So Jesus said to the Jews who had believed him, “If you abide in my word, you are truly my disciples, and you will know the truth, and the truth will set you free.” They answered him, “We are offspring of Abraham and have never been enslaved to anyone. How is it that you say, ‘You will become free’?” Jesus answered them, “Truly, truly, I say to you, everyone who practices sin is a slave to sin. The slave does not remain in the house forever; the son remains forever. So if the Son sets you free, you will be free indeed.” (John 8:31–36, ESV)
Grace and peace to you from our Lord and Savior, Jesus Christ. Amen.
Luther Before the Emperor
Martin Luther stood before Emperor Charles V at the Diet of Worms. It was April 1521. The Church, with the force of the government, demanded that Luther retract his writings. It wasn’t an idle threat. One hundred and six years before, John Huss was executed for saying many of the same things. Luther’s life depended on his answer.
Luther’s response is powerful.
I am bound by the Scriptures I have quoted and my conscience is captive to the Word of God. Here I stand; I can do no other , God help me. Amen.
Do you understand what he was saying? Do you know what he meant?
The two words that drive the quote are bound and captive. He is bound to Scripture, and captive to the Word of God. In other words, the Pope, the Church, the government don’t drive his beliefs. It is the Bible, God’s Holy Word, the Holy Scriptures. What God says, not what people say. He is willing to die (that threat was very real) rather than compromise what God says.
But what Luther said sounds like the opposite of freedom. The words bound and captive, don’t sound like freedom. They sound like slavery.
Is Luther giving up one form of slavery for another?
No, his captivity frees him from every demand to justify himself. It frees him from the demands to make a confession that isn’t based on Scripture. It frees him from his own opinions.
How can a captive conscience be a free conscience?
Abide in My Word
In our text Jesus is speaking to people who believed in him. He says,
If you abide in my word, you are truly my disciples, and you will know the truth, and the truth will set you free.
Jesus uses the word abide. He is saying live in my word. Let my word direct what you believe. If you follow me, follow me by what I have said.
He doesn’t tell them to look inside themselves for answers. He doesn’t tell them to depend on their feelings. He directs them away from their ancestry. He doesn’t say that his word is subjective, that it is based on a person’s experience and internal thoughts. He says abide, remain, continue, and dwell in my word. Jesus says that faith in him lives by a continuous receiving of His Word.
For Martin, his conscience had been captive to other words. He was told that God was an angry judge. He was told that he had to make satisfaction for his sins. He was told that he must become righteous enough to be accepted by God. He never knew whether he had done enough to please God and become righteous. He was told his standing before God depended on his spiritual performance.
He saw that the harder he worked, the less free he became. He entered a monastery. He prayed, fasted, confessed, studied and disciplined himself. He could confess individual sins, but he could not remove his sinful condition. Everything he did had the opposite effect of what he desired. There was no certainty. Every sin he uncovered pointed to another, until he realized that it wasn’t the sin, it was that he was a sinner.
You can see it in the world around us. The controlling words of society. They tell you; you are what you accomplish; You are what other people think of you; You have to justify your past; You have to prove you deserve you place; You must be good enough to please God or he won’t receive you.
The question isn’t whether your conscience is captive. The question is which word holds it.
We Have Never Been Enslaved
In the Gospel of John, Jesus promises freedom. The Jews who had believed in him reject what he says.
We are offspring of Abraham and have never been enslaved to anyone.
What they were saying is that they depended, their confidence was in, who they were, their ancestry. They were entitled to standing before God because of who they were. The confidence wasn’t found in who Jesus is.
During the festival of Reformation, we would do well to consider where we stand. We are Lutherans. Our confession of faith is correct. Saved by grace alone, is our constant mantra. We believe it. We are not like the churches who push their works before God as proof of salvation. Our history is solid, we confess the faith passed down through the ages from the Apostles. We confess a doctrine that is captive to God’s Word.
Our doctrine is precious because it confesses Christ crucified for our forgiveness. Sola Scriptura scripture alone drives it.
But if it becomes another object of boasting; if it becomes a reason to avoid repentance; we are in the same place as the people Jesus was talking to in the text for today.
We can know the vocabulary of grace, but that isn’t the same thing as receiving Christ’s grace.
A Slave to Sin
Jesus says,
Everyone who practices sin is a slave to sin.
Practices is a present participle. It denotes ongoing actions. Jesus is not describing one isolated act as though one sin suddenly turns an otherwise free person into a slave. A more literal translation is, everyone who is doing sin. In other words, Sin is not merely something free people occasionally do. Our doing of sin reveals that sin is our master.
It isn’t an occasional mistake. Jesus isn’t making categories of sinners. It applies to everyone. It is part of our inborn sinful nature. It commands us to hide, excuse, blame, compare and justify ourselves. Doing sin shows who is the master. Sin doesn’t create the master.
Paul says it clearly.
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 be held accountable to God.
Every mouth and the whole world. That’s very inclusive. It includes Lutherans.
Luther saw it. He understood the accusation of the Law. He knew that outward obedience could not conceal the heart from God. He saw that God demands perfect fear, love and trust—not simply respectable conduct.
In fact, the more seriously he took the Law, the more clearly he saw he was a slave.
His problem wasn’t that he didn’t try hard enough. There was no amount of human effort that could make him righteous before God. No amount of doing good things would satisfy what God demands.
And Jesus describes the consequences.
The slave does not remain in the house forever.
Slaves have no permanent claim in the household. Sin leaves the sinner without a rightful place before God. Monastic discipline could not turn Luther from a slave into a son. Church membership, moral improvement, and doctrinal knowledge cannot give us that place. We can’t change our slave status by doing anything. Slaves can’t free themselves. They can’t earn a place in the house. So, who can?
Jesus.
The Son Remains Forever
He isn’t another servant trying to satisfy the Father. Jesus is the eternal Son of God. He belongs in the Father’s house. Unlike every reformer, pastor, ruler and institution, the Son remains forever.
And yet, He takes the place of slaves. He “emptied himself, by taking the form of a servant”—literally, the form of a slave (Philippians 2:7). He was “born under the law, to redeem those who were under the law” (Galatians 4:4–5). He is obedient where slaves rebel. He isn’t a slave to sin.
Jesus bears the condemnation that belongs to slaves of sin. Rejected and crucified, treated as one who has no place, he sheds His blood for redemption of sinners. He rises from death as the Son who remains forever.
Jesus Christ is treated as one without a place so that sinners may receive His place in the Father’s house.
Luther didn’t find a better method of becoming righteous. The Law can’t justify. It only exposes sin. Jesus did everything necessary to save sinners, through His precious blood and innocent suffering and death. And it is provided to them through grace. That is God’s undeserved gift. Faith is the receiving hand that receives the external promises of God. It doesn’t depend on anything else.
Romans 3 supplies the Reformation confession:
All have sinned. Every mouth is stopped. Sinners are justified freely by grace. Redeemed by Christ alone. His blood is the paid price. Faith receives the gift. And there is no bosting.
Jesus doesn’t give us, slaves, instructions for becoming free. He acts. His Word declares and accomplishes that freedom. Our faith doesn’t finish what Christ started. It receives the verdict.
Now our consciences are free from the Law’s condemnation. We are free from trying to free ourselves. There is nothing left for us to do.
Freedom Delivered
And it isn’t just an empty promise. Jesus uses concrete means to bring us the truth and produce the freedom of forgiveness. He places his name on sinner through Holy Baptism. It joins us to Him. Christ speaks forgiveness into our ears through a pastor. He preaches announces and gives the truth about His death and resurrection. It delivers what it promises. And in His supper, he gives us His body and blood for our forgiveness. It is concrete, solid, sure based on God’s promises.
Back to Worms
Martin Luther stood before Emperor Charles V at the Diet of Worms. It was April 1521. Luther had no military power of personal security. He wasn’t confident in himself. He didn’t have unusual courage. His conscience is bound, he said, to a Word greater than an emperor command, a popes condemnation, and even his own fear. It was God’s Word that declares that Christ made satisfaction for sin. Luther stands because his standing before God has already been given in Christ. His conscience is free, precisely because it is captive to Christ’s Word and promise.
The Gospel Remains
On Reformation we don’t merely remember what Luther did. When we talk about reformation we are talking about an ongoing reformation. The church is reformed whenever God’s Word exposes false confidence; where His Word stops human boasting; where His Word calls sinners to repentance, and points them outside of themselves, gives them Christ’s completed work and frees them through forgiveness.
The Church does not remain because Luther was courageous. It does not remain because pastors are permanent. It does not remain because institutions are strong. The Gospel remains because the crucified and risen Son remains forever.
A Captive Conscience Set Free
So, how can a captive conscience be free?
A conscience captive to sin is condemned. A conscience captive to human approval is afraid. A conscience captive to personal performance moves between pride and despair.
A conscience captive to Christ’s Word hears: Christ has borne your sin. Christ has paid the entire price. Christ gives you His righteousness. Christ has brought you into His Father’s house. Christ’s promise does not depend upon your performance.
Luther’s conscience was free because it was held by that Word.
Your freedom does not rest upon Luther’s courage or your own. It rests upon Jesus Christ—the Son who took the slave’s place, set you free, and remains forever. Amen.
The peace of God that passes all understanding, keep your hearts and minds in Jesus Christ. Amen.
