As a pastor teaching a 12th-grade Bible class at a local Christian school, I guide students through the core theological topics of the Christian faith. Rather than skimming the surface, we dive deeply into a few key subjects, sparking rich discussions among teenagers who are beginning to grapple with their beliefs.
In our unit on sin and anthropology, I open with a provocative question: “Which is stronger—man or sin?”
The room falls silent. Eyes squint, pencils tap, and nervous glances are exchanged. Some students hesitantly raise their hands, others fidget. Remarkably, every student answers correctly: sin is stronger than man. Every time. Some point out that if man were stronger, Jesus’ death would have been unnecessary. Others cite humanity’s moral decline, arguing that history shows no progress in overcoming sin. A few draw from personal experience, noting that if man could conquer sin, we would have stopped sinning long ago.
The question seems daunting, but the answer is intuitive. The real tension lies not in the answer itself but in its implications. If sin is stronger than man, what does this mean for our daily Christian life? For our fight against sin? For repentance? For our choice to accept Jesus as Savior? Ultimately, the question becomes: If sin overpowers man, do we truly have free will?
The Theological Divide
This tension—between knowing sin’s dominance theologically and assuming personal control functionally—is striking. The debate over free will is ancient, stretching back to humanity’s earliest encounters with sin. It reached a peak during the Protestant Reformation, particularly in Martin Luther’s 1525 work, The Bondage of the Will, a response to Desiderius Erasmus’ The Freedom of the Will. Luther argued, based on a plain reading of Scripture, that humanity’s will is bound, not free. He boldly declared, “Free will is a downright lie.”1 It’s a fiction.
What Free Will Is Not
When Luther denies free will, he is not saying humans lack a will entirely. A common misconception is that a bound will means we cannot choose anything—whether it’s the color of our shirt, whether to carry an umbrella, whom to marry, or which career to pursue. Luther clarifies that humans have freedom in matters “below us.” In temporal, earthly affairs, we can choose according to our desires: what to eat, which team to support, or where to park. God, in creating us as His image-bearers, grants us “natural ability” to make decisions within the bounds of our human nature. As Luther writes, “I know that ‘free will’ can do some things by nature; it can eat, drink, beget, rule, etc.”2
Thus, the absence of free will does not mean we are robots in everyday life.
What Free Will Is
The question of free will concerns matters “above us”—specifically, our “moral ability” to choose actions that lead to eternal salvation. Luther defines free will as “the power of the human will by which a man may apply himself to those things that lead to eternal salvation.”3 The issue is whether our choices can earn righteousness or merit eternal life. Luther’s answer is clear: they cannot.
This question is rooted in the doctrine of original sin. While we may choose to wear a certain shirt, attend church, or help someone in need, these actions do not address the deeper reality of Sin—the condition that renders us spiritually dead. In other words, we might believe our free will operates in relation to individual sins, but our wills remain entirely bound in relation to the condition of Sin. As Ephesians 2:1-9 explains:
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 flesh, carrying out the desires of the flesh and the mind, and were by nature children of wrath, like the rest of mankind. But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved—and raised us up with him and seated us with him in the heavenly places in Christ Jesus, so that in the coming ages he might show the immeasurable riches of his grace in kindness toward us in Christ Jesus. For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast. For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.
Ephesians 2:1-9
Sin’s dominance leaves us spiritually lifeless, unable to move, change, or will our way to salvation. A lack of free will does not make us robots—it’s worse. It makes us spiritual corpses, wholly dependent on God’s grace. Our choices, prayers, or commitments, while real, lack any saving power.
Our will is not free but bound by our sinful nature, chained to sin and death. Even the good deeds we naturally choose cannot save us morally. As Isaiah 64:6 declares, “All our righteous deeds are like a polluted garment.” Our flesh deceives us, masking our spiritual deadness with the illusion of good works: “The heart is deceitful above all things, and desperately sick; who can understand it?” (Jeremiah 17:9). Our bound will tricks us into believing it is free, blinding us to the depth of our captivity.
Living in Light of God’s Will
Acknowledging that sin is stronger than man reshapes how we view our faith. Our salvation rests not on our choices but on God’s. To say it bluntly, a lack of freewill takes salvation completely out of our hands. “Salvation belongs to the Lord” (Psalm 3:8; Jonah 2:9). It’s not our prayers that save us, but Jesus’ intercession. It’s not our commitment that secures us, but Christ’s faithfulness. It’s not our will that redeems us, but God’s electing love.
This truth does not negate our personal walk with God—our choices, prayers, and devotion remain part of our story. God certainly delights to use that stuff. But they are not the source of our salvation. Freewill is a fiction. It does not save. From beginning to end, our hope is anchored in God’s will, His election, His mercy, and the finished work of Jesus Christ on the cross. As Luther reminds us, our assurance rests not in our fleeting efforts but in the eternal blood of Christ. Through Him, your sins are forever forgiven. He has willed to love and save you. It is, truly, finished.
