The King and the Kid

Familiarity, Unbelief, and the Faith the Western Church Has Lost

They Had Done This Before

In Matthew 17, a father kneels before Jesus and begs for his son. His boy has been tormented since childhood, thrown into fire and water by a demon that has controlled him for years. He brought the boy to the disciples first. They tried. And failed. The crowd looked on as Jesus arrived.

Before we understand what went wrong here we need to understand what went right everywhere else. Jesus had given authority to the disciples over unclean spirits. They had used it. Luke 10:17 tells us they returned with joy, saying, “Lord, even the demons submit to us in your name.” This was not theoretical. It was field-tested and proven. There was a track record.

So when this desperate father brings his convulsing, demon-tormented son to these same disciples and nothing happens, the question is not if they had authority. They did. The question is why the authority didn’t work. And Jesus, as He very often does, diagnoses the problem from the inside out.

“O faithless and perverse generation, how long shall I be with you? How long shall I suffer you?” (Matthew 17:17)

He does not say the demon was too powerful. Or they forgot the formula. He says they are faithless. That word matters. It is the diagnosis. Everything he says next flows from it.

The Reading the Church Has Settled For

Most believers know one thing about this passage. Some demons require fasting and prayer to defeat. This has launched an entire cottage industry of deliverance and spiritual warfare teaching, all built around this interpretation. Demons get ranked. They get categorized into tiered difficulty. And the church learns the first question is: What kind of demon is this? What method do I need to defeat it? Am I even capable of defeating it?

This reading feels sophisticated. It sounds like insider knowledge. But it creates a framework Jesus never taught and ignores the one He actually gave in the passage itself.

Read the text again, carefully. In Matthew 17:20, Jesus says:

“Because of your unbelief; for assuredly, I say to you, if you have faith as a mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move; and nothing will be impossible for you. However, this kind does not go out except by prayer and fasting.”

“This kind.” The question is what “this kind” refers to. Grammatically and contextually, Jesus has just been talking about one thing. Unbelief. He identified the problem as unbelief in verse 17. He restated it in verse 20. Then immediately, in the next breath, He says “this kind does not go out except by prayer and fasting.”

The most natural reading of the text is that Jesus is talking about a kind of unbelief. Not that he’s creating a demon-ranking framework He never addresses again. This kind of unbelief is stubborn, deep-rooted, we’ve-done-this-before, kind of unbelief that had taken hold and wouldn’t yield to casual spiritual effort or formula.

Power and Authority: These Are Not the Same

Power is what you are given. Authority is what you actually operate in. The disciples had been given power. Jesus Himself conferred it. But authority is not a static possession. It flows through the inner life of the one exercising it. And their inner life had drifted. This distinction matters more than most teaching on spiritual warfare ever acknowledges.

A demon is never confused about authority. It responds to what is behind a command, not just the words. When the disciples stood before the boy and issued their instruction, the demon didn’t hear men operating in genuine, unshakeable trust. It heard the voice of uncertainty. So it stayed. Unmoved.

We see this confirmed elsewhere in the book of Acts. The seven sons of Sceva tried to invoke the name of Jesus over a demon, without actual authority to do so. The demon’s response was blunt: “Jesus I know, and Paul I know, but who are you?”

The authority is not in the name as a formula. It lives in the relationship and faith behind the name. The disciples had the relationship. But at that moment, they lost the faith that gave it operational weight.

You cannot project outward what you have not cultivated inward. The command is only as effective as the conviction behind it.

A Lesson From Home

“And He did not do many miracles there because of their unbelief” (Matthew 13:58).

When Jesus returned to His hometown, Matthew tells us He did not perform many miracles due to their unbelief. Jesus did not lose power at the city limits. What He lost was an invitation.

Faith is what reaches toward God and asks. Unbelief asks nothing, or asks with so little conviction it barely registers as a request. And God, who will not force Himself on anyone, responds to what is actually extended toward Him.

This account is usually read as evidence that unbelief neutralizes divine power. That human skepticism can tie the hands of God. But this misrepresents both the text and the nature of God.

The people of Nazareth had all heard the stories. Reports of Jesus’ miraculous works in Capernaum and Jerusalem, and across Galilee, had surely reached their village. But they could not reconcile those stories with the man they built in their mind. They had watched Him grow from a boy; knew His mother and His brothers. They had likely all done some trade with Joseph. They had already decided who He was. Familiarity had done its quiet, devastating work.

They could only see a kid where a King stood. They had no capacity to see the King that had always been in the kid.

He did not become the King when the miracles began. He was always the King. In the carpenter’s shop. Working with His hands. Growing in their midst. The King was never absent. It was their ability to see Him that was.

Here is what makes this particularly tragic. The familiarity was a gift and they made it a prison. The people of Capernaum would have given all they had for the access Nazareth squandered. They grew up next to the Son of God. They ate with Him. Worked near Him. Watched Him grow into a man.

All that proximity made them less likely to believe. Proximity without humility produces assumption. And assumption closes the very door faith is meant to open.

James makes it very clear: “You have not because you ask not.” And you will not ask from someone you already decided cannot give what you need.

The Cost of Belief

There is another aspect here that rarely gets named. Familiarity not only creates doubt. It also comes with a cost.

Following a stranger who performs miracles costs you very little. There is no prior relationship to negotiate, no social standing to risk, no history that is contradicted by this new identity. In this case belief is essentially free.

But to declare the man who grew up next door is the Messiah? That costs something very real. It forces you to reshape your entire framework that defines who He is. Your neighbors will all have opinions. It means any trade or interaction between your family and theirs now comes with a theological commitment. The cost comes due right away and can’t be ignored.

Celebrity Christianity is as comfortable as it is dangerous. We can follow our favorite preachers and teachers from a safe distance. We never have to see their ordinary moments or failures. The distance allows us to project onto them whatever we need from them.

And if the theology gets uncomfortable or demands too much, we can unsubscribe and move on to the next big thing. The one whose podcast asks less from us. We have no community to be answerable to, no elder who knows our actual life, no neighbor to hold us to what we said last Sunday.

Consider how differently we treat a celebrity donor and a neighbor asking for the same help. A stranger donates a million dollars and we celebrate without question. Our neighbor tries to raise a thousand dollars and we are suddenly suspicious of his motives. Why? Because we know him. We’ve seen his inconsistencies. Watched him fail.

We put more scrutiny on those closer to us. Familiarity doesn’t just produce doubt. It produces a more demanding standard of proof, a shifting standard to fit our needs.

Nazareth held Jesus to a standard they would never hold a neighbor to. And the cost to believe raised the bar too high. The social reorganization, the admission of misjudging Him, the life-reorientation that following a Messiah demands; it was all too much.

An Unbelief That Resists Easy Answers

If the problem is unbelief, the next obvious question is why some unbelief requires prayer and fasting to overcome. Isn’t unbelief just unbelief?

The father in our story provides us some insight. Jesus tells the man all things are possible to one who believes. And we see one of the most honest answers in all the Gospels when the father cries:

“Lord, I believe; help my unbelief!” (Mark 9:24)

This man both believes and doesn’t believe. He is holding faith and doubt in the same moment. Both things can be true, and are true. He is not a cynic. He is not an atheist. He’s just a man whose faith is real but insufficient. Mixed with grief, desperation, and failed expectations.

This is where most of us live. We believe, and we don’t. We pray, and we hedge. We ask God, and we simultaneously construct our backup plans. It’s not the bold, simple, childlike mountain-moving faith.

Adult faith. Analyzed, protected against disappointment.

Jesus says we must receive the kingdom as a little child if we hope to enter. Children believe what they are told. They don’t require proof before trusting a promise. Adults analyze. We categorize the problem before we bring it to God.

We assess our odds. We look for the right spiritual technique for this category of obstacle. And in doing all this careful planning and reasoning, we miss the one thing that actually works. Simple, undivided trust.

“This kind” of unbelief, the deep-rooted, experience-informed, self-protecting, analysis-heavy unbelief that even committed disciples develop; it does not yield to casual effort. It requires something more serious.

It requires prayer. And it requires fasting.

What Prayer and Fasting Do

If prayer and fasting are prescribed for stubborn unbelief, not stubborn demons, we need to reassess our understanding of them. They are not spiritual power tools. Not techniques to wield supernatural force or weaken demonic resistance.

They are disciplines. And rather than affect outwardly, they affect inwardly. They do something to us.

Fasting strips the body of its assumed authority. When you fast you become acutely aware you are not self-sufficient. Each hunger pang is a reminder that your body cannot sustain itself. That you depend on something outside of yourself for life.

That acute awareness breaks down the quiet arrogance of self-reliance built up by adult life. It cuts through the noise of your own plans and preferences. It leaves you in a posture of dependence. And this is by design.

Prayer, done seriously, and not as a quick ritual does the same thing, but to the will. Extended, honest prayer forces you to bring everything before God. Your fears. Your doubts. Your analysis. Your backup plans.

And then honest prayer forces you to release them.

It is the sustained act of choosing dependence over control. It is the practice of becoming, however briefly, like a child who trusts.

Together, prayer and fasting cultivate faith that does not arise naturally. They don’t change the spiritual landscape around you. They change the spiritual landscape inside you. They rebuild the inner life that authority flows through. They recover childlike simplicity. This is what the disciples had lost somewhere between their successful missions and this moment of failure.

This is why prayer and fasting are the prescription for stubborn unbelief. Not because they impress God. Not because they exhaust the enemy. But because they hollow out the self. They create the interior conditions where simple faith can actually thrive.

The Church at the Base of the Mountain

A demon-hierarchy interpretation is more comfortable than a faith interpretation. If the problem is categories of powerful demons, then the failure is external. We need better technique, stronger prayer warriors, or more experienced spiritual authority. It’s not our problem. The issue is out there and the solution clearly is more firepower.

But if Jesus is right, then the problem lies inside us. The church’s problem is not a demon problem. It’s a faith problem. We have built impressive religious machinery that runs with little need of God.

Our programs are managed. The outcomes are optimized. And somewhere in all of that competent management, we developed the same unbelief the disciples had at the base of that mountain. It’s functional. It’s experienced. It’s credentials. And it’s hollow.

We have built a religion of comfortable distance. We follow from far enough away our belief costs us very little. We celebrate what God does in the other ministries and churches we observe, but don’t really know. Then when the need is right in front of us, the person at the bottom of the mountain with a desperate need, we learn we had a spectator faith, not operating faith.

Much like Nazareth we developed familiarity with Jesus without ever getting too close to Him. We know the stories. We sing the songs. We know what He’s done elsewhere. But familiarity with reports of God’s power is not the same as activated faith. When He stands before us in a moment that requires real trust we see what we’ve always seen; not the King, but our manageable idea of Him.

The disciples standing at the base of the mountain certainly appeared capable. They had the credentials and the track record. They had the authority of Jesus behind them.

And they couldn’t do a thing.

Authority without faith is an empty title. You can’t project out what you have not cultivated within. And what they had stopped cultivating, what the Western church all too often has stopped cultivating, is simple, childlike trust that can move a mountain.

The Honest Cry that Leads Somewhere

The father’s cry is the beginning, not the end. “Lord, I believe; help my unbelief” is not failure. It is an honest statement and is the kind of honesty that precedes breakthrough. He was not pretending to possess faith he didn’t have. He presented his true condition to the only One who could change it.

And his son was healed.

This is where the church should begin. Not with more spiritual warfare training. Not with better discernment of demonic rankings. Not with celebrity faith borrowed from someone else’s testimony. With the same honest cry: Lord, we believe. Help our unbelief!

And then pray, seriously, not as a performance. And fast. Strip away all self-sufficiency. Get rid of the analysis and the backup plans. Continue to do it until the inner life changes. Do it until sophisticated adult doubt gives way to childlike simplicity. Do it until familiarity with God stops being a substitute for actual dependence on Him. Do it until you remember He does the work, not you.

The demon at the base of the mountain was never the main event. What was happening inside the disciples was. And it’s the same thing happening inside of us.

This kind does not go out except by prayer and fasting.

Not because the enemy is too strong.

Because we have not become weak enough to rely on God’s strength.
