Thriving in a Secular Age: How Churches Build Gospel Resilience When Culture Rejects Faith

Secularism is the #1 challenge facing North American and European churches today. But resilient faith isn't built by fighting culture - it's built through deep relationships that model and sustain countercultural hope.

Though secularism is rising, Christ as already won.

According to the Lausanne Movement's 2025 global survey of 1,030 church leaders from 119 countries, the cultural dominance of secularism now ranks as the #1 challenge facing Christianity - especially in North America and Europe.

This doesn't mean atheism is attacking the church. It means something subtler and more pervasive: the culture has decided that faith is irrelevant to real life.

Science explains the world. Philosophy addresses meaning. Psychology handles emotional needs. Technology solves problems. If you want to pray privately at home, that's fine, but the public square has moved on. The gospel is relegated to personal preference, not universal truth.

For churches accustomed to cultural Christianity - where faith was assumed, where church attendance was normal, where pastors held cultural authority - this shift represents an earthquake.

But here's what research is showing: The churches thriving in a secular age aren't those fighting hardest to reclaim cultural influence. They're the churches building the deepest relationships - communities where faith is so embodied, so costly, so joyful that it becomes countercultural witness.

Gospel resilience isn't built through argument. It's built through belonging.

The Secularism Crisis Isn't About Arguments

Many churches respond to rising secularism with better arguments. More apologetics. Stronger polemics. Clearer theological defense.

But Tim Keller has noted something important: "Secularism isn't primarily an intellectual problem. It's a relational one. When people no longer know Christians intimately, they stop believing Christianity makes sense."

The Barna Group confirmed this in their September 2025 study: Christians who are embedded in deep relational community demonstrate remarkable resilience, even in hostile cultural environments. Those isolated from authentic Christian friendship lose faith at significantly higher rates.

In other words: Gospel resilience is relational, not just intellectual.

Consider what secularism actually does to faith:

• It makes faith feel optional rather than ultimate
• It normalizes competing worldviews as equally valid
• It provides materialistic explanations for meaning-making
• It offers community through digital connection rather than embodied presence
• It defines success through external metrics (money, status, achievement) that undermine spiritual priorities

A young Christian in a secular culture doesn't lose faith because they lost an argument. They lose faith because they're surrounded by people who assume faith is irrelevant and because they lack deep relationships with people modeling a better way.

Conversely, Christians embedded in tight-knit communities where faith is lived out, where sacrifice is valued, where people know each other deeply - these Christians develop resilience that mere arguments could never provide.

What Resilient Discipleship Actually Looks Like

Gospel Coalition pastor Tom Woodbridge writes about "resilient discipleship" - faith that survives and thrives when culture rejects it. What characterizes resilience?

Resilient Christians have friends, not just acquaintances in the faith.

They know people who genuinely know them. They're part of a community where vulnerability is safe, where confession happens, where accountability is real. Secular culture can't provide this. A person can live in a secular culture, engaged with atheist colleagues and secular entertainment, but if they have even a few deep Christian friendships, their faith remains resilient.

Conversely, isolated church members - people who attend Sunday service but have no close Christian friends - lose faith at accelerated rates when secular pressure increases.

Resilient Christians are engaged in real discipleship relationships.

A Barna study from 2025 found that Christians experiencing relational discipleship (through mentors, small groups, spiritual friendships) are "significantly more likely to remain resilient in their faith." They're "more engaged in Scripture, more consistent in prayer, more active in their churches."

Discipleship that's relational - where real people walk with other real people through the actual struggle of living faith in a secular age - creates resilience. Discipleship that's mass-produced or information-delivered doesn't.

Resilient Christians know why their faith costs them something.

Secular culture offers easier paths: pursue wealth without restriction, pursue relationships without moral framework, pursue meaning through consumption and entertainment. When faith demands sacrifice - saying no to lucrative but ethically compromising opportunities, resisting cultural pressures, investing in community rather than individual advancement - resilient Christians need to know why.

Not just theoretically. But relationally.

A pastor explaining why Christianity requires sacrifice is helpful. A friend demonstrating that sacrifice joyfully, showing that cost produces meaning and joy - that's transformative.

Why Secularism Thrives in Isolation

Here's what secularism actually does: It isolates believers from each other.

This happens through multiple mechanisms:

Cultural pressure toward individualism
Secularism emphasizes personal autonomy, individual choice, self-actualization. Community becomes a nice add-on, not essential. A Christian influenced by secular thought may maintain individual faith while drifting from community.

Normalization of secular alternatives to community
Where the church used to provide primary community (through church gatherings, church socials, church leadership), secular culture now offers: online communities, hobby groups, professional networks, entertainment platforms. People are "connected" without being known.

Suspicion of religious institutions
Scandals in churches (abuse, corruption, hypocrisy) make people hesitant to commit to Christian community. Many young adults maintain nominal faith but avoid church community specifically.

Geographic and social fragmentation
Even Christians who want community struggle to find it. Work sends them to one neighborhood. Friends live in another. Church is in a third. Extended family is scattered. Deep community requires proximity and commitment - luxuries the secular world doesn't encourage.

The result: Believers who might have remained faithful through embedded community instead find themselves isolated, exposed to full secular pressure with no countervailing relational support.

This is why the Gospel Coalition's emphasis on "building kingdom institutions" is so critical. Secular culture thrives in isolation. Gospel culture requires community.

The Barna Research on Resilient Faith

The September 2025 Barna study provides concrete data on what builds resilient faith in a secular age:

56% of Christians engage discipleship community in church
Meaning 44% don't. That's a massive gap. Churches are not providing (or people are not taking advantage of) relational discipleship.

Christians in discipleship relationships show dramatically higher resilience:

• More engaged with Scripture
• More consistent in prayer
• More active in church
• More resilient when facing secular pressure
• More likely to maintain faith through crisis

Relational discipleship requires intentionality
It doesn't happen accidentally. Churches that facilitate mentoring relationships, create small groups designed for depth (not just information transfer), and build cultures where vulnerability and accountability are normal - these churches develop resilient believers.

Isolated believers are significantly more vulnerable
Christians without close Christian friendships, without discipleship relationships, without community accountability are at high risk when secular pressure increases.

This suggests something clear: The churches most likely to maintain faith in a secular age are those building the deepest relationships.

How to Build Gospel Resilience in Your Church

If secularism's victory lies in isolation, then gospel resilience is built through intentional community. Here's how:

Step 1: Diagnose Your Relational Health

Most churches can't identify which members are isolated. They track attendance and giving. They don't track relational connection.

You need to know:

• Which members have fewer than 5 meaningful church friendships?
• Who's been a regular attender but hasn't developed deep relationships?
• Which people are isolated despite high activity levels?

This isn't invasive. It's shepherding. A pastor who can't identify isolated sheep isn't shepherding well.

For frameworks on tracking relational health, see our post on how to identify isolated church members before they leave.

Step 2: Facilitate Deep Relationships Intentionally

Don't hope people connect. Facilitate connection:

• Start mentoring relationships: pair mature believers with younger believers based on personality compatibility and spiritual needs
• Create small groups designed for depth: groups that gather frequently, discuss real struggles, hold each other accountable
• Normalize vulnerability: preach about struggle, share pastoral struggles, create cultures where people can be honest
• Invest in relational apprenticeship: let young believers follow mature believers into real ministry, real struggle, real faith

Step 3: Make Discipleship Relational, Not Just Informational

The difference between resilient and vulnerable believers often comes down to this: relational versus informational discipleship.

Informational discipleship transfers knowledge:

• Classes teaching theology
• Sermons explaining Scripture
• Resources providing information

Relational discipleship walks alongside:

• A mentor wrestling with the same temptations you face
• A small group knowing your particular struggle
• A friend modeling how to live faith countercullturally
• An older believer showing you their own wrestling with faith

Both matter. But resilience comes through relational discipleship.

Step 4: Create Culture Where Cost is Celebrated

In a secular age, Christian faith costs something. It costs money to tithe when consumer culture demands spending. It costs time to prioritize community gathering over individual pursuits. It costs social capital to witness to faith in hostile environments.

Resilient churches openly acknowledge this cost and celebrate the joy that comes through paying it.

• Tell stories of believers who chose faithfulness over financial gain
• Celebrate people who sacrificed for gospel priorities
• Be honest about what faith requires
• Show how that cost produces deeper meaning and joy

When people understand why they're sacrificing, they develop resilience to maintain that sacrifice when secular pressure increases.

Step 5: Build Relational Accountability Structures

Secular culture says: "Your beliefs are personal. Don't impose them on others." Gospel culture says: "We're bound together in community. We hold each other accountable."

These are opposites.

Resilient churches need accountability:

• Discipleship relationships where people report on spiritual progress
• Small groups where confession and prayer for one another happen
• Leadership structures where leaders are known by the community they lead
• Mentoring relationships where growth is tracked and celebrated

This isn't judgmental. It's loving. It's what community actually does.

See our post on discipleship tracking for small churches for practical ways to implement relational accountability.

What Francis Chan Means by "Fierce Community"

Francis Chan, in "Letters to the Church," calls believers to "fierce community" - relationships so deep, so committed, so loving that they become powerful countercultural witness against secular isolation.

This kind of community:

• Prioritizes gathering over entertainment
• Values vulnerability over image management
• Practices confession and forgiveness
• Knows people intimately, not superficially
• Holds each other accountable to gospel values
• Celebrates sacrifice for kingdom purposes
• Grieves together and celebrates together

Secular culture can't replicate this. No app, no algorithm, no entertainment platform can provide genuine fierceness - commitment that says "I'm bound to you not because it benefits me individually, but because you matter to God."

Churches that build this kind of community become powerful witnesses precisely because they contradict everything secular culture teaches about fulfillment through individualism.

The Gospel Coalition on Building Kingdom in a Secular Age

The Gospel Coalition recently published a piece titled "How Ordinary Christians Can Build Kingdom Institutions in 2025." The central insight: "Now is the time to build, not tear down."

In a secular age, the temptation is to retreat, defend, or deconstruct. But Gospel Coalition leaders call instead for building - particularly for building communities that model and live out gospel values so compellingly that they become witness.

This means churches aren't primarily fighting secularism through argument. They're transcending it through relational beauty.

When a secular observer sees a community where:

• People know each other deeply
• Vulnerability is safe
• Forgiveness is practiced
• Sacrifice is celebrated
• Joy is genuine
• Love is costly

They see something their secular worldview can't explain or replicate. That becomes witness. That builds resilience in believers.

Moving From Defense to Resilience

Many churches approach secularism defensively. We're losing influence. We're being persecuted. We need to fight back culturally.

But resilient churches approach it differently. We're building deeper community. We're making disciples more robustly. We're creating cultures where faith isn't just believed but lived, embodied, and transmitted through relationship.

Gavin Ortlund calls this "Christian leadership that avoids branding and exploiting and instead explores the fullness of Christ." In a secular age, that fullness is demonstrated through relational depth that secular culture can't provide.

Conclusion: Resilience Through Belonging

The #1 challenge facing churches in a secular age isn't intellectual. It's relational.

Young believers in a secular culture need to know Christians intimately. They need to see faith lived out joyfully despite cost. They need discipleship that walks with them through struggle, not just information about faith. They need community fierce enough to contradict everything secular culture teaches about fulfillment.

Tim Keller said it best: "Secularism prospers in isolation and dies in community."

That's not a strategy. That's a description of how gospel faith actually survives and thrives when culture rejects it. Through relationship. Through belonging. Through community so deep that it becomes countercultural witness.

The churches building that kind of community will not just survive secularism. They'll thrive. And they'll demonstrate to a secular age what Gospel resilience actually looks like.
