Martin Luther's The Bondage of the Will is a foundational theological treatise, written in response to Desiderius Erasmus's On the Freedom of the Will, which he wrote in 1524. (i) Luther considered The Bondage of the Will his most important written work, as it defines the core of Protestant Reformation theology regarding human nature and divine grace. In the dispute, Erasmus argued for synergism. The idea is that humans retain a free will that can cooperate with divine grace to achieve salvation.
Luther's thesis: he rejected free will as an empty title, maintaining monergism, the belief that God alone performs the work of spiritual regeneration. Key arguments from Luther’s book are as follows: Luther argued that the fall of Adam completely corrupted human nature. Unregenerate humans are enslaved to sin and Satan, making them totally incapable of choosing spiritual good or seeking God on their own. Luther distinguished between the gospel and God's law. Law reveals human sinfulness and man's powerlessness—rather than offering a checklist for free-will compliance. The gospel freely announces salvation won entirely by Christ. Because human will is bound, salvation depends strictly on God's sovereign election, predestination, immutable knowledge, and grace alone. God must unilaterally change the human heart before a person can truly believe or desire Him. Luther maintained that tying salvation to human willpower leaves people in endless doubt and anxiety. Placing salvation entirely in God's unshakable promise gives believers absolute assurance. (ii)
Luther's critique of Erasmus, and Luther's positive development of the doctrine of predestination involve several major propositions. One, a fallen sinner is totally unable to cooperate with divine grace. Two, salvation is exclusively the result of divine monergism. Three, God foreknows what He does and does what He foreknows. Four, to say that a fallen sinner has the power to cooperate with divine grace is a denial of the necessity of Christ's work. Five, the human will is in bondage to sin because of our union with Adam and his fall. (iii) Six, everything happens according to divine foreknowledge and will, and therefore whatever occurs, in this sense, is ‘necessary’, but not compulsory. Seven, the regenerate and unregenerate act according to their respective wills. Eight, necessity does not destroy moral responsibility (moral free agency). Nine, God's will is immutable. Ten, human free will is a denial of divine freedom. Eleven, free will is an empty term which should be discarded. Twelve, predestination is the sine qua non of assurance. Thirteen, God has predestined some to eternal life, and others to eternal damnation. Fourteen, predestination is fundamentally paradoxical. Fifteen, ought does not imply can. Sixteen, God preached must be distinguished from God hidden. Seventeen, solo gratia, solo fide, denies free will. Eighteen, human inability disproves free will. (iv)
Monergism is the view that when a soul passes from death to life, from unbelief to faith, the energizing power that accomplishes this is the power of God. Luther and the other reformers derive their monergism from the Bible. All the reformers were devout Augustinians and shared Luther's monergism. Prior to Luther's emergence on the public stage, Erasmus had been Europe's foremost advocate of church reform. He had mocked the corruptions within the Catholic Church with devastating satire; he had published new editions of the writings of the early church fathers and viewed them as better guides than the medieval Catholic theologians. Above all, in 1516, he had published a new scholarly edition of the Greek New Testament, the first ever printed edition as a corrective to the Vulgate, the Latin translation that had dominated the Western Church for a thousand years.
When Luther found himself launched into the business of reform in 1517, Erasmus had first supported him; however, despite Erasmus's semi-Protestantism, he could never bring himself to reject the papacy. His ideal was a reformed papacy that championed his views. When he saw Luther, Zwingli, and other reformers denying papal authority and reforming the church in Germany and Switzerland as a non-papal body, Erasmus's blood ran cold. He saw this as a destruction of the church's unity, and he was lobbied by the supporters of the papacy to speak out. Erasmus finally yielded, and in 1524, wrote a book against Luther, titled The Freedom of the Will. Erasmus' choice of topic reflected his theology. He had a high view of the dignity and capacity of human nature, which he felt was being undermined by the monergism of Luther and the other reformers. If God's power in Christ, communicated by the Holy Spirit, was the only power that transformed people from unregenerate unbelievers to regenerate believers, what became of man's own will, capacity, liberty, and choices?
Luther said that human nature outside of Christ was in a helpless and hopeless servitude to sin and Satan. Erasmus saw this as a needless and demoralizing pessimistic view. As a result, he decided to critique Luther's monergism. In its place, he put forth a form of synergism, arguing that God and man worked together freely at every point to achieve human salvation. But Luther indicated that to the Triune God we owe the whole of our salvation: the plan, the provision, and the application. In retrospect, Erasmus' personal variety of synergism came to be rejected even by most Roman Catholic theologians. It gave far too much weight to the alleged autonomy of the human will. Erasmus had declared himself opposed to Luther and the theology of the Reformation. That was, for the time being, enough for Roman Catholics.
Luther responded with The Bondage of the Will in 1525. And this classic statement of the Reformation view of salvation, written with pulsating vigor and vivid eloquence, demolished Erasmus' man-exalting synergism. For Luther, Erasmus was simply failing to take seriously the biblical witness to the depth and gravity of human sinfulness. In consequence, Erasmus also failed to appreciate the profound, radical nature of God's saving activity in Christ and through the Holy Spirit. It's not that God asked people to cooperate with Him in salvation through Jesus Christ. He sovereignly bestows upon utterly lost sinners a new creation, a new birth, a resurrection from spiritual death. To the triune God, we owe the whole of our salvation, the plan, the provision, and the application. ‘Thanks be to God’ is the keynote of all Christian meditation. In this context, Luther also defended the doctrine of election as God's free, unconditional, unmerited choice of sinners. (v)
Luther moves through key biblical passages to prove that Scripture consistently denies human free will and establishes divine monergism.
Key Biblical Texts and Luther’s Arguments
Exodus (The Hardening of Pharaoh's Heart):
Text: God hardening Pharaoh's heart (e.g., Exodus 9:12).
Luther's Argument: Luther argues that Pharaoh did not act with an independent free will; rather, God actively governed and hardened Pharaoh's heart according to His sovereign purpose. This proves that human will is bound and subjected to divine causality.
Romans 9 (Predestination and God's Sovereign Choice):
Text: Paul on Jacob and Esau ("I will have mercy on whom I have mercy") and the potter and the clay (Romans 9:15–21).
Luther's Argument: Paul explicitly strips away human merit and choice. Luther views Romans 9 as one of the clearest testaments to unconditional election and God’s absolute, immutable foreknowledge and control over salvation.
John 6 (The Need for the God the Father to Draw):
Text: Jesus’s statement, "No one can come to me unless the Father who sent me draws him" (John 6:44).
Luther's Argument: Luther stresses the word cannot (the lack of ability/power). He argues that unregenerate humans do not possess the moral or spiritual capacity to turn to Christ on their own; an external, divine drawing and resurrection are required.
Ephesians 2 (Dead in Trespasses and Sins):
Text: Paul writes that humans were “dead in the trespasses and sins in which you once walked” (Ephesians 2:1–5).
Luther's Argument: Luther seizes on the word dead. A spiritually dead person cannot cooperate, choose, or assist in their own revival any more than a physical corpse can raise itself to life. Grace must make a person alive.
Romans 1:18–32 (The Suppression of Truth):
Text: Humanity suppresses the truth in unrighteousness.
Luther's Argument: He shows that unrenewed human reason and the natural will only use their faculties to turn away from God, never toward Him, without the transformative work of the Gospel.
Isaiah 1:18, Imperatives and Subjunctive Moods (Law vs. Gospel):
Luther's Argument: Erasmus claimed commands imply a free ability to obey. Luther countered that biblical imperatives (the Law) are given not to prove we can obey, but to expose our sin, crush human pride, and show us our helplessness so that we rely on Christ in the Gospel (Romans 5:6-11). (vi)
The heart of Martin Luther's theology was the conviction that human beings are totally dependent on God's omnipotent grace to rescue us from the bondage of the will by creating decisively a fulfilling every inclination to believe and obey God. The debates of the 16th century around freedom of the will versus the bondage of the will were not peripheral to the Reformation. They were at the heart of the issue. This is what Luther believed.
Luther said to Erasmus, it is to the highest degree, wholesome and necessary for a Christian to know whether or not his will has anything to do in matters pertaining to salvation. Indeed, let me tell you that that is the hinge on which our discussion turns, for if I'm ignorant of the nature, extent, and limits of what I can and must do with reference to God, I shall be equally ignorant, uncertain of the nature, extent, and limits of what God can, and will do in me. Now, if I am ignorant of God's works and power, I'm ignorant of God Himself, and if I do not know God, I cannot worship, praise, give thanks, or serve Him. For I do not know how much I should attribute to myself, and how much to Him.
Luther knew that Erasmus, more than any other opponent, had put his finger on the deeper issue at stake beneath the justification controversy and the controversy over the Mass, indulgences, Mary, and purgatory. And that issue was whether human beings are so sinful that God's sovereign grace must create and decisively fulfill every human inclination to believe and obey God. Erasmus did not believe this. Luther did, so did Calvin and Zwingli. Erasmus's belief that the fallen human will contributed to its own decisive, self-determining power to an act of faith, and pursuit of holiness was, in Luther's mind, a perilous underestimation of the desperate condition of man without Christ. Luther asserts that the failure to see the gravity of our sin and the depth of our corruption and the bondage of our will, if unchecked, will become an assault on the freedom and sovereignty and the glory of God's grace, and salvation. And therefore, an assault on the very gospel itself.
In 1528, Luther put it like this, “I condemn and reject as nothing but error, all doctrines which exalt our free will, as being directly opposed to the mediation and grace of our Lord Jesus Christ.” By free will, he means decisive self-determination in acts of faith and obedience. For Luther, the issue of man's bondage to sin and his moral inability to believe or be holy was the root issue of the Reformation, and the linchpin of Protestantism. The freedom of God, and therefore, the freedom of the gospel, and therefore, the salvation of men and the glory of God were at stake in this controversy. Therefore, Luther loved the message of his book, The Bondage of the Will. Describing all freedom and power and grace to God, and, for us, complete dependence on God for faith and holiness. (vii)
It is true, he wrote, that the doctrine of the gospel takes all glory, wisdom, and righteousness from men, and ascribes them to the Creator alone, who makes everything out of nothing. Does Scripture describe human beings as so sinful that God's sovereign grace must create and decisively fulfill every human inclination to believe and obey God? There are at least five ways that the Bible describes the bondage every human being is in.
Number one, the bondage of legal guilt and divine condemnation. (viii) Of the 5 descriptions of our bondage, this one is foundational. The other 4 describe conditions of our inner man. This one describes our legal relationship to God. We have sinned against Him and are legally guilty and under His just condemnation. “Now we know that whatever the law says, it speaks to those who are under the law, so that every mouth may be stopped, and the whole world may become accountable to God” (Rom 3:9-10, 19). The word accountable means under the sentence of condemnation—in bondage, awaiting sentence of execution. There's the outpouring of God's wrath on all sinners who do not repent. ‘Under His wrath’ is our primal, legal, objective relationship to God. We have mocked His wisdom, goodness, and authority with our preference for our own way.
Number two, the bondage of love for darkness and self-glorification. Jesus said in John 3:19-20, “This is the judgment: the light has come into the world, and people love darkness rather than the light. Because their works were evil, for everyone who does wicked things hates the light, and does not come to the light, lest his deed should be exposed.” The bondage of the human heart, that keeps it from coming to Christ, is not that light is lacking, but that darkness is loved and light is hated. You cannot embrace as bright and beautiful what you hate; you cannot repudiate as dark and ugly what you love. And hate and love are not decisions. They are profound controlling preferences of the soul. Darkness tastes good. Light tastes bitter. You cannot enjoy as sweet what tastes bitter, and you cannot have a distaste for what tastes good to you. This is a real bondage. These are real ‘cannots’—the kind of inabilities that are blameworthy and culpable, because they're not things we are forced to do against our will. They are our will. And what is it about the darkness that is so enthralling as to hold us in such bondage? Jesus says of those who will not come to Him in John 5:43-44, “I've come in my Father's name and you do not receive Me. If another comes in his own name, you will receive him. How can you believe if you receive glory from one another? And do not seek the glory that comes from the only God?” That's a rhetorical question. It contains its own answer. You cannot believe when you receive glory from one another and do not seek the glory that comes from God. You cannot. Because their love for self-exaltation makes the love of Jesus impossible. Jesus is the light that ends the darkness of all human self-exaltation, but you love the glory of man more than the glory of God. Therefore, you cannot face His light. It's too threatening to what you love (Mt 23:6-7). And His light exposes that the craving for human glory is ugly. So as long as you love the exaltation of self more than the exaltation of God, you cannot taste and see that Jesus is good. You're in bondage to the love of the darkness of self-glorification.
Number three, the bondage of hatred of the supremacy of God. Paul says in Romans 8:6-8, “the mind set on the flesh is death.” It is an orientation, a disposition, a set course, an attitude, but the mindset of the Spirit is life and peace. “But the mindset of the flesh is hostile to God. It doesn't submit to God's law. Indeed, it cannot. Those who are in the flesh cannot please God.” These are very weighty cannots. The disposition, the mindset of the flesh is hostile to God. Why? It is not able to submit to God's law. Indeed, it cannot. There's the answer: the mind which is set on the flesh hates to submit. God is the King, His law is absolute, and the flesh hates God's absolute supremacy. Paul is saying there are 2 kinds of people in the world: those with the mindset of the flesh, and those who have the Spirit of God dwelling in them. “However, you are not in the flesh, but in the Spirit, if in fact, the Spirit of God dwells in you” (Rom 8:9). “Anyone who does not have the Spirit of Christ does not belong to Him.” Every person by nature, apart from the work of God's Spirit, has the mindset of the flesh. We are hostile to God, and cannot submit to a law whose first command is to love the God that you hate. You cannot love what you hate, and apart from sovereign grace, all of us hate being under authority. We are hostile to being under God's authority. We're in the bondage of hatred for the supremacy of God.
Number four, the bondage of spiritual death. When one of the disciples said to Jesus, “Lord, let me first go and bury my father,” Jesus replied, “Follow Me; leave the dead to bury their own dead” (Mt 8:22-23). Paul picks up the language and describes the whole human race as spiritually dead (Eph 2:1-3). Apart from the life-giving grace of God, all of mankind are dead in trespasses and sins; all of mankind follows the Prince of Darkness; all of mankind are sons of disobedience. That is our true nature before conversion, children of wrath. By nature, we are carried by the course of this world; disobedience is not our choice. It is our nature. And in all of those trespasses and sins, we are spiritually dead, utterly unable to feel the impulses of spiritual life. This is the bondage of spiritual death.
Number five: the bondage of blindness to the glory of Christ. In 1 Corinthians 2:6-8, Paul imparts the wisdom of God. It's not the wisdom of this age, nor of the rulers of the age, who are doomed to pass away. We impart a secret and hidden wisdom which God decreed before the ages for our glory. None of the rulers of this age understood this, for if they had, they would not have crucified the Lord of glory. Why didn't they see the glory of Christ? Paul answers in verses 13 to 14. He says that the natural man does not accept the things of the Spirit of God; they are folly to him. He's not able to understand them because they're spiritually discerned. What a sweeping indictment of the human race. The natural person does not accept the things of the Spirit. Why not? Because you cannot accept as wise what you see as foolish. You cannot, and the natural man can only see the wisdom of a crucified Messiah as foolish. Such things are folly to him, and he cannot know them, because they're spiritually discerned. He's blind to such peculiar glory. Our natural blindness is exploited and hardened by the god of this world, who has blinded the minds of the unbelievers to keep them from seeing the light of the gospel, the glory of Christ, who is the image of God (2 Cor 4:4). There is a divine supernatural light that shines through the gospel, namely, the glory of Christ, who is the image of God. No human being, apart from the omnipotent grace of God, can overcome this blindness, nor can see that glory. When they look at it, it is foolish and weak to them, not glory.
Despite all our guilt, all our wicked loves, and all of our hatred of His authority, and all our stone-cold deadness to His sweetness, and all our blindness to His glory, this grace saves us in every way from our own utter enslaving desire to not be saved from these things. To the bondage of our guilt, God says, “Christ bore our sins in his body on the tree, that we might die to sin and live to righteousness” (1 Pe 2:24). “Christ suffered for our sins, the righteous, for the unrighteous, that he might bring us to God” (1 Pe 3:18). We’re justified by His grace as a gift. To the bondage of our love of self, He says, I give you the gift of repentance leading to the knowledge of the truth, so that you may come to your senses and escape the snare of the devil, after being captured by him to do his will (2 Tim 2:25-26). Repentance from evil loves is God's sovereign work. To the bondage of our hatred for the supremacy of God, He declares no one can say, Jesus is Lord, except by the Holy Spirit (1 Cor 12:3). “I'm sending My Spirit into your heart, crying, Abba, Father, and Jesus as Lord” (Rom 8:15-16). To the bondage of spiritual death, He says, “when you were dead in your trespasses, I made you alive together with Christ; by grace, you've been saved” (Eph 2:5). And to the bondage of blindness of the glory of Christ, He says, “let there be light,” and instantly the divine supernatural brightness shone in our hearts to give the light of the knowledge of the glory of God in the face of Christ (2 Cor 4:6). (ix)
Luther was right about this: unless we feel the power and the pervasiveness and the eternal peril of the bondage of our will, we will not see, or savor, or sing the glory of God's sovereign grace. (x) Are human beings so sinful that God's sovereign grace must create and decisively fulfill every human inclination to believe and obey God? Luther's answer, and of all the reformers, was yes. And fallen man cannot create his own holy choices. In fact, in the act of faith and pursuit of holiness, man does not complete God's prevenient grace by contributing his own decisive, self-determining power. The stranglehold of our bondage is such that God must create and decisively fulfill the act of faith. And the pursuit of holiness. (xi)
