John 8:30-36 Discover True Freedom in Christ , Part 1 — John 8:30-34
No chains can constrain the love found in Christ Jesus!
“30 As He spoke these things, many came to believe in Him. 31 So Jesus was saying to those Jews who had believed Him, “If you continue in My word, then you are truly disciples of Mine; 32 and you will know the truth, and the truth will make you free.” 33 They answered Him, “We are Abraham’s descendants and have never yet been enslaved to anyone; how is it that You say, ‘You will become free’?”
34 Jesus answered them, “Truly, truly, I say to you, everyone who commits sin is the slave of sin. 35 The slave does not remain in the house forever; the son does remain forever. 36 So if the Son makes you free, you will be free indeed.” (NASB)
We all value freedom. Youth aspire to a better life because they seek the freedoms of adulthood. People seek wealth and the freedom it brings. Couples seek freedom within marriage. Countries desire their sovereignty. But what constitutes freedom? I’m afraid that in this hedonistic age, people have confused their lusts with freedom.
Jesus redefines freedom in John 8:30-36. He teaches that freedom comes from knowing and living out His words. If this definition sounds too constraining, listen carefully, for these are the words Jesus uses. Life and true freedom are found in Jesus Christ and His Words. In a parallel vein, freedom is lost, and slavery is adopted the more our lives are less impacted by the words of Jesus.
Let me first state what true freedom is not.
True freedom is not merely expressing our feelings. Some think that saying what they feel would make them free. This is ‘Freedom of Expression’ taken to an extreme. Here’s a test of reality. When we always speak our feelings, we unnecessarily hurt people. The book of Proverbs says it is unwise to express our anger because it only makes things worse. Conversely, Jesus states that freedom enables us to do God’s will—marked by self-control.
True freedom is not the satiation of our desires. I’m not free when I get everything I desire. Just because one desires a product or a person does not mean that their life would be better if they got it. The Bible clearly says that covetousness is wrong, and those who follow their lusts end up with disastrous results.
True freedom is not found in our social system. Somehow, modern cultures have turned toleration into a license to do whatever one wishes, without criticism from the surrounding society. This kind of toleration is not the hallmark of a free society but of a rapidly degenerating culture. In today’s world, justice is twisted. Those who stand up for what is right are sued. Meanwhile, wrongdoers commit ever more evil. This is not freedom but wretched captivity with horrible consequences.
True freedom is not found in political or economic systems outside of God, including the so-called democratic movement. True freedom comes when people come under the rule of Jesus Christ (cf. Isaiah 9:6-7).
True freedom, instead, enables one to do what God originally designed. God, Our Designer, has plans for your life. True freedom rests in doing what one should do, not in doing what one is forbidden (1 Samuel 15:23).
Freedom is the ability to fully fulfill the purpose for which God created you.
Let’s now turn to the Master Teacher, Jesus Christ, and join a crowd listening to Him speak on this topic.
Culture Problems
People have long confused the Gospel’s essential work with its effects. We face this challenge in unprecedented ways today, as many Christians shift their allegiance from Jesus’ words to what they believe are the Gospel’s positive effects. The Dark Ages darkened much of Europe largely because people lost connection to Jesus’ words. The Reformation succeeded only where people rediscovered and reclaimed the truth of Jesus’ words.
We need to be extremely wary of anyone, including Christian leaders and groups, who shift their foundation from Jesus’ words to popular and cherished slogans.
In John 8:30-36, John offers unique insights not only into what we should be seeking but also into the wrong assumptions we hold about freedom and slavery. Contemplate the glory of the freedom found in Christ, wherever you are now. With this challenge before us, let us step into the first main point: Freedom and Delight.
1. Freedom and Delight (John 8:30-32)
“30 As He spoke these things, many came to believe in Him. 31 So Jesus was saying to those Jews who had believed Him, “If you continue in My word, then you are truly disciples of Mine; 32 and you will know the truth, and the truth will make you free.” (John 8:31-32)
The world persistently portrays truth as boring, constraining, and tedious. Jesus, however, interestingly links truth to freedom, like a kite whose flight depends on the string held to the ground. Release the string, and the kite falls to the ground, tragically and abruptly. Let’s see how Jesus presents His case. Whether religious or not, the modern world has perilously forgotten that genuine freedom is tethered to the truth of Jesus’ words.
Belief in Christ
John first notes that many Jews came to believe in Jesus: “Many came to believe in Him” (John 8:30). Saving faith is the greatest life-changing miracle—a change of heart and faith. Many want to see a healing miracle or another sort of miracle, but nothing proves God’s existence today as much as the change in people’s lives.
Belief in Jesus is more important than anything else in life, so it’s tremendous to see so many people believe.
However, there are a few reasons to question their belief in Jesus. John first notes that they had doubts—“They did not realize….” But later he calls them believing Jews. Perhaps when Jesus said, “When you lift up the Son of Man, then you will know that I am He” (John 8:28), they expected Jesus to reveal His great powers and overcome the Romans.
“27 They did not realize that He had been speaking to them about the Father. 28 So Jesus said, ‘When you lift up the Son of Man, then you will know that I am He, and I do nothing on My own initiative, but I speak these things as the Father taught Me.’” (John 8:27-28)
It’s an eternal mistake to make one’s faith a secondary or extraneous decision in life. John reaffirms this when he defines the purpose of John’s Gospel: “But these have been written so that you may believe that Jesus is the Christ, the Son of God; and that believing you may have life in His name” (John 20:31).
Do you believe in Jesus? Jesus says,
“Truly, truly, I say to you, he who hears My word, and believes Him who sent Me, has eternal life, and does not come into judgment, but has passed out of death into life” (John 5:24).
This leads us to two questions. (1) What happens when a person believes in Christ? (2) What happens after one believes in Christ? Jesus doesn’t say much about the first question here, as in John 3 and 4, but focuses on the second. But let me first summarize the powerful work of God that takes place every time someone is born from above (John 3).
The Spirit convicts us of our sin and then causes us to be born again through the living Word of God.
“3 Blessed be the God and Father of our Lord Jesus Christ, who according to His great mercy has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead, 4 to obtain an inheritance which is imperishable and undefiled and will not fade away, reserved in heaven for you” (1 Peter 1:3-4).
Our living God initiates these authentic experiences; we respond. We must not reduce them to mere religious experiences; they are genuine and foundational. (Of course, the evil one is falsely motivating some to falsely confess Christ.) God is likewise at work today. He works in our lives not because we are morally acceptable but according to His great mercy (1 Peter 1:1-3). People share their testimony because the resurrected Lord has shown them God’s wonderful love.
Jesus points out that saving faith is only the beginning, not the end.
What happens after one believes in Christ?
The purpose of our lives is not to gratify our immediate desires but to accomplish God’s purposes for our lives. Freedom is found in becoming Jesus’ disciples. The real question in life is not getting what we want but doing what we are supposed to do. It is not about being someone else, but about being conformed to His purposes for us. Jesus told them that the way to real freedom is to be His disciples. Let’s see what He told them in John 8:31-32.
Jesus describes three results of securing spiritual freedom by faith in Christ; it’s portrayed as both an event and a process. The three facets work intricately together, though they may appear to happen simultaneously: 1) Continue in My Word, 2) Know the Truth, and 3) The truth sets one free.
(1) Continue in My Word
FFaith or belief in Christ begins the process of learning Jesus’ teachings. Genuine disciples are not merely those who hear or acknowledge the words of Jesus but those who live according to them, as Jesus says, “You continue in My Word.”
Jesus distinguishes between those who believe (“Many came to believe in Him”) and those who persist in their faith—those who continue in Jesus’ Word. Jesus is not saying one has to do these things to become a Christian. This continuation in His Word directly results from genuinely coming to know the Lord. Again, it’s wrong to assume that this level of obedience is what it takes to believe in Jesus. Clearly, it’s faith, but it’s a saving faith that produces obedience.
Think of it as a meeting with God that never leaves you the same. God’s love is born in you, producing love for God, His Word, and others.
Genuine faith in Christ stirs deeply within believers, causing a deep desire to know and obey Jesus’ Word. We can readily see this change in new Christians who suddenly love to hear and do God’s Word. His Word becomes their food (Heb 5:12-14).
(2) Know the Truth
The second step is the doing of Christ’s word—knowing the truth. Sometimes we demand to see the truth before we commit ourselves to the Lord. This is senseless. One can try to teach a dead man many things, but he can’t learn. A person first needs to be born again with new life, and then, being alive, he can understand and grow. However, we should keep in mind that the Spirit’s work unto conversion often works in an individual over time.
Disobedience cuts off growth because it keeps the truth from entering. We disallow a particular part of our lives from being corrected by Jesus’ words.
Some of you might get mad at the way we assert our knowledge of the truth. I can understand, but test His words if you will! Ask new Christians how they considered themselves blind before they became Christians. Life precedes the living out of these truths.
Knowing the truth is like a computer program. A computer might be plugged in and running, but it still needs a major operating system and smaller programs to be usable. God’s code is His truth, Jesus’ words. The Christian, now possessing life, seeks to acquire God’s Word and live by it so they can live out God’s design for their life. (I remember, back in the mid-80s, writing a program for my computer to practice my Mandarin and Taiwanese vocabulary. A few hundred lines of BASIC code helped me improve my language learning significantly.) Our hearts are now compatible with this truth, and when directed by it, our paths are set. We adopt His thoughts and desires, making them central to our lives.
Jesus says, “You will know the truth.” Is this truly a one-time experience? Yes, but the question leads us in the wrong direction. Knowing the truth is like opening a blind man’s eyes, enabling him to see so many things he couldn’t before. The gift of sight brings a believer into a whole new world of experience. Now he sees things in the car, on the elevator, and even on an evening walk. Knowing the truth results in ongoing acquisition and access to that truth.
Salvation is a package deal. The initial changes open one up to all sorts of truth experiences. Holding the key to a house allows you to explore the entire place.
One of the greatest follies is to gain that eyesight but keep one’s eyes closed, or to possess that key but never explore all the rooms, or to be content with a darkened closet. And so, one of the greatest mistakes a believer can make is to think that the initial “know the truth,” being saved, is the sum total of being a Christian! åA saving faith is fantastic, but it only jets us into the stream of eternal life. Who would be content with birth when there is a life to live?
This is what Jesus says. We continually acquire and experience God’s Word, as shown in His words, “If you continue in My word” or “You are truly disciples of Mine,” and in the effect that “the truth will make you free” (John 8:31-32).
One of my biggest challenges as a teacher of God’s Word is to help Christians see that the greatest is yet to come! A believer’s growth is not measured by how much he gives or how often he comes to church, but by abiding in Jesus’ Word and letting it direct his path (cf. the vine in John 15).
I wish believers would pursue doctrinal purity and insist on the Christian’s spiritual development. Jesus was not willing to let these many new believers fool themselves now that they count themselves among His number.
(Behind the “knowing the truth” is the battle for the supremacy of God’s Word, which persists to this day, even in mainline denominations. Many have left God’s Word, as shown by leaders with no interest in it, leaving their denominations without a firm foundation, and many have disappeared.)
(3) The truth shall make you free
Jesus declares the third element of this belief process, “You shall know the truth, and the truth shall make you free.” Free in what way? Free to do what we were created to do. Free to do all the things we should do. Free to be ourselves.
With this ‘freedom’ comes the real meaning of life we have been searching for. They now abide in Jesus’ Word. Christ’s Spirit leads and lives in them. This leads us to the second step. Jesus sought to clarify what was happening. Some are believers but not disciples of Jesus. For this reason, many teachers, including me, speak of “professing faith,” in which one confesses belief in Christ but must give evidence of that faith.
The Reformers rightly insisted on the perseverance of faith, which is Jesus’ point. The Spirit of God originates life from His Word of Life, which in turn brings a growing, persistent faith.
Time is needed to prove each of us. Jesus’ words, “If you continue in my word,” anticipate a deeper, ongoing conviction. These are Jesus’ true disciples. On the other hand, some professors of Christ want only a general association with Jesus and lack a true commitment to His words. They believe that association, like a good-luck charm, will provide extra benefits in life.
Captivity is doing things one was not designed to do. It is what we call sin. For example, would a fish consider itself free if taken from a river and put on land? Or again, if a computer is not powered on, the screen goes black—even without a screen saver. God’s truth restores freedom to human beings by bringing them back to the environment in which they were made to live—God’s presence. It is liberating because it is right, natural, good, and beautiful. God made people in His image, bringing about a restoration that leads to true freedom.
For example, one person might be a habitual liar. He lies to get what he wants. He thinks he is better off lying and has deluded himself into not questioning its impact on his life. Though he gets some things by lying, he loses in the long run. The liar convinces himself that he is doing great because he thinks his lies help him. But lies hurt people. Lies create superficial people. How can you have a friend if you lie to those around you? You don’t. You are disloyal, but to be a friend, you must be truthful. People find that if they cannot trust you in one area, they cannot trust you in other areas. If a person lies, it proves he puts his interests ahead of others’.
Lying negatively affects your career; it destroys your marriage and guarantees your spot in hell. Now you might have grown up thinking that these relationships can never be good. But this is not true. Jesus brings the truth that helps us form strong friendships and marriages. We are not going to flatter or show off, but to care for others. Let love replace your selfishness and transform your lives. You will become free.
Jesus says He has come into the world to set us free from the patterns of sin that have frustrated and troubled our lives. The more we go against Christ’s words, the more our lives become snarled and twisted. But as we abide in His Word, we reverse that cycle. He leads us into the truth, which leads us into freedom.
Someone once asked, “Is there sufficient evidence to convict you of being a follower of Christ?” It’s a good question for all of us.
2. Slavery and Delusion (John 8:33-34)
33 They answered Him, “We are Abraham’s descendants and have never yet been enslaved to anyone; how is it that You say, ‘You will become free’?”
34 Jesus answered them, “Truly, truly, I say to you, everyone who commits sin is the slave of sin. 35 The slave does not remain in the house forever; the son does remain forever. 36 So if the Son makes you free, you will be free indeed.”
Everyone loves to hear about freedom. For most, it means release from oppression. The Jews lived under strict Roman rule; one corner of the temple area had become a Roman fort.
The Jews, however, realized that Jesus was pointing to something much deeper than mere choice and belief. As a clever teacher, He pointed to their chains. They, like all, resentfully resisted the implication that they were enslaved and asserted that they were sons of Abraham. What they said was true about being Abraham’s children (not in Paul’s language, where they clung to the Law - Ishmael), but the Israelites were, at times, held in captivity.
The most significant and telling teaching here is Jesus’ definition of slavery: “Everyone who commits sin is the slave of sin” (John 8:34). This problem explains both the global problem and the social and individual problems of society—sin. Sin here means “missing the mark” or wandering from God’s divine law. Jesus uses it decisively, starting in verse 21 and concluding, “For unless you believe that I am he, you will die in your sins” (John 8:24).
Jesus claims to be equal with Yahweh God through the phrase, “I am He,” the everlasting self-existing One. The personal Creator God came to earth to seek us. If we miss this truth—like missing a plane or mistaking a bridge—we will die in our sins.
What do you think is most important for us as a culture right now? In a society like ours with a strong Christian base, people don’t typically outright deny Christ, but they begin to marginalize His influence. They want us to accept Jesus’ teachings as having equal authority and weight to others’.
Jesus, however, states that life begins with His Words. Without them, without belief in Jesus’ work on the cross and His resurrection, you will die in your sins and suffer the consequences of eternal damnation.
But you say, “Our sin isn’t that bad,” yet did you note Jesus’ clarification? He who sins is the slave to sin. This includes us all. Sin shows that we belong to the evil one and live out his ways. Sin, then, betrays our pretended innocence. Sure, you might convince yourself that you are better than another, but are you sinless? No, you have missed the mark (Rom 3:23).
Jesus answered them and us in a simple yet powerful way. “Truly, truly, I say to you, every one who commits sin is the slave of sin.” He cuts through their emotions with one statement. Jesus says that our imperfect behavior shows a greater power controlling us. Think of all the things you knew you should do. You should be honest or kind, but you were not. You recognized in your heart what was proper. If it was not proper, why did you give in and do evil? It is because you submitted to your sinful desires. In a real sense, you served a power that was not really yourself—your sin. So Jesus adamantly says, “Truly, truly, I say to you, everyone who commits sin is the slave of sin.”
Just think. If you knew something was wrong but still did it, doesn’t that show a stronger power at work in your life? Doesn’t it prove that you did something you knew you shouldn’t do?
Like the Jews, we are not free from this condemnation in Jesus’ words. We are obviously guilty because we have sinned. The more one sins, the more its power becomes evident. I have met alcoholics, drug users, liars, etc., who say they can’t change. The bitter person says he can’t forgive. But even a little sin admits that we are slaves to sin and need to be set free.
