We often encounter situations where our best efforts to help someone seem to fall short. Despite our good intentions, our care, and our prayers, we can feel powerless to bring about the change we long to see. This sense of inability can be deeply frustrating and disheartening, leaving us to question why our actions were not enough. In these moments, we are invited to look beyond our own strength and recognize the limits of our human power. The struggle itself is a crucial part of our spiritual journey, pointing us toward a deeper need. [01:23]
And when they came to the crowd, a man came up to him and, kneeling before him, said, “Lord, have mercy on my son, for he is an epileptic and he suffers terribly. For often he falls into the fire, and often into the water. And I brought him to your disciples, and they could not heal him.” (Matthew 17:14-16 ESV)
Reflection: Think of a specific relationship or situation where you felt unable to help someone in their struggle. What was it about that circumstance that made you feel your own efforts and resources were insufficient?
The reason for our inability is not a lack of effort or care, but a matter of faith. This is not about the quantity of our faith, as if we must muster up more belief. It is about the quality and focus of our faith—where it is placed. When our faith is fixed on our own abilities, even those given by God, we will inevitably find ourselves powerless. True power is found only when our faith, no matter how small, is anchored in a vibrant relationship with Jesus Christ. [04:19]
Then the disciples came to Jesus privately and said, “Why could we not cast it out?” He said to them, “Because of your little faith. For truly, I say to you, if you have faith like a grain of mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move, and nothing will be impossible for you.” (Matthew 17:19-20 ESV)
Reflection: Where in your life have you been relying more on your own strength or past spiritual authority than on a present, moment-by-moment dependence on Jesus?
There is a profound difference between holding beliefs about God in our minds and truly knowing God in our hearts. Biblical knowledge, or ‘yada’, is deeply relational and experiential. It is possible to spend years in Christian community, studying theology and serving others, and still have a faith that feels hollow because it lacks this personal, experiential knowing. This intimate knowledge of God’s love, grace, and power is what transforms our faith from theory into reality. [16:01]
“I am the good shepherd. I know my own and my own know me, just as the Father knows me and I know the Father; and I lay down my life for the sheep.” (John 10:14-15 ESV)
Reflection: What is one area—such as grace, hope, or God’s love—where you can easily explain the concept but have struggled to feel its reality in your own life?
Prayer is the primary means through which our beliefs about God become a genuine knowledge of Him. It is not a business meeting where we present our plans, but a relational space where we come to be known and loved. In prayer, we allow the light of God’s presence to shine on our false selves—our performing, our hiding—and we experience the truth that we are fully known and fully loved. This is where we are filled with a power that is not our own. [23:36]
“But when you pray, go into your room and shut the door and pray to your Father who is in secret. And your Father who sees in secret will reward you.” (Matthew 6:6 ESV)
Reflection: What is one performance or false identity that you feel you need to put on for others, and how might you intentionally bring that before God in prayer to experience His unconditional love?
Fasting is the practical discipline of self-denial that empowers our faith. It is the voluntary act of giving up our own power, authority, and self-sufficiency so that we can be filled with God’s. By saying “no” to our appetites and comforts, we create space to say “yes” to God’s power and presence. This practice exposes our powerlessness and detaches us from the things of this world, making us conduits of God’s kingdom authority in a way that mere belief cannot. [31:29]
“Then Jesus told his disciples, ‘If anyone would come after me, let him deny himself and take up his cross and follow me.’” (Matthew 16:24 ESV)
Reflection: What is one comfort, habit, or source of self-reliance that God might be inviting you to fast from in order to create more space for His power to work through you?
A man’s frantic threat and a long care relationship frame a searching question: why cannot helpers prevail? That question drives a Gospel episode in which disciples return from the mountaintop into a crisis — a boy broken by seizures and spiritual oppression — and find themselves powerless. The narrative highlights inability three times and locates the problem not in technique or authority bestowed long ago but in the quality of faith. A mustard-seed faith describes a tiny, relational trust fixed on Jesus; it functions not as self-driven effort but as dependence that opens access to God’s transforming presence.
Textual attention to the Gospels shows Jesus’ rebuke ties this weakness to a lack of prayer and fasting. Prayer becomes the medium that turns doctrinal belief into lived knowledge of God, a sustained practice that strips performance and reveals belovedness. Fasting operates as disciplined renunciation: surrendering appetite and control enlarges receptivity to divine power. Together prayer and fasting cultivate the life that bears visible kingdom authority — not by human striving but by emptying for God’s filling.
The account reframes discipleship: power flows from intimacy with the risen Lord, not from professional ministry or religious routine. Knowing God in the heart, not only assenting in the head, produces endurance, clarity, and the ability to help others in ways mere effort cannot. Practical transformation follows habit: consistent withdrawal into prayer and regular fasting break idols of self-sufficiency, expose hidden attachments, and create space for healing and mission. The path toward gospel effectiveness therefore moves through relational knowing, disciplined self-denial, and dependence on the Spirit rather than through better plans, money, or techniques.
A life without prayer is powerless. Maybe that's why there's a gap in your experiences. This is maybe why when you're trying to help others, when we try and go on mission trips, when we try and walk with people and discipleship, why can't we help? Why couldn't I cast it out? Because they know about God and they haven't experienced God yet. Actually, that is the story of the disciples. They don't quite get it yet until Jesus dies and resurrects and appears to them. See, prayerlessness is powerlessness. Prayer is hydration for the marathon of the spiritual life.

#PrayerIsPower
You have to know, not just believe. Belief is just trying to live in the arena of theory. Knowing is vulnerably trusting, experiencing God. It's not enough just to believe facts and theology about God. You have to know God. You have to allow him to love you and see you at exactly who you are, not who you're trying to pretend to be with other people, not the performance you put on when you go to church, to be naked and unashamed as we were in Genesis. And the way you access that, the way we get access to the relationship with God, we all want is actually through prayer.

#KnowGodNotJustBelieve
It's not really instructions for reshaping the landscape of your life. If you just believed hard enough, it's really not about the quantity of faith. It's really not about you and your effort to try. That's not the emphasis of this metaphor of if you just had a faith like a mustard seed. It's a common way of saying the smallest amount of faith accomplishes impossible things. When your faith is fixed on your relationship with the Lord Jesus, there is power. Even if that relationship is infinitely small, it can actually cause great, impossible change.

#SmallFaithBigImpact
The reason they could not cast the demon out, the reason they were unable, the reason they could not help was because they were trying to do so like the rest of the world. They were trying to help out of their own power. Earlier, Jesus gave them the authority to cast out demons. And maybe they were just trusting in this kind of passed on authority rather than a relationship and intimacy with the Lord through prayer and fasting. Their faith was on themselves and their abilities, even empowered abilities, rather than on Jesus.

It's a wonder why we don't experience more of God's love because we haven't tried to walk the ways of Jesus. He believed, Brennan Manning, about God's love. He spoke about it. He counseled other people in it. He studied it. He wrote about it. But it was only when he was stripped of everything, when there was nowhere to hide, where he actually, for the first time, 18 years in trying to follow God, where he experienced the love of God. In prayer, that's when his beliefs about God became knowledge about God.

#BeliefToKnowing
And the reason it all dies is because God wants to really know you and show you that even though all of that died He is still for you. He still loves you. He went to that cross for all of that. That's the pattern of church history actually if you notice it. It comes if you look at church history how does the spirit of God move? How does missions get riled up? It's not through effort. It's not through ingenuity. It's not through money. It is through humble people who do everyday things like pray.

As we pray, you know what happens? The blinding light of God's transfiguration begins to seep into our experience. The Spirit allows our eyes to discover who we truly are. As we fix our hope on God, as we fix our relationship on God, it begins to radically change us, empower us. That is what we're invited to in prayer. That is why these disciples could not help because they were just believing in their head. They were not knowing the Lord through prayer and fasting.

I think many of us, many of you, are probably disenchanted with your Christian life because you have beliefs and ideas but have never known those things. Grace, hope, power. Those are really good ideas on paper. You believe them. But until they become something you know, they're just things on a page. Until they live in your flesh and bones and soul. This is why so many of you still believe in grace and experience in no shame because you haven't known grace. You know about it in your head. You believe it and you haven't felt it.

#ExperienceGrace
That's why so easily circumstances, when they don't go your way, they crush your hope because you believe in hope but you don't know hope. You believe in power through prayer. It sounds great but you don't know it. And many of us, we experience this difficulty, right? We pray really hard and nothing happened and that causes jadedness, frustration, thinking that God is apathetic or indifferent and we remain callous to God. We all have different versions of that. We have theory. We have beliefs about God but we don't live in the knowledge of God.

#BeyondTheories
So yada, knowing someone, is actually deeper than believing. So knowing is deeper according to the Hebrews. Knowing is personal. Until you have a personal experience, it's just a belief that's in the head. And so they use it a little bit oppositely. So I'm going to use it that way in my explanation. So you want to know God. It's when you know God, actually you can truly begin to actually help others. Because who's the one to heal? Not you, not me. You must tap in to the one who actually knows that person, loves that person.

But to be sure, since we have many accounts of Mark's gospel and it's in there, that this was originally part of the story, that Jesus literally said the words, but this kind never comes except by prayer and fasting. And so even though it's not included in our account in Matthew's gospel, for accuracy's sake, in the story itself recorded by Mark, the earlier gospel, we see that it includes this comes by prayer and fasting. I think that's important because it articulates what Jesus means by mustard seed faith. Mustard seed faith is fixed on Jesus through this relational act of prayer and fasting.

#MustardSeedThroughPrayer
But what happens is when you come before the glory of God you know what happens? Something still dies but you can still stand before His presence because what dies is your old self. What dies is the old creation. What dies is all the performing all the faking everything else and that's what we're afraid of. You have to let that self die. All the false views of worth that you dress yourself up with for other people die. The ways that you present your fragile self to prop yourself up before your peers. All the ways that you trick other people or you try and trick yourself all that dies before God's presence.

that word little faith you won't find it anywhere else in the Bible it's interesting little word it's not a total lack of faith it's someone whose beliefs aren't expressed in a way that makes them any different from the life of the unbeliever so they're religious but their life looks no different than a non -Christian maybe we have no power because we're living exactly like non -Christians we just have religion sprinkled on our lives it's a powerless faith because there is no fasting if they just had mustard seed faith they would have been able to help they had no power no authority because they tried to assume it themselves

#NotJustReligion
Prayer is not a business meeting where you're bringing to God your business plan where you're trying to convince Him to do things and invest in things that He otherwise would not. You're not trying to come to God with funding and timelines. I think too many of us come like that. It's a space where sometimes you don't come with anything where you just let this light that could kill everyone in the world where you have now access to it to shine through and it fills all the brokenness of your life and you become someone that God intends you to be.

Do you know the love of God? Or do you just believe it? I'm willing to bet. A majority of you have never experienced. Because I know, Brenna Manning, 18 years, I've had glimpses of this. And I'm still fighting to know the love of God in my own heart. This is the journey of the Christian life. Because it's very easy to believe something in your head. It's totally different to know it. Let me use another analogy. How do you know your spouse loves you?

I think it's about 10 years ago that I was with an elder in our church, caring for a homeless man who had come through our church doors. We got to know his story. We helped him get some temporary housing downtown. We were meeting with him on a semi -regular basis. I was able to give him one of his first Bibles, and we felt like things were really progressing. He wasn't always regular in coming to church, but he would come in and out. Sometimes he would share his struggles, and we'd get a chance to walk with him and pray with him.
