Key Texts: Jeremiah 17:9; Genesis 3:1-7; Romans 1:21-25; Ephesians 2:1-3
Goal: Create space for honest acknowledgment of our condition without triggering shame or defensiveness.
Open with a common experience:
"Have you ever been completely convinced you were right—and later discovered you were completely wrong?
Not a small mistake. A situation where you were certain of your perspective, confident in your judgment, maybe even righteous in your anger—and then new information surfaced, or time passed, and you realized you had been blind to something obvious. Your own heart had deceived you.
Or maybe you've had the experience of doing something you knew was wrong, something you'd told yourself you'd never do—and afterward wondering, 'Who was that? Where did that come from?'
These moments are unsettling because they reveal something we'd rather not face: we are not as self-aware, not as in control, not as good as we like to believe.
Then read the anchor text slowly:
"The heart is deceitful above all things, and desperately sick; who can understand it?" (Jeremiah 17:9)
"This is God's assessment of the human heart. Not 'occasionally misleading.' Not 'slightly biased.' Deceitful above all things. We don't even have full access to our own depths. The heart hides from itself.
Before we can appreciate what the Spirit offers to do in us, we have to be honest about why we need it. Today we're looking at what Willard calls 'radical evil'—the depth of what has gone wrong in the human soul."
Goal: Diagnose the root of human fallenness (not just symptoms), establish why self-help fails, and help participants examine their own hearts with honesty rather than defensiveness.
Before launching into the teaching and questions, acknowledge the weight of the material:
"This is heavy content. The goal today isn't to wallow in guilt or leave feeling terrible about ourselves. The goal is honest diagnosis—the kind a doctor gives before treatment. A good diagnosis isn't an attack; it's the necessary first step toward healing. So let's approach these questions with honesty rather than defensiveness, and with hope rather than despair."
"Last week we mapped the six dimensions of the self. Today we have to face what's happened to all of them. But we're not starting with symptoms—we're going to the root.
What is the fundamental problem with human beings?
We often answer in terms of behavior: we lie, we lust, we steal, we gossip. Or in terms of feelings: we're anxious, angry, envious. Or in terms of broken relationships: we wound each other, we withdraw, we exploit.
All of that is true. But those are symptoms. Willard presses deeper: what's the disease underneath?
The answer is found in Genesis 3. Look at how the serpent frames the temptation:
'For God knows that when you eat of it your eyes will be opened, and you will be like God, knowing good and evil.' (Genesis 3:5)
You will be like God. That's the temptation at the root of all temptation: to be your own god. To place yourself at the center of your universe. To make yourself the final authority on what is true, what is good, what is right for you.
This is what Willard calls 'the primary mistake': the human self, stepping into the place that belongs to God alone, trying to run the show on its own.
And notice—this isn't just about behavior. Eve saw that the tree was good for food (body), a delight to the eyes (feelings), and desired to make one wise (mind). The temptation engages multiple dimensions. But the root decision happens in the will: 'I will be my own god. I will decide for myself.'
Every sin since has been a repetition of this fundamental move.
"Paul gives us the most systematic picture of how this plays out in Romans 1:
'For although they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking, and their foolish hearts were darkened. Claiming to be wise, they became fools, and exchanged the glory of the immortal God for images resembling mortal man and birds and animals and creeping things... They exchanged the truth about God for a lie and worshiped and served the creature rather than the Creator.' (Romans 1:21-25)
Watch the progression. It's a cascade of ruin across the dimensions:
This is the ruined soul. Every dimension—will, mind, feelings, body, relationships—has been bent away from God and toward the self. And it all started with one decision: I will be my own god.
Paul summarizes the result in Ephesians:
'And you were dead in the trespasses and sins in which you once walked, following the course of this world, following the prince of the power of the air, the spirit that is now at work in the sons of disobedience—among whom we all once lived in the passions of our body, carrying out the desires of the body and the mind, and were by nature children of wrath, like the rest of mankind.' (Ephesians 2:1-3)
Dead. Not injured, not weakened—dead. Following the world's course. Enslaved to bodily passions. Carrying out desires we didn't even choose. Children of wrath by nature—this has become what we are, not just what we do.
"Here's where this diagnosis becomes practical.
If the problem were just bad behavior, the solution would be trying harder. If the problem were just wrong thinking, the solution would be better education. If the problem were just poor habits, the solution would be new techniques.
But if the problem is a deceitful heart that doesn't even know its own depths—a heart that has made itself god and organized everything around that false center—then no amount of self-effort can fix it. The very self that would do the fixing is the problem.
This is why Jeremiah follows his diagnosis with a question: 'Who can understand it?' We can't fully see our own ruin. We're like a patient trying to perform surgery on their own brain.
Willard puts it starkly: 'The resources for transformation are not found in the self that needs to be transformed.'
This is not pessimism—it's realism that makes room for hope. If we could fix ourselves, we wouldn't need a Savior. We need rescue. We need power from outside ourselves. We need the Spirit to do what we cannot do.
And that's exactly what's offered. But before we get to the solution, we have to let the diagnosis land. The temptation is always to rush past our ruin toward the remedy. But cheap grace produces shallow transformation. We need to feel the weight of what's wrong before we can appreciate what's being offered.
Close the Explore & Engage section by returning to the thesis:
"Remember our thesis: We fail when we doubt real change is possible or when we simply don't take it seriously.
Today we've seen why real change is necessary. Every dimension of the self has been disordered by the fundamental decision to be our own god. The heart is deceitful above all things. We were dead in our trespasses.
But remember the rest of the thesis: To enter this journey, we must understand the dimensions of our inner being and then meet the Spirit in His power.
Diagnosis is not the end. It's the necessary preparation for what comes next. Next week we'll look at what Willard calls 'radical goodness'—the path of self-denial that opens us to the Spirit's transforming work. But this week, we sit with the honest recognition: we cannot fix ourselves. And that's the beginning of hope."
"This week, we're going to examine what competes with God for the center of our lives.
Each day, notice what you think about most when your mind is free. Notice what you're most afraid of losing. Notice what makes you most anxious, most defensive, most driven.
Then ask these diagnostic questions:
These aren't necessarily bad things. But when they move to the center—when they become what we functionally worship—they disorder everything else.
Write down what you discover. Don't try to fix it yet. Just notice what has quietly taken God's place.
Bring your reflections next week as we explore the path out of self-worship."
"This week, we're going to practice inviting God into the parts of our heart we usually hide—even from ourselves.
Each day, take five minutes to pray this simple prayer:
'Search me, O God, and know my heart; try me and know my anxious thoughts. See if there be any grievous way in me, and lead me in the way everlasting.' (Psalm 139:23-24)
Then sit in silence. Don't rush to fill the space. Let God search.
If something surfaces—a memory, a pattern, a motive, a wound—don't defend yourself. Don't immediately try to fix it. Just acknowledge it to God: 'Yes, Lord. This is here. This is part of what needs healing.'
This is the prayer of someone who knows their heart is deceitful and needs an outside perspective. We're inviting God to show us what we cannot see on our own.
Journal briefly afterward about what, if anything, surfaced. Bring your reflections next week as we explore the path out of self-worship and into freedom."
