Many modern churches function like spiritual incubators.
They are warm.
They are welcoming.
They are safe.
And none of that is wrong.
But an incubator is meant to be temporary.
It exists to stabilize someone until they are strong enough to live on their own.
Yet in many churches today, believers remain in a perpetual infant stage — not because God is withholding truth, but because they are rarely invited into it.
Messages stay surface-level.
Sermons recycle familiar themes.
Identity in Christ is mentioned, but not taught deeply.
The result?
Churches filled with sincere believers who love Jesus — yet struggle to understand who they are in Him.
Hebrews Already Diagnosed This Problem
The writer of the Epistle to the Hebrews confronted this exact issue:
“Though by this time you ought to be teachers, you need someone to teach you again the elementary principles of the oracles of God… you have come to need milk and not solid food.” (Hebrews 5:12)
These believers had been walking with Christ long enough to be grounded in truth.
Instead, they still needed basics.
Not because revelation was unavailable.
But because they had become dull of hearing.
Comfort replaced hunger.
Familiarity replaced pursuit.
Surface Teaching Produces Identity-Weak Believers
Much of modern preaching is designed to be:
- seeking what God has already provided.
- emotionally uplifting
- easy to consume
Again — none of this is inherently wrong.
But when this becomes the entire spiritual diet, believers never grow into their identity in Christ.
They learn:
- how to feel better about their week
- how to cope with stress
- how to stay positive
But they don’t learn:
- how Christ fulfills the whole Bible
- what righteousness in Christ actually means
- how union with Jesus reshapes everything
- how to rightly handle Scripture
- how to live from sonship instead of striving
So many believers remain unsure of who they are.
They love God — but don’t understand grace deeply.
They read the Bible — but don’t know how to interpret it.
They attend church — but never become rooted in Christ’s finished work.
Not because they don’t care.
Because they were never taught.
Babies Aren’t the Problem — Staying Babies Is
Spiritual infancy is normal at the beginning.
Hebrews doesn’t condemn infancy.
It challenges permanence.
Babies need milk.
But mature sons need solid food.
Hebrews 5:14 says maturity comes to those who:
“because of practice have their senses trained to discern good and evil.”
Notice:
Growth doesn’t happen automatically. It comes through continued exposure to God’s Word.
Through learning to think biblically.
Through letting truth reshape identity.
Church environments that avoid depth unintentionally train believers to stay shallow.
Why Many Churches Avoid Going Deeper
Let’s be honest.
Deep teaching takes time.
It requires patience.
It risks discomfort.
So many churches choose safety:
- inspirational talks instead of Scripture-rich teaching
- topical series instead of unfolding entire passages
- motivational language instead of theological clarity
But Hebrews shows us something sobering:
Without solid food, believers lose discernment.
Without doctrinal grounding, assurance weakens.
Without identity teaching, people drift back into performance.
Shallow teaching creates shallow confidence.
The Quiet Outcome: Sincere Believers Who Don’t Know Who They Are
When churches remain on milk:
- believers struggle with assurance
- they are easily shaken by hardship
- they depend on emotional experiences
- they confuse identity with behavior
- they don’t know how to rest in Christ
They are sons — but live like spiritual orphans.
They are righteous in Christ — but still relate to God through effort.
They are seated with Christ — but feel stuck on earth.
This isn’t rebellion.
It’s undernourishment.
God’s Goal Was Always Mature Sons
The goal of church was never just attendance.
It was transformation.
Not producing religious activity.
Producing believers who understand:
- Christ’s priesthood
- His finished work
- their righteousness in Him
- their union with Him
God’s desire is not spiritual consumers.
It’s sons and daughters who live from identity.
And identity is shaped by truth.
This Is Not About Legalism — It’s About Seeing Christ Clearly
Growing in Scripture is not striving.
It’s not earning.
It’s discovering.
The deeper believers go into God’s Word, the clearer Christ becomes.
And the clearer Christ becomes, the more rest replaces effort.
Milk keeps people dependent.
Solid food produces confidence.
Personal Responsibility Still Matters
Hebrews places responsibility on the listener:
“You have become dull of hearing.”
Not:
“Your leaders failed you.”
Church culture matters.
But every believer must take ownership of growth.
No one drifts into maturity.
We drift into immaturity.
Understanding Christ requires intentional engagement with His Word.
Final Reflection
Modern churches often succeed at creating welcoming environments.
But Hebrews calls us to grow believers who understand their identity in Christ.
Warmth is good.
But without depth, it produces permanent infants.
God’s desire is not that we stay on milk.
It’s that we grow strong in truth.
Conclusion
The church must become more than a weekly encouragement space.
It must return to being a place where believers:
- learn Scripture deeply
- understand their righteousness in Christ
- grow in discernment
- mature in identity
Because believers who know who they are in Christ live differently.
They rest.
They stand firm.
They walk in confidence.
Not because they try harder — but because they finally understand what Jesus has already finished.
