Spiritual Maturity

Every year Mount Everest gets a little taller. The peak is already the highest in the world, at roughly 29,029 feet above sea level. But over millennia, it has risen another 50 to 165 feet—and its elevation continues to grow.

New research suggests that in Everest’s region of the Himalayas, the Earth’s crust is rebounding. This is a phenomenon that occurs when a huge weight that has been pressing down on the surface is removed. The relaxing of the crust in this area started thousands of years ago. With a lightened load, the crust bobbed upward, as a boat might after unloading cargo. The rebound adds about 0.2 to 0.5 millimeter to Everest’s height above sea level each year.

Of course, that doesn’t seem like much. But as one of the co-authors of the study, a geologist, said, “[The growth] seems so insignificant, but then you pile it up over [the years] and you get amazing things happening.”

Possible Preaching Angle:

In the same way, our spiritual growth may seem slow and tiny, but over the years, as the geologist put it, “you get amazing things happening.”

Here’s how Tim Keller used to explain our sin problem:

Imagine your present self looking at your past self, say 10 years ago. Your present self thinks your past self was a fool. Your present self looks back and says, “Back then, I needed guidance I didn't understand. I was so naive. I was so silly. I was immature. I behaved badly.” So, your present self always thinks of your past self as a jerk. Well, the problem is that your future self will think of your present self as a jerk 10 years from now. You'll look back now and say, “Back then, I thought I needed guidance. I thought I understood, but I was such a fool.”

Here's the blunt bad news about our condition: You're always a jerk, but you always think you're just getting over it. We always think that we've just arrived. It's what you thought when you were 15. Then, then you looked back at your 12-year-old self and said, “Now I've arrived. Boy, what a dummy I was when I was 12. I'm ready for the world now.” By the time you're 20, you say that 15-year-old self was so ignorant and flawed and sinful. But you see here’s the point: you’re always ignorant and flawed and sinful, but you continually think you're just getting over it. Sin is deeper in us than we ever imagined.

Do you ever find yourself reminiscing over your favorite childhood toys or memories? A new survey reveals that four in five Americans may be “kidults”—still looking up their childhood favorites for nostalgia.

The poll of 2,000 American Gen Zers and Millennials found that, if given the opportunity, 67 percent would try to buy a replica of something from their childhood and 76 percent feel a sense of nostalgia in the process. This comes as two in three (65%) adults realize they can now buy things for themselves that their parents would never let them have or couldn’t buy for them as a kid.

Commissioned by MGA’s Miniverse, the study found 59 percent of people consider themselves kidults—adults who hold onto their childhood spirit through consumer products like video games, toys, books, movies, fashion, and so on.

Isaac Larian at MGA Entertainment said,

Embracing nostalgia is a big part of being a ‘kidult.’ That feeling gives us the ability to hold onto the imagination and creativity we often associate with childhood. In many ways, holding onto toys and collectibles from our past is both liberating and entertaining, and miniature versions of them makes this experience more accessible. ... (Having) mini toys on display is a constant reminder of being a kid at heart.

Possible Preaching Angle:

It can be enjoyable to relive childish memories and even collect childhood toys. But it can also become a snare for some who never grow to maturity, especially spiritually. Some are content to remain a spiritual babe and never grow to adulthood in their faith (1 Cor. 3:1-3; Heb. 5:12-14).

Sometimes just taking part is what counts. Just ask Belgian shot-put thrower Jolien Boumkwo, who competed in the 100-meter hurdles at the European Athletics Team Championships after her teammates had to withdraw through injury.

After placing seventh in the shot put on Friday, Boumkwo turned her attention to the hurdles at the last minute and duly finished in a time of 32.81 seconds – 19 seconds behind the seventh-placed athlete.

Footage of Boumkwo carefully stepping over each hurdle while the other athletes race away ahead of her has since gone viral on social media. She smiled and laughed throughout before being congratulated by other competitors at the finish line.

Just having an athlete take part in the event earned Belgium two points and saved the team from disqualification. Boumkwo’s efforts weren’t enough to save her country from being relegated to the second division at the meet in Poland, finishing 14th out of 16 countries with 250 points.

Possible Preaching Angle:

Sometimes it is the taking part that really counts. In the church this might mean stepping up to help serve even though it is not our primary spiritual gift. We are part of a team and we all serve for the benefit of the body (1 Cor. 12:1-31) and we should do it with eagerness and joy.

In an issue of Christianity Today, Jen Wilkin writes of an unexpected lesson from Facebook:

Facebook decided to kick off (the new year) with a challenge: Compare your first profile picture to your most recent one to see how hard aging hit you over the past ten years.

I pulled up my first profile picture and stared at it, the air exiting my lungs and an odd numbness seeping up from my toes. Hello, fresh-faced person. I remember you. I remember that shirt, the wallpaper in that kitchen, that haircut. I also remember the night I uploaded you, lightheartedly filling in my Facebook profile with enough information for my identity to be stolen and my house to be robbed.

Imagine if it had been possible to post a picture of your heart (10 years ago), laid next to another (now). A spiritual angiogram, before and after, a trajectory of the growth or decline of wisdom itself. What would it show? Would you want to post it?

This is what I thought as I sat at my computer, contemplating the face of a younger self. I have not stopped thinking about it since. Who says social media can’t make you wise? Facebook invites us to count the lines on our faces, but wisdom reads between those lines.

In CT magazine, singer-songwriter Sandra McCracken writes:

I bought my Santa Cruz acoustic guitar a few years ago at a used music shop in Tennessee. It is sturdy and well made, crafted by hand. A close look at the grain of the wood of my guitar reveals a catalog of past experiences. The instrument’s smoothed surface is a visual timeline, tiny stripes shaped by years of rain and drought. An instrument’s sound tells us something of its origin, whether it is made from new or old or sunken or recycled wood.

A luthier is a craftsperson who builds string instruments the old-fashioned way. Ben Niles’s 2007 documentary Note by Note follows the making of a single Steinway concert piano from the Alaskan forest to the concert hall. Technicians describe their work on a concert grand which, at one stage of the manufacturing process, rests on its side for 12 patient months as the wood of its frame conforms into a piano-shaped curve.

But in real life, transition can foster impatience, like wearing braces or anticipating a wedding after a proposal. During the slow work, we may wonder who we are as we wait for what’s yet to be revealed in us.

But there is a grain written in our design, and we have a skillful designer who first made us and is now forming us into who we are meant to be. During our gradual transformation, we become acquainted with God, who personally and graciously tends to us. He is both the creator and luthier, shaping instruments of his glory. “We are God’s handiwork, created in Christ Jesus to do good works, which God prepared in advance for us to do” (Eph. 2:10).

If, decades ago, we had been there in the forest where my Santa Cruz guitar began, if we had witnessed a tiny Adirondack spruce seed sprouting, vulnerable to every storm and footstep, we would surely doubt that the guitar I now hold in my hands could ever be made. Yet here it is, slowly formed and beautiful. And this gives me hope. God will one day cause us to resonate his love like a well-tuned instrument. Not on the merits of our performance but through God’s own hands, skillfully activating within us the melody of heaven.

Possible Preaching Angle:

To become who God is making us takes time and trust.

Stuart Briscoe preached his first sermon at age 17. He didn’t know much about the topic assigned him by an elder. But he researched the church of Ephesus until he had a pile of notes and three points, as seemed proper for a sermon. Then he stood before the Brethren in a British Gospel Hall and preached.

And preached. And preached. He kept going until he used up more than his allotted time just to reach the end of the first point and still kept going, until finally he looked up from his notes and made a confession.

“I’m terribly sorry,” he said. “I don’t know how to stop.” Briscoe recalled in his memoir that a man from the back shouted out, “Just shut up and sit down.” That might have been the end of his preaching career. But he was invited to preach again the next week. And he continued preaching for seven more decades.

In the process Briscoe became a better preacher, discovered he had a gift, and was encouraged to develop it. He ultimately preached in more than 100 countries around the world and to a growing and multiplying church in America.

When Briscoe died on August 3, 2022, at the age of 91, he was known as a great preacher who spoke with clarity, loved the people he preached to, and a had deep trust in the work of the Holy Spirit.

He once wrote,

My primary concern in preaching is to glorify God through his Son. I’ve worked hard to preach effectively. But I’ve also learned to trust as well. Farmers plow their lands, plant their seed, and then go home to bed, awaiting God’s germinating laws to work. Surgeons only cut; God heals. I must give my full energy to doing my part in the pulpit, but the ultimate success of my preaching rests in God.

How do trees grow the strongest? Surprisingly, too much sunlight and too much easy, fast growth does not produce healthy trees. Most young tree saplings spend their early decades under the shade of their mother’s canopy. Limited sunlight means they grow slowly. Slow growth leads to dense, hard wood.

In contrast, something interesting happens if you plant a tree in an open field: Free from the shade of bigger trees, the sapling gorges on sunlight and grows too fast and too easily. Fast, easy growth leads to soft, airy wood that didn’t have time to densify. And soft, airy wood is a breeding ground for fungus, disease, and ultimately a short life.

As the acclaimed nature writer Peter Wohlleben (author of The Hidden Life of Trees) writes, “A tree that grows quickly rots quickly and therefore never has a chance to grow old.”

In nature, red skin signals that a tomato is ripe. But this is not necessarily true of tomatoes that have been forced to turn red. It is entirely possible, and likely, that we are purchasing and consuming unripe fruit. And there would be little way of knowing it until we take the first bite.

To be fair, part of the reason that growers gas tomatoes with ethylene is because this is what the market demands. As consumers, we want to walk into our local grocery store any time of the day, any day of the week, and pick up a red tomato.

In much the same way, we want the certainty of knowing that the answers to life’s questions are always within reach. But humility teaches us to wait for God for answers. Humility teaches us to let knowledge ripen on the vine.

In the hours immediately before his death, Jesus spends time teaching and praying with his disciples, reminding them that they must abide in him in order to bear fruit. He also promises to send the Helper, or the Holy Spirit, to enable them to learn and grow. Jesus promises them, “I still have many things to say to you, but you cannot bear them now. When the Spirit of truth comes, he will guide you into all truth.”

While Jesus is concerned that his disciples grow in their understanding, he is also comfortable with them not knowing all things—in part because they aren’t ready for more knowledge yet. Jesus is also confident in the Holy Spirit’s ability to take them through the process. But this can only happen as they are connected to him, the Vine.

Proverbs 3 says, “Trust in the Lord with all your heart, and lean not on your own understanding. In all your ways submit to him, and he will make your paths straight.” In God’s wisdom, the very process of learning binds us to him in a way that simply knowing answers cannot. And so he asks you to trust him. He asks you to humble yourself to wait for him.

What’s the name of the tallest mountain in the world? The answer may surprise you. Most people would answer, Mount Everest, but actually it is Mauna Kea, on the island of Hawaii. The inactive volcano is a modest 13,799 feet above sea level, but when measured from the seabed to its summit, it is 33,465 feet high--about three-quarters of a mile taller than Mount Everest.

As far as mountains are concerned, the current convention is that “highest” means measured from sea level to summit; “tallest” means measured from the bottom of the mountain to the top. So, while Mount Everest, at 29,029 feet is the highest mountain in the world, it is not the tallest. Measuring mountains is trickier than it looks. It’s easy enough to see where the top is, but where exactly is the “bottom” of a mountain?

Possible Preaching Angle:

For the Christian, the important thing is not what others see, but the depth of our walk with God. We have a hidden history with God. We must have foundations. It is the hidden prayer life, growth in faith, obedient service, and who you are when no one's looking.

The American Sleep Apnea Association estimates that 22 million of us suffer from some form of sleep apnea. This is a potentially serious disorder in which we repeatedly stop breathing in our sleep. The long-term effects of sleep apnea include high blood pressure, stroke, heart attacks, and is a risk factor for dementia.

CPAP machines are the most widely used device for treating moderate and severe sleep apnea. Through a mask and tube the CPAP machine pumps a continuous stream of oxygenated air allowing you to breathe continuously while you sleep. When you first start using a CPAP machine, the pressure of the rushing air can feel suffocating, but you eventually get used to it.

Possible Preaching Angle:

Two of the most common words translated as "spirit" in the Bible can also be translated "air." In Ephesians 5:18 the present passive imperative verb translated "be filled" tells us that we are commanded to be continuously filled with the Holy Spirit. Unfortunately, Christians suffer from Spirit apnea, a serious disorder in which we repeatedly stop breathing in the life-giving Spirit of God. It's a congenital defect borne out of our spiritual depravity. Spirit apnea, like sleep apnea, can have a grave effect on our hearts, minds, and actions.

Spiritual disciplines are like CPAP machines. They supply us with a continuous flow of God's life-sustaining Spirit. Some of these disciplines include prayer, fasting, Bible reading/meditation, worship, giving, and evangelism. At first these disciplines can seem overwhelming. Over time though, you get used to them and begin to notice the effects.

You can pay extra these days to buy jeans with ready-made holes that make them look old. You can buy spray-on mud so that your 4x4 looks as if it’s been off-road (yes, I’m serious). But there are no easy shortcuts to maturity in the Christian life.

Rory Gallagher was an Irish Blues guitarist who played a battered old Fender Guitar. The paint was stripped off most of it, and it went well with the gritty blues it was used to play. Johnny Marr, of the Smiths, admired Gallagher’s guitar so much that he took his own guitar to the woodwork room at school, trained a blowtorch on it, set the guitar on fire and nearly burned down the school. But to get its battered blues look Gallagher’s guitar travelled a long road of Irish pubs and clubs over many years.

Possible Preaching Angle:

We may think that if we would only read the right books and go to the right conferences, we might quickly become a mature Christian. Not so. We have to go through times of difficulty with the hard knocks of life, to follow the example of our Savior (Heb. 5:8). Moses spent 40 years in the wilderness before he was used by God. Joseph was 13 years in an Egyptian prison. Jesus lived 30 years in peasant obscurity before 3 years that changed the world. What is God taking you through just now? Embrace it. Trust him. Christlikeness is not cheap.

Jess Movold is an elite running coach in New York City. In an article for Runner’s World she discussed the top five principles for successful running. Factors like finishing a marathon, self-discipline, and a workout plan, are essential for guiding runners through a season. But number one on her list to maintaining a long-term relationship with running is finding what really drives you, whether it's a new sense of confidence or getting off medication.

Movold says,

Identifying this unlocks everything that's possible for a runner. That understanding of why you put on your running shoes can be used to hold yourself accountable when you're distracted or discouraged by short-term goals. Whether or not you nail a speed session, those inner passions will persist to drive you.

Possible Preaching Angle:

Scripture describes the Christian life as a race. So, we regularly set goals and we develop structured plans to accomplish these goals. But too often our goals go unrealized and we wonder why. Maybe Movold’s advice applies to spiritual marathons as well. Identifying your motivation unlocks everything that is possible for a Christian. Why do you run?

Pastor David Hansen writes of our need to rely on the Holy Spirit:

I live near a river. Fish live in it, and the willowy river bottom is home to mice and mountain lions. From my kitchen window I watch bald eagles, ospreys, golden eagles, and hawks. These birds of prey ride the wind. It doesn't take much energy on their part. However, when geese fly, they must (expend energy by) flapping their wings, but birds of prey soar by catching currents.

Birds of prey seek thermals; columns of warm air that rise from the earth filled with energy. The birds glide on the heated currents of air. A good thermal can lift them high into the sky without so much as a single flap of their wings. From their higher place they can see more ground and can fly longer and farther, and when the time comes to dive on their prey, they can plummet with great speed.

As I watch these birds, I think of pastoral ministry. I too seek thermals. The Spirit lifts, gives vision, direction, and power. Ministry is riding on the free winds of the Spirit that lift us to heights we cannot climb on our own. We can't stay in the air very long on our own strength, but we can seek thermals. Our soul-wings are made large that we might catch the Spirit.

Possible Preaching Angle:

Although this passage is written to pastors, the illustration itself can easily be directed toward our church members encouraging them to seek the filling of the Holy Spirit through prayer.

Consider this point made by W. E. Adams, C. S. Lewis' spiritual director for a season:

We can advance along the road to perfection only by walking closely with [Jesus]. And as we watch His way of dealing with the countless problems and troubles that beset His life, we achieve wisdom as to how to meet our own. But to walk with Jesus is to walk with a slow, unhurried pace. Hurry is the death of prayer and only impedes and soils our work. It never advances it.

Andrew Wilson writes in an article for Christianity Today:

When you’re sailing, is “being filled with the wind” an experience or a habit? Both. Catching the wind on a sailboat is clearly an experience. I vividly remember that first feeling of being seized and carried forward by a mighty power from elsewhere. But it is also a habit. If you don’t put the sails up, pull the mainsheet fast, or adjust the jib, you won’t go anywhere, even if the wind is blowing powerfully.

Sailing, in that sense, is the art of attentive responsiveness to an external power. You rely entirely on the external power to get you anywhere. Sailors never imagine themselves to be powering the boat by their own strength. But you also have to respond attentively to whatever the wind is doing, which comes through cultivating awareness, skill, and good habits.

Being filled with the Spirit involves the same both-and. We pursue the experience of the Holy Spirit - Paul uses the language of filling and drenching, drinking and pouring. We rely entirely on the Spirit’s immeasurable power, rather than our own strength, to get us anywhere. But we also develop habits. We respond attentively to what he is doing in and through us, a capacity that comes through awareness, skill, and practice. Paul mentions four such habits in subsequent verses: teaching one another, singing, giving thanks, and submitting to one another (Eph. 5:18–21).

In his book, Life in the Presence of God, Kenneth Boa compares a soaring eagle to Christians learning to soar through the power of the Holy Spirit:

God seems to like eagles. Thirty-three Bible verses mention them! Eagles are true flying birds, meaning they get off the ground by flapping, but they soar by thermals. Eagles begin flight training around four months old. But even before that, at about two months, they stand up in the nest and spread their wings when they feel gusts of wind. They're training to know the thermals! Thermals are the columns of air formed as heat rises from the ground. Because heat rises, these air columns push up and up, displacing the cold air around them. By staying in the warmth of the thermal, the birds continue to soar. Eagles become experts in this.

In this magnificent aerodynamic action, gravity isn't deactivated—it's still at work—but the higher principle overcomes gravity. Eagles drop down when they step off a branch. Then, they start flapping like crazy. Once they're in the air, though, their wings don't have to work very hard, and while soaring, they use a small fraction of the effort required to rise. They're almost at rest and can just enjoy the pleasure of flight.

When we first begin following Christ (or practicing a spiritual discipline) we're like eagles spreading our wings. Once we start flapping, though, we lift up. Maybe after a few tries we're back down on the ground. But through repeated practice, we finally soar. Also, in Greek, the Holy Spirit is called pnuema, which means "current of air." Think about what this means for us! We flap and flap, but eventually we catch the current of air, and we soar. This is how the Holy Spirit works with our training. He's not only our coach; he's the power behind everything we do.
