What the sermon argues

The shape of the message

Western culture has largely lost not only a Christian mind but any coherent mind at all, succumbing instead to mindlessness driven by materialism, relativism, and television's image-based medium. Paul's command in Romans 12:1-2 to be transformed by the renewing of our minds stands against this cultural conformity and requires us to think Christianly about everything—not merely to think about Christian things, but to interpret all of reality through a biblical framework rather than through the secular lens that dominates modern thought. A Christian worldview begins with the doctrine of God—a personal, holy, sovereign being who reveals himself in Scripture—and stands opposed to the naturalism that has replaced theism in the West, producing a culture that cannot distinguish good from evil and increasingly behaves like animals rather than image-bearers. Only those willing to lose their lives for transcendent truth make a difference in history, as seen in the collapse of communism in 1989, where Christians defied death because they believed in a reality beyond this world.

Questions for midweek

  1. What does Paul mean in Romans 12:1-2 when he calls believers to 'not be conformed to this world' but instead to be 'transformed by the renewing of your mind'? What worldly patterns of thinking do you see most pressuring the church today? Romans 12:1-2
    Can you think of a specific area—politics, sexuality, work, money, entertainment—where secular thinking has subtly shaped how you think differently than Scripture would?
  2. Boice argues that a Christian mind begins with 'the doctrine of God'—understanding him as personal, holy, and sovereign, revealing himself in Scripture. How does viewing God this way change the way you interpret what you see happening in the world around you? Romans 1:18-20, Psalm 19:1
  3. The sermon traces how Western culture has moved from a theistic worldview (believing in a personal God) to a naturalistic worldview (seeing only matter and no transcendent reality). What are the practical differences you observe in how people make moral decisions under each framework?
    Where do you see this naturalism affecting decisions in your own workplace, school, or family relationships?
  4. Romans 1:28-32 describes a progression of God's judgment: people suppress the truth, exchange God's glory for idols, and finally God gives them over so they 'call evil good and good evil.' How does understanding this progression help you make sense of cultural confusion about morality? Romans 1:28-32
    What does it mean pastorally and spiritually that this represents God's judgment rather than merely human foolishness?
  5. Boice contrasts Daniel Garva, who was willing to lose his leg for transcendent truth, with a Princeton student who declared 'nothing is worth dying for.' What does this difference reveal about what we actually believe is real and true? How does a Christian worldview reshape what we consider worth sacrificing for? Hebrews 11
    Where in your own life are you being called to choose a transcendent value over earthly comfort or safety?
  6. The sermon argues that developing a Christian mind means learning to think about *everything*—not just explicitly 'Christian' topics—through a biblical framework. What would it look like for you to begin applying a Christian worldview to decisions about your work, entertainment choices, or how you spend money this week? Romans 12:3
    What spiritual practices or habits would help you actually do this rather than merely intending to?
Daily readings

Five-day reading plan

This week we trace the foundation of a Christian mind: from God's revealed glory in creation, through the catastrophe of human rebellion and cultural decay, to the call to recover biblical theism and think Christianly about all of life.

Monday
The Christian worldview sees creation declaring God's glory, while secularists see only the cosmos itself.Psalm 19:1
The heavens declare the glory of God—not the glory of physics or matter or chance, but of a personal, intentional Creator. When we recover this vision, we begin to think Christianly: we see purpose, design, and divine intent woven through all reality. This is the foundation upon which a Christian mind is built.
Tuesday
We live in a mindless society shaped by materialism and skepticism that has rejected knowledge of God.Romans 1:21-23
Paul diagnoses our cultural condition with precision: humanity has deliberately suppressed what it knows of God and exchanged the glory of the eternal God for images of created things. This is not ignorance—it is willful rebellion that produces spiritual blindness. Our task is to resist this inversion and recover the ability to think truthfully about what is real.
Wednesday
When a civilization rejects God, it descends into insanity; God's judgment takes the form of madness that treats the human as merely animal.Daniel 4:30-33
Nebuchadnezzar's humiliation—cast down to eat grass like a beast—illustrates what Paul later calls the judicial blindness of Romans 1:28. A worldview that denies God's sovereignty inevitably produces behavior that is insane, inhuman, beastlike. We see this same descent in our own age when culture celebrates the image-bearer while denying the Image-Giver.
Thursday
Humanity bears the image of God and is crowned with glory and honor, yet this dignity is lost when we refuse to look up to our Creator.Psalm 8:3-8
The psalmist marvels that God has made us "a little lower than the heavenly beings and crowned us with glory and honor." Yet this crown is invisible to those who look only downward, who see themselves as evolved animals rather than divine image-bearers. A Christian mind restores this vision: we are creatures made for transcendence, accountable to God, destined for eternity.
Friday
Only people willing to die for transcendent realities—who hold a Christian worldview valuing eternity over the present world—make a significant difference in history.Hebrews 11
The hall of faith catalogues those who "saw and greeted" the promises from afar, who "acknowledged that they were strangers and exiles on the earth." This is the mind that changed history: a refusal to conform to earthly kingdoms because of allegiance to a heavenly one. We too must recover this willingness to lose our lives for Christ and His kingdom, knowing that only such conviction reshapes the world.
Weekly prayer

Renew Our Minds in Biblical Truth

Father, we come before you acknowledging that you alone are the personal, holy, sovereign God who governs all things toward their appointed end. We confess that we have too often allowed our minds to be shaped by the materialism and relativism of our age rather than by the renewing power of your truth. Like the culture around us, we find ourselves susceptible to mindlessness—absorbed in images and surface-level thinking, forgetting that we are called to interpret all of reality through the lens of your revealed Word rather than through secular frameworks that deny your existence and your reign (Romans 12:1-2).

Yet the gospel declares that we have been given the mind of Christ. Through his death and resurrection, he has broken the power of the worldview that reduces us to mere animals and has restored us to our true dignity as image-bearers of God. In Christ, we are no longer slaves to the patterns of this age but are being transformed into people who see creation declaring your glory, who recognize your hand in history, and who understand that transcendent realities matter infinitely more than temporal comforts (Romans 1:18-20; Psalm 19:1).

Grant us, we pray, the courage and discipline to develop minds shaped by biblical truth. Help us to read deeply, to think carefully about how the gospel speaks to every dimension of our lives—not merely religious matters, but politics, art, work, and culture. Free us from the tyranny of images and mindlessness; teach us to look up to you rather than down at the world's empty philosophies. Give us conviction like those faithful ones whose willingness to die for transcendent truth changed the course of history, that we might live as those who belong to an eternal kingdom and think accordingly (Romans 12:2; Daniel 4).

We commit ourselves to this glad pursuit of a Christian mind, trusting that as our thoughts are renewed by your Word, our entire lives will be transformed to reflect the beauty and truth of Jesus Christ, in whose name we pray.

Memorize

Romans 12:1-2

“I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what the will of God is, what is good and acceptable and perfect.”
This passage is the textual foundation of the entire sermon's argument—Paul's direct command to resist cultural conformity and renew the mind forms the biblical basis for developing a Christian worldview that interprets all reality through Scripture rather than secular naturalism. Memorizing this verse anchors the listener to the apostolic imperative that underlies everything Boice teaches about thinking Christianly.
Family table

Looking Up or Looking Down

One question for the table: Pastor James said that when people stop believing in God, they start acting more like animals instead of like people made in God's image. Can you think of something you saw today—maybe on TV, at school, or online—where someone was acting like an animal instead of like someone made by God? What would it look like if that person remembered they were made to reflect God instead?

Works for ages 8+ — younger kids can listen and offer simple examples with help from parents

For parents: This prompt invites kids to think about the sermon's key contrast: whether we see ourselves as image-bearers made by God, or as animals with no higher purpose. Listen for where your kids naturally place themselves and gently help them see how the gospel calls us upward.

Couples

Renewing Our Minds Together

  1. What part of the sermon most challenged how you're currently thinking about the world—and where do you sense the Holy Spirit calling you to think more biblically?
  2. Where do we, as a couple, tend to drift into secular thinking rather than viewing life through a Christian worldview, and how might we help each other resist that drift?
  3. As we consider the cost of living for transcendent truth rather than merely earthly comfort, what specific conviction would you like the other to pray for you about this week?
