabachthani?' My God, which means, 'My God, my God, why have you forsaken me?' And some of the bystanders hearing it said, Behold, he's calling Elijah. And someone ran and filled a sponge with sour wine, put it on a reed, and gave it to him to drink, saying, Wait, let us see whether Elijah will come to take him down. And Jesus uttered a loud cry and breathed his last. And the curtain of the temple was torn in two from top to bottom. And when the centurion who stood facing him saw that in this way he breathed his last, he said, 'Truly this man was the Son of God!' And there were also women looking on from a distance, among whom were Mary Magdalene and Mary the mother of James the younger and of Joses and Salome. When he was in Galilee, they followed him and ministered to him. And there were also many other women who came up with him to Jerusalem. This is God's Word.
3 · A brief pastoral prayer asking God for spiritual sight and hearing as the congregation prepares to engage with the crucifixion account
Father, we pray for sight. We pray to hear your voice. Amen. You may be seated.
4 · The continental divide illustration establishes the sermon's controlling metaphor: the cross functions as an invisible but absolute dividing line where seemingly small differences result in radically different eternal destinations, just as water falling on either side of Loveland Pass ends up in completely different oceans
At 11,990 feet in the mountains of Colorado, there stands an unassuming sign denoting Loveland Pass. It's an unassuming sign that you might miss in the midst of a snowy landscape, but that place bears a unique distinction. If one drop of water falls or one snowdrift melts to the right of the sign, that drop of water will eventually make its way through the water cycle to the Atlantic Ocean. To the left of the sign, if a drop of water or snowdrift falls, it will find its way to the Pacific Ocean because Loveland Pass is on the continental divide of the United States. The continental divide means that there is an invisible line stretching from the top of the United States all the way south through mountain ranges and mountain passes. And scientists have found that on the Continental Divide, if a drop of water falls on this side, goes to the Atlantic, this side goes to the Pacific. And yet it is invisible. You might pass over this divide and not really tell the difference. It might seem like people standing on either side of the sign are standing close together, but a drop of water falling on either side will have a vastly different destiny. Our passage today, in our passage today, the cross is a continental divide, an eternal divide. At the center of the text is Jesus Christ on the cross, and that text is then divided between cruel mockers leading up to the cross and reverence on the other side of the cross from the centurion and the women. And the angels. Everything on one side leads to one place, everything on the other side leads to a radically different place.
5 · This unit traces how Mark has been building toward the crucifixion since chapter 8, establishes the cross as the gospel's climactic moment and central interpretive key, explains the physical and cultural horror of crucifixion, and introduces the sermon's three-part structure organized around different responses to the cross
If the Gospel of Mark were a mountain range, this crucifixion of Jesus is the highest point in the Gospel of Mark, the peak of the mountain. Now, everything has been leading up to this. As soon as Jesus' identity is revealed, as soon as he's seen as the Messiah in Mark chapter 8, Jesus immediately says, He immediately begins to teach clearly that he will be rejected and suffer and die and rise again. And it says, "He said this plainly." And again, he says it in Mark chapter 9. And again, he says it in Mark chapter 10. He repeatedly teaches this, meaning that the cross of Jesus Christ casts a shadow across the entirety of the Gospel of Mark, and it casts its shadow forward into the the rest of the New Testament. The cross is this continental divide in life and in Scripture and in our passage and in the Gospel of Mark. So the question is, how do people looking at the same event believe radically different things? How do they end up in radically different places? And where are we on this continental divide? Now, the phrasing of 1 Corinthians 2, which talks about the cross being foolishness to some, but glory and power to others. Our first section is the foolishness of the cross. The foolishness of the cross. In Jesus' day, the cross was a brutal, shameful, horrific thing. It involved driving iron spikes through someone's wrists and feet, forcing them, leaving them hanging and forcing them to push themselves up their heel, which caused intense excruciating pain, to draw a breath. And they did this repeatedly until they suffocated and died. It was public, it was demeaning, it was shameful, it was reserved for the most vile criminals. And additionally, the Jews considered someone hung on a cross to be cursed according to the teaching of the Old Testament that anyone hanged on a tree is cursed. So as the onlookers saw Jesus hanging on the cross, they saw foolishness, they saw shame. And their mockery reveals so much about what they believed.

Mark 15:39
And when the centurion, who stood opposite him, saw that in this way he breathed his last, he said, 'Truly this man was the Son of God!'
Why this verse: This verse captures the sermon's central claim: the cross is the eternal dividing line where one man sees foolishness and shame, but another—by God's grace—sees the true King and Son of God who saves by refusing to save himself. It is the moment when penal substitutionary atonement becomes visible, and faith is born.
6 questions for your group this week
-
When you read Mark 15:29-32, what specific things do the mockers say about Jesus, and what do their words reveal about what they think the cross means?Mark 15:29-32→ How does their understanding of power and kingship differ from what Mark is actually showing us about Jesus in this moment?
-
Mark tells us that when Jesus died, the centurion who was standing there watching declared, 'Surely this man was the Son of God.' What changed between the mockers' verdict and the centurion's verdict—what did the centurion see that the others missed?Mark 15:37-39
-
Ricky emphasized that the cross is penal substitutionary atonement—Jesus bore the penalty for our sin as our substitute to restore us to God. When you think about your own life, what does it mean practically that Jesus bore a penalty you could not bear yourself?1 Corinthians 2:2→ How should that reality reshape the way you think about your relationship with God?
-
According to the sermon, being present in church or being close to Christians does not save you—personal faith in Christ does. What's the difference between proximity to the gospel and actual trust in Jesus, and where do you see that distinction playing out in the lives of people around you?Romans 10
-
Ricky said the Christian life is a progressive movement of allowing the cross to reshape every area of life. Pick one area—sexuality, marriage, reconciliation, work, how you spend money—and describe what it would look like for the cross's pattern of sacrifice and Christ's ownership to actually reshape that one area for you in the next month.Ephesians 5→ What resistance or difficulty do you anticipate facing as you try to let the cross reshape that area?
-
The mockers saw the cross as the end of Jesus' claim to be King. But Mark shows us the cross is actually the place where Jesus is revealed as King—just not the kind of king the world was expecting. How does this redefine what it means for you to follow Jesus as King in a culture that still mocks the cross?Mark 15:26
5-day reading plan
This week we meditate on the cross as the eternal dividing line—the place where Jesus bore our penalty as our substitute, and where every area of life is reshaped by his sacrifice.
Paul anchors everything—his preaching, his theology, his very identity—on the cross of Christ. When we grasp that Jesus bore the penalty we deserved as our substitute, we stop trying to earn God's favor and start living from the certainty that we are restored to him. The cross is not one doctrine among many; it is the hinge on which all of Christian reality turns.
Peter writes to a persecuted church and calls them to see Christ as the Lamb—the once-and-for-all sacrifice whose death breaks every barrier between us and God. When we understand ourselves as those redeemed by the Passover Lamb's blood, we gain courage to endure suffering, knowing we belong wholly to God. The cross does not promise us comfort; it promises us restoration to God himself.
There is no neutral ground at the foot of the cross. Either we confess Jesus as Lord and believe he rose, or we stand among the mockers who see only foolishness and shame. Proximity to the gospel—sitting in services, having Christian friends—saves no one. We must each personally turn from our sin and embrace Christ as the one who alone can restore us to God.
Because Christ forgave us at the cross—absorbing the penalty we deserved—we are now called to forgive one another in the same way. The cross is not a past event we remember; it is the pattern that rewires how we treat our families, our enemies, our brothers and sisters. Forgiveness flows from the cross, and the cross continually reshapes our entire way of relating.
Paul tells husbands to love their wives the way Christ loved the church—by giving himself up for her, just as he did at the cross. This is not sentimental language; it means the cross becomes the template for how we spend our bodies, our money, our time, our sexuality. Every sphere of life—marriage, work, conflict, desire—is brought under the lordship of the crucified King who gave everything.
The Cross Reshapes All Things
Father, we come before you in awe of the cross of your Son. In that place of shame and seeming defeat, you accomplished what nothing else in heaven or on earth could accomplish—you bore the penalty for our sin, you satisfied your holy wrath, you tore the veil between us and you, and you made a way home for all who believe. We confess that we, like those who stood at the foot of the cross, are often divided in our seeing. We live as if the cross is a historical fact we assent to, yet we order our lives as though it changes nothing. We treat our sexuality, our marriages, our conflicts, our work as if they exist in a separate kingdom from the cross—as if Christ's substitutionary sacrifice reshapes doctrine but not our daily choices. We are slow to let the scandal of the cross—the power of God hidden in weakness, the King who saves by refusing to save himself—redefine everything we touch.
But here is the good news we receive today: the cross is not past. It is the eternal dividing line, the place where you have already answered every accusation against us, where you have already clothed us in Christ's righteousness, where you have already declared us your beloved children (Romans 10:9; 1 Corinthians 2:2). By your grace, we believe. And now we ask: remake us from the inside out. Give us eyes to see what the centurion saw—that Jesus is your Son, your King. Teach us to let the cross reshape how we give ourselves in love, how we forgive one another, how we steward our bodies, how we speak to our children, how we work, how we worship. Make the cross the controlling principle of our whole lives, not just our confession.
Father, guard this church from drifting into a Christianity that preserves the cross in memory but abandons it in practice. Make us a people who return again and again to the foot of Golgotha, not as tourists but as those who have been utterly changed by what happened there. We commit ourselves to you: we are yours, bought with a price, shaped by the One who drank the cup we deserved to drink. To you be the glory, now and forever.
Two Sides of the Cross
This sermon divides the world into two responses to Jesus's death—those who see foolishness and those who see the King who saves. Ask your family which group they're in, and listen for what they think it means to truly see Jesus. The goal is to help them understand that being near Christians isn't the same as believing in Christ yourself.
At the cross, some people saw Jesus as weak and foolish—unable to save himself. But others saw him as the true King who saves by dying for us. When you think about Jesus on the cross, which group are you in? What do you see?
The Cross Reshapes Us Together
- What part of the cross's meaning—that Jesus bore the penalty we deserved so we could be restored to God—stirred something in your heart this week?
- Where in our marriage do we need to let the cross reshape us? Is there a place where we're living as if the cross hasn't changed everything?
- What is one area of our life together—sexuality, forgiveness, how we treat each other—where you want to see Christ's sacrificial love more clearly? How can we pray for that together?
