“Trust in the Lord with all your heart, and do not lean on your own understanding.” — Proverbs 3:5
While it is presented as a command, it often feels more like a triple-dog dare.
Trust in the Lord.
Not partially.
Not occasionally.
Not when circumstances make sense.
Trust Him with all your heart.
If we’re honest, that can feel impossible at times.
Most of us don’t struggle with believing God exists. We don’t struggle with acknowledging that He is wise, powerful, or good. We nod in agreement when Scripture tells us that God can be trusted.
The challenge comes when trust is called upon to act.
The challenge comes when we are asked to climb into the wheelbarrow.
Seeing Is Believing—Until It Isn’t
Charles Blondin was the world-famous tightrope walker who became the first person to cross Niagara Falls on a tightrope.
But crossing once wasn’t enough.
He crossed repeatedly.
He crossed blindfolded.
He crossed carrying objects.
He even stopped midway to cook an omelet.
According to the famous story, after successfully pushing an empty wheelbarrow across the falls, he turned to the crowd and asked:
“Who wants to get in?”
No one volunteered.
Why?
Because intellectual assent cannot hide true belief.
Everyone watching believed Blondin could cross.
No one trusted him enough to climb into the wheelbarrow.
The story paints a perfect picture of our challenge with Proverbs 3:5.
Our minds tell us we shouldn’t have an issue with this command, but our hearts drag their little feet.
We believe God is trustworthy.
We just aren’t always eager to trust Him completely.
The Ultimate Dare
Proverbs 3:5 doesn’t simply tell us to trust God.
It tells us to trust Him with all our heart.
That’s what makes the verse so challenging.
Many of us are willing to trust God with eternal matters while reserving control over everyday matters.
We trust Him with heaven.
We struggle to trust Him with our finances.
We trust Him with salvation.
We struggle to trust Him with uncertainty.
We trust Him with the future.
We struggle to trust Him with today.
Yet Solomon leaves no room for partial trust.
The command is comprehensive.
Trust Him with all your heart.
And then Solomon immediately adds:
“Do not lean on your own understanding.”
That’s where the real battle begins.
Our Understanding Is Severely Overrated
Most of us don’t think we’re leaning on our own understanding.
Until life doesn’t go according to plan.
Then we discover how much confidence we’ve placed in ourselves.
We evaluate circumstances.
We form conclusions.
We determine what should happen.
We decide what God ought to do.
Then when events unfold differently, frustration sets in.
Not because God has failed.
But because our understanding has become the standard by which we judge Him.
As Jon Bloom writes:
“It is not the one who trusts in the Lord that is irrational, but the one who leans on his or her own understanding.”
That observation is uncomfortable.
We tend to assume that trusting ourselves is the reasonable choice.
Scripture says the opposite.
In fact, many of the things that produce anxiety, fear, anger, and disappointment are rooted in the assumption that our perspective is sufficient.
It isn’t.
Our understanding is useful.
But it is also limited.
Painfully limited.
The longer we live, the more opportunities we have to discover just how little we actually know.
From Suspicion to Surrender
Trust often reveals itself in unexpected places.
A few years ago, after purchasing a vehicle for my son, I needed to have it transported from Illinois to Arizona.
Simple enough.
At least that’s what I thought.
After researching companies and comparing quotes, I settled on one that seemed trustworthy.
Then things became complicated.
The company turned out to be a broker.
The broker hired another company.
That company found another driver.
Then the driver who picked up the vehicle wasn’t necessarily the driver who would deliver it.
At some point, I realized I had essentially handed a vehicle to a man named Andrew, who was working for a driver, who was working for a driver, who was working for a transportation company.
If this sounds suspicious, it felt suspicious.
I could already imagine explaining to law enforcement that I had voluntarily handed over a car to a stranger and watched him drive away.
Thankfully, everything worked perfectly.
The car arrived early and in excellent condition.
But God used the experience to remind me of something important.
He wasn’t trying to move me further along the spectrum toward trusting people.
He was moving me toward understanding whom I should trust regardless of the circumstances or outcomes.
That’s often how trust works.
God doesn’t always remove uncertainty.
He uses uncertainty to reveal where our confidence actually rests.
Fear Reveals What We Trust
One of the clearest indicators of trust is fear.
What we fear most often reveals what we trust least.
This is why the Bible repeatedly connects the fear of the Lord with confidence.
At first glance, that seems contradictory.
But it isn’t.
As John Piper writes:
“Fear of God will drive us to hope in God’s steadfast love, and not ourselves.”
The fear of the Lord doesn’t increase anxiety.
It reorders it.
The fear of God shrinks lesser fears because it enlarges our vision of God.
When God becomes small, everything else becomes large.
Failure becomes large.
People become large.
Financial concerns become large.
The future becomes large.
But when God occupies His rightful place, lesser fears begin shrinking into their proper perspective.
As John MacArthur explains:
“To fear God is to live in the reality of His holiness, His sovereignty, and His judgment of sin. It is to love God, respect Him, reverence Him, adore Him, hold Him in awe, and worship Him.”
That’s not terror.
That’s trust-producing awe.
And Scripture attaches remarkable promises to it.
The Lord confides in those who fear Him.
The angel of the Lord encamps around those who fear Him.
His lovingkindness rests upon those who fear Him.
Fearing God rightly becomes one of the greatest pathways to trusting Him deeply.
Fear Missing Out on the Right Things
One of the most common fears today is the fear of missing out.
We fear missing experiences.
Missing opportunities.
Missing success.
Missing recognition.
Missing whatever everyone else appears to be enjoying.
But perhaps we should ask a different question.
What is worth finishing?
I have spent much of my life being an incredibly good starter.
Ideas.
Projects.
Plans.
Goals.
Big dreams tend to attract attention.
The problem is that attention is limited.
Within the last year, I lost both my mother and my father-in-law.
What they left unfinished became a powerful reminder of what actually matters.
The house projects.
The paperwork.
The tasks.
None of those things compared to hearing family members express gratitude, admiration, and love for lives that had been invested in the right things.
Suddenly, the question wasn’t:
What should I start?
The question became:
What is worth finishing?
Jesus answers that question clearly:
“Seek first the kingdom of God and His righteousness…” (Matthew 6:33)
The most important thing should receive our full attention.
The most important thing should be first.
The fear of missing out often distracts us from what matters most.
Trust keeps us focused on the things that will still matter when everything else fades.
When Doubt Shows Up
Even mature believers experience doubt.
John the Baptist doubted.
Thomas doubted.
The father who brought his demon-possessed son to Jesus doubted.
The issue isn’t whether doubt appears.
The issue is how we respond when it does.
Alisa Childers offers a helpful reminder:
“Doubt isn’t the opposite of faith. Unbelief is the opposite of faith.”
That’s important.
Because many Christians assume that doubt itself is failure.
It isn’t.
Doubt can become an invitation.
An invitation to seek.
To wrestle.
To grow.
To deepen your faith.
The father in Mark 9 gives us perhaps the most honest prayer in Scripture:
“I believe; help my unbelief.”
That’s what trust often sounds like.
Not certainty.
Dependence.
Not confidence in ourselves.
Confidence in God.
Tim Keller offers another helpful principle:
“Doubt your doubts.”
Before automatically accepting every fear, every uncertainty, every skeptical thought, ask whether it deserves your trust.
Because every doubt rests upon some competing belief.
And many of those competing beliefs are far less reliable than God’s promises.
Lean Toward God
One of the most helpful observations I’ve encountered about doubt is that it is directional.
We can doubt toward God.
Or we can doubt away from Him.
When questions arise, the goal is not to retreat.
The goal is to lean toward God.
Ask for reassurance.
Ask for wisdom.
Ask for understanding.
Ask for evidence if necessary.
But keep moving toward Him.
Many people allow uncertainty to become an excuse for apathy.
Instead, uncertainty should become an invitation to pursue.
To study.
To pray.
To wrestle.
To seek.
The goal is not to eliminate every question.
The goal is to deepen trust.
Get in the Wheelbarrow
At the end of the day, trust is not merely agreeing with God’s promises.
It is acting upon them.
The crowd watching Blondin believed.
They simply weren’t willing to climb into the wheelbarrow.
Many of us treat Proverbs 3:5 the same way.
We admire it.
We agree with it.
We quote it.
But then life becomes uncertain.
And suddenly trusting God feels far more dangerous than leaning on our own understanding.
Yet Scripture insists that the opposite is true.
Our understanding is limited.
God’s understanding is not.
Our vision is partial.
His vision is complete.
Our plans are fragile.
His purposes stand forever.
The ultimate dare of Proverbs 3:5 is not simply to believe that God can be trusted.
It is to trust Him more than we trust ourselves.
And when we do, we discover something remarkable.
The safest place in the world is not in control of our own lives.
The safest place is in the hands of the God who has always been worthy of our trust.
