The Crisis of the Interior Life

The Numbers Tell a Story

Here’s what the latest research reveals: 56% of U.S. Christian adults say their spiritual life is entirely private. And here’s the kicker: those who hold this view are significantly less likely to report regular time with God, a strong sense of spiritual progress, or a belief that their faith is very important in daily life.

Let that sink in for a moment. More than half of Christians believe their faith is a completely private matter. And when faith becomes private, it becomes weak.

But there’s a twist in this story. Bible reading is actually up - risen to 42% of adults reading Scripture weekly, the highest in over a decade. Young men are leading this surge. Gen Z men showed a 15-percentage-point jump in commitment to Jesus between 2019 and 2025.

So we face a paradox: interest in Jesus is rising, but disciplined pursuit of holiness isn’t keeping pace. People are reading the Bible more but believing it less. They’re curious about Christ but confused about what spiritual maturity actually looks like.

Half of churchgoers can’t even identify how their church defines spiritual maturity. Less than one in four Christians is currently being discipled by someone. Only 13% participate weekly in prayer groups or Bible studies.

The headline? We have spiritual openness without spiritual depth.

What Baxter and Wesley Saw Coming

Richard Baxter faced this same problem in 17th-century England. He inherited a parish full of people who attended church but whose lives showed little evidence of genuine conversion or ongoing sanctification. They knew the forms of religion but not the power of it.

His solution wasn’t to preach harder sermons and hope for the best. He went house to house. 800 families. Every single one. He examined their spiritual state personally, catechized them, applied Sunday’s sermon to their particular circumstances, prayed with them in their homes.

Why? Because Baxter understood what many have forgotten: spiritual formation requires both structure and relationship. You can’t mature in isolation. You can’t grow strong in privatized faith. You need the means of grace - Scripture, prayer, worship, communion - and you need them practiced consistently in community where people actually know you.

John Wesley saw the same pattern a century later. Nominal Christianity everywhere. People attending services but unchanged in character. So he created the class meeting, small groups of about twelve people who met weekly for ruthless accountability.

They asked each other: What known sins have you committed? What temptations have you faced? How did God deliver you? What are you doubting?

These weren’t comfortable conversations. They weren’t “how’s your week going?” small talk. They were surgical examinations of the soul. And they worked. Because Wesley understood what the research confirms: faith that stays private stays shallow.

The Root Problem

Here’s what’s happening. Some of us have reduced Christianity to a personal consumer choice rather than comprehensive discipleship. We’ve made Jesus our Savior without making him our Lord, which is functionally soothing, but ontologically impossible. We want the benefits of faith - forgiveness, comfort, hope - without the demands of discipleship.

So we show up on Sunday, consume the sermon like a TED talk, maybe sing a few songs, then go home and live the other six days exactly like our unbelieving neighbors. Our “spiritual life” is a compartment we visit weekly, not the foundation that shapes all of life.

The research bears this out. Faith’s importance in daily life has dropped 20 percentage points since 2000. Only one in three Christians says they feel a responsibility to share their faith. When asked what spiritual maturity looks like, most can’t answer.

We’ve lost the script. We’ve forgotten what we’re aiming for. We’re running a race without knowing where the finish line is.

And here’s the honest truth: you can’t become what you can’t define. If you don’t know what spiritual maturity looks like, you’ll never get there. You’ll just drift, hoping somehow you’re making progress, never sure if you’re actually growing or just getting older.

What Scripture Actually Teaches

Jesus prayed in John 17:17: “Sanctify them in the truth; your word is truth.” Notice that word, sanctify. Present tense. Ongoing. God is actively making you holy through his truth.

But sanctification isn’t automatic. It’s not something that happens by spiritual osmosis just because you showed up at church. Paul tells Timothy: “Train yourself for godliness” (1 Timothy 4:7). There’s effort involved. Discipline. Intentionality.

Hebrews 10:24-25 commands us: “Let us consider how to stir up one another to love and good works, not neglecting to meet together, as is the habit of some, but encouraging one another.”

Notice the assumption: you’re part of a specific community where people know you well enough to stir you up, where you’re present consistently enough to encourage others. This isn’t casual attendance. This is covenant commitment.

The writer of Hebrews continues in 13:17: “Obey your leaders and submit to them, for they are keeping watch over your souls, as those who will have to give an account.”

Watch over your souls. That requires relationship. Proximity. Knowledge. You can’t watch over someone you never see. You can’t give an account for someone who remains anonymous.

The Path Forward

So how do we move from privatized, shallow faith to the kind of robust, transformative Christianity that Scripture describes and history validates?

First, reject the lie that your spiritual life is entirely private. It’s not. It’s personal, but not private. You were made for community. You need brothers and sisters who know your struggles, ask you hard questions, and won’t let you drift. Find them. Join a small group. Get in a band meeting. Submit yourself to real accountability.

Second, practice the means of grace consistently. Don’t just read the Bible when you feel like it. Develop a daily rhythm. Even if it’s just ten minutes. Even if you don’t “feel” anything. You’re not waiting for inspiration, you’re positioning yourself where God’s grace can reach you.

Third, get clarity on what you’re aiming for. What does spiritual maturity actually look like? Galatians 5:22-23 gives you the fruit of the Spirit: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control. That’s the target. Not activity. Not busyness. But character that increasingly reflects Christ.

Fourth, find someone to disciple you and someone you can disciple. Less than a quarter of Christians are in either relationship. Be different. Seek out a mentor who’s further along the path. And find someone younger you can pour into. This is how faith gets transmitted - person to person, life to life.

Fifth, stop treating church like a vendor and start treating it like family. You don’t bounce from family to family when someone disappoints you. You commit. You stay. You work through conflict. You bear each other’s burdens. That’s covenant, not contract.

The Key Principle

Your interior life, the state of your soul before God, is the wellspring from which everything else flows, and it cannot be cultivated in isolation but requires the means of grace practiced consistently in accountable community.

This is Practical Christianity. Not vague spiritual aspiration but concrete practices that form you into Christ’s image. Not privatized faith that withers in isolation but social holiness that grows strong through mutual encouragement and accountability.

The research shows we’re at a crossroads. Interest in Jesus is rising, especially among younger men. Bible reading is up. But without the structures to form that interest into mature discipleship, it’ll fade like every other spiritual fad.

We need what Baxter and Wesley knew: clear teaching + structured encouragement and accountability + patient pastoral care = disciples who actually look like Jesus.

The harvest is ready. But we need laborers who know how to form souls, not just count conversions.

Reflect

• Head: What does spiritual maturity actually look like? Can I describe it clearly? If not, how will I know if I’m growing?
• Heart: Have I treated my faith as entirely private? Where do I need the courage to invite others into my spiritual struggles and growth?
• Hands: What’s one concrete step I’ll take this week to move from isolated faith to accountable community?

This Week

Choose one person this week and ask them: “Would you be willing to meet regularly to talk about our walks with Christ? Not superficially, but honestly: struggles, victories, what God’s teaching us?”

And commit to one daily practice of the means of grace, even if it’s just ten minutes of Scripture and prayer before your day begins. Not when you feel like it. Daily.

Closing Prayer

Father, forgive us for treating our faith as private when you’ve called us to community. Forgive us for settling for shallow spirituality when you’ve offered deep transformation. Give us courage to be known. Give us discipline to practice the means of grace. Give us clarity about what we’re becoming. Form us into the image of your Son, not through our effort alone but through your Spirit working in us as we position ourselves where your grace can reach us. For your glory and our good. Amen.

• Christianity is practical because Christianity is true.
• Christianity is practical because Christianity works.
