Arrested Development
We would like to say much more about this, but it is difficult to explain, especially since you are spiritually dull and don’t seem to listen. You have been believers so long now that you ought to be teaching others. Instead, you need someone to teach you the basics of God’s word again. You are like babies who need milk and cannot eat solid food. – Hebrews 5:11-12
1 Corinthians 2:14-3:3
But people who aren’t spiritual can’t receive these truths from God’s Spirit. It all sounds foolish to them, and they can’t understand it, for only those who are spiritual can understand what the Spirit means. Those who are spiritual can evaluate all things, but they themselves cannot be evaluated by others. For “Who can know the LORD’s thoughts? Who knows enough to teach him?”
But we understand these things, for we have the mind of Christ.
Dear brothers and sisters, when I was with you, I couldn’t talk to you as I would to spiritual people. I had to talk as though you belonged to this world or as though you were infants in the Christian life. I had to feed you with milk, not with solid food, because you weren’t ready for anything stronger. And you still aren’t ready, for you are still controlled by your sinful nature. You are jealous of one another and quarrel with each other. Doesn’t that prove your sinful nature controls you? Aren’t you living like people of the world?
Developmental Delay in Childhood
Children develop at different rates, and some variation in growth is completely normal. Not every child reaches emotional, cognitive, physical, social, or language milestones at the same pace. Even so, when a child falls notably behind others of the same age in one or more major areas of development, that difference may indicate a developmental delay rather than simple individual variation. In these cases, the gap is significant enough to suggest that the child is not progressing through expected milestones within the typical time frame.
Developmental delays are relatively common in young children and are estimated to affect approximately 10% to 15% of preschoolers. A delay is generally identified when a child does not reach developmental milestones expected for their chronological age. Professionals often evaluate this by comparing the child’s functional age, or current level of performance, with the age at which those abilities would typically be expected.
- Mild: functional age is less than 33% below chronological age
- Moderate: functional age is 34% to 66% below chronological age
- Severe: functional age is more than 66% below chronological age
In cases of developmental arrest, children struggle to acquire new skills, and distressingly, some may even experience regression, losing skills they had previously mastered. This can result in profound, long-term disabilities.
Spiritual Developmental Delay
Spiritual developmental delays are sadly prevalent amongst the children of the King.The Bible shows that people can experience delays in their spiritual growth, much like how some children may not physically or mentally develop as expected. This issue is common among believers. The New Testament, especially in Hebrews and 1 Corinthians, highlights the importance of addressing spiritual immaturity.
Spiritual formation is part of God’s plan for all His children. Being spiritually mature involves more than just knowing things; it means changing our character, improving our ability to tell right from wrong, and getting better at living according to God’s truth. When believers resist this growth, they miss out on the strength, stability, and benefits that come with it.
The main issue is not that some believers grow slowly, but that many are comfortable staying where they are. Some people become so accustomed to complacency that they
remain stuck on basic concepts that feel familiar. The problem is a lack of willingness.
REFLECT & PRAY
Many children of the King struggle with spiritual developmental delay, and some grow resistant to the call to maturity. Instead of pressing forward, they remain confined to spiritual comfort zones and resist the growth the Father longs to see in them.
Father, it is often easy for us to settle into places of comfort and familiarity. Create within us a deeper hunger for Your Word and a stronger desire to grow in wisdom, obedience, and spiritual maturity.
INSIGHT
Paul’s Insight into Spiritual Maturity and Human Nature
Paul’s insight into human nature is remarkably sharp, revealing the complex layers of spiritual life. In his original Greek writing, his precise vocabulary, combined with careful attention to Greek nuances, reveals distinctions often lost in English translation. These distinctions help clarify Paul’s teachings on spiritual immaturity, maturity, and regression.
In this passage, two Greek suffixes are affixed to the ends of four pivotal words. The first suffix, ikos, implies being characterized by. This is a bit tricky to explain. Generally speaking, what they appear to be is what they are. The second suffix, inos, means made of. It denotes whatsomeone or something actually is.
The Greek word that is translated “without the spirit, aren’t spiritual, natural man, soulish, unbeliever” is psuchikos. It is often translated as natural, sensual, or soulish. Psuchikos means characterized by merely soulish reasoning. That is reasoning that is apart from God.
Paul uses the Greek word pneumatikos to refer to those who are “spiritual” or “mature in the faith.” Pneumatikos means to be “characterized by the spirit.” Over time, they have become mature believers who Paul considers spiritual men and women.
Paul speaks of individuals who are “new believers, babies in the faith,” who eventually grow up. Paul characterizes baby believers as “made of flesh,” eventually grow up. Paul characterizes baby believers as “made of flesh,” they are sarkinos,. They are similar to human babies: weak, dependent, sinful, and transitory.
Sadly, many believers refuse to grow up. Despite the time they have had to mature in their faith, they remain spiritually infantile; they act like babies. What might be called the Peter Pan syndrome of the Christian life. Paul identifies this condition with a precise Greek term: sarkikos. The expectation is that believers move beyond the early stage of spiritual infancy, a season when dependence on the flesh is understandable, and grow into genuine maturity. But some never make that transition.
Their experience is designated as Arrested Spiritual Development. They are stuck at a stage they were meant to pass through. They are still acting like newborns when they should long since have grown up. Rather than living as pneumatikos, those characterized by the Spirit, they remain sarkikos, characterized by the flesh, conducting themselves no differently than the world around them
As the ESV Study Bible notes, “Although the Corinthians are Christians indwelt by the Spirit, their divisive behavior shows that they are acting like the unbelieving world around them.”
Four Spiritual Categories
Paul outlines four broad categories of people.
- First, there are soulish people, or unbelievers, who live apart from the life of the Spirit.
- Second, there are the spiritually mature, those who are growing in Christ and whose lives are increasingly shaped by the Spirit.
- Third, there are baby Christians, newly born into the family of God and still in the early stages of growth.
- Fourth, there are fleshly or carnal Christians, believers who have had ample time to mature but continue to behave like spiritual infants.
Understanding these distinctions is crucial to avoid confusion. Immaturity arises from different causes, and believers are at various stages. Spiritual infancy may be appropriate for a new believer, persistent immaturity in an older believer indicates a failure to thrive.
The Danger of Spiritual Regression
Spiritual immaturity isn’t the only risk; regression is also possible. Someone may begin to grow toward maturity but then revert. This is what occurred with the Jews for Jesus in Hebrews 5, as they had become “dull of hearing.”
In Hebrews 5:11-12:
“There is much more we would like to say about this, but it is difficult to explain, especially since you are spiritually dull and don’t seem to listen. You have been believers so long now that you ought to be teaching others. Instead, you need someone to teach you the basics of God’s word again. You are like babies who need milk and cannot eat solid food.”
This rebuke is striking. These believers had been in the faith long enough to instruct others. Instead, they had regressed to a point where they needed to revisit basic biblical truths. Their issue was not a shortage of opportunities but a failure to respond. Spiritual decline seldom occurs abruptly; it usually starts gradually through neglect, apathy, and a decreasing focus on God’s Word.
The Meaning of Dullness in Hebrews
The Greek term nothros, often translated as “dull of hearing” or “spiritually dull,’ signifies being “slow to learn, sluggish in comprehension, and hesitant to respond.” It conveys a sense of mental and spiritual sluggishness, where an individual becomes unresponsive to truth. This word may describe someone who is “slow-minded, forgetful, or spiritually insensitive.” It also implies “feeling weighed down or unresponsive, contrasting with alertness, eagerness, or sharpness.”
Maturity Requires Intentional Pursuit
From the Father’s perspective, growing older is not the same as growing up. Genuine growth results from intentionally seeking the Father and a willingness to follow His directives. This involves more than casual Bible reading; it calls for diligent study, understanding, and sound judgment.
In 2 Timothy 2:15, the apostle Paul writes, “Work hard so you can present yourself to God and receive his approval. Be a good worker, one who does not need to be ashamed and who correctly explains the word of truth.”
Arrested Spiritual Development
Many children of the King experience Arrested Spiritual Development. Many neglect God’s call to spiritual maturity, settling instead for a superficial faith experience. Rather than seeking wisdom, depth, and obedience, they cling to immature patterns of thought and behavior. True spiritual development involves a deliberate effort to abandon childish ways and habits (1 Corinthians 13:8-12). Genuine maturity is measured not just by knowledge but by how faithfully that knowledge is lived out.
From Milk to Solid Food
Stunted spiritual growth often results from inadequate nourishment. The Bible compares the Word of God to various foods: milk, solid food, and meat. While foundational teachings, like milk, are vital for newcomers, growth requires advancing to more profound and complex understanding, symbolized by solid food and meat.
Just as infants naturally progress from milk to solid foods as they grow physically, children of the King are called to move beyond basic teachings to develop greater insight and discernment. Sadly, many remain on a milk diet for too long, hindering their growth.
The Father longs for all His children to mature into stable, effective believers. This maturity depends on consistent spiritual nourishment, discipline, and a willingness to explore the depths of God’s Word.
Spiritual maturity requires intentional growth, not passive existence.
