Killing Your Sin
Colossians 3:5-11
My sermon today is on “Killing Your Sin” which comes from Paul’s command in Colossians 3:5, “Therefore put to death your members which are on the earth …” This is similar to what Paul says in Romans 6:11, “Likewise you also, reckon yourselves to be dead indeed to sin, but alive to God in Christ Jesus our Lord.” But the command in Colossians 3:5 is stronger than just considering or reckoning ourselves to be dead to sin. Rather, the idea here is that we are to put sin to death, to kill sin. Paul isn’t instructing us merely to decrease our sin or wound it a little. He isn’t telling us to not think about it or cover it up. The idea here is to root sin completely out of our members, destroy it, and throw it away. We are to treat sin as we would a mortal enemy, showing no mercy by utterly eradicating it. One preacher said, “You don’t trick it, train it or tame it; you terminate it.”[1]
1. What does it mean for us to kill sin?
Frist, it implies that sin is an extreme problem which requires an extreme solution. It is like the urgency that Jesus taught when He taught against adultery, saying,
29 “If your right eye causes you to sin, pluck it out and cast it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell. 30 And if your right hand causes you to sin, cut it off and cast it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell.” (Mat 5:29-30).
Very clearly, Jesus is not telling us to literally cut off our hand or pluck out our eye. Remember that in Colossians 2, Paul showed that ascetic practices of “false humility and neglect of the body” have “no value against the indulgence of the flesh” (Col. 2:23). Sin does not originate in our hands and eyes, it comes from our minds and hearts. Jesus is teaching us to deal drastically and decisively with sin—to kill it immediately before it spreads and takes over. Paul expressed this same urgency in Romans 8 when he wrote, “For if you live according to the flesh you will die; but if by the Spirit you put to death the deeds of the body, you will live” (Rom. 8:13). Puritan John Owen in his work, Of the Mortification of Sin in Believers, famously wrote about that verse, “be killing sin or it will be killing you.”[2] Joel Beeke wrote…
I once read of a missionary who had in his garden a shrub that bore poisonous leaves. At that time he had a child who was prone to put anything within reach into his mouth. Naturally he dug the shrub out and threw it away. The shrub’s roots, however, were very deep. Soon the shrub sprouted again. Repeatedly the missionary had to dig it out. There was no solution but to inspect the ground every day, and to dig up the shrub every time it surfaced. Indwelling sin is like that shrub. It needs constant uprooting. Our hearts need continual mortification.[3]
The basis for this command for believers to kill sin can be found in the first word of Colossians 3:5, “Therefore.” It points back to the description of our union with Jesus Christ in Colossians 3:1-4. As believers in Christ, we are united with Christ. We died with Christ (Col. 3:3); we were raised with Christ (Col. 3:1); Christ is our life (Col. 3:4); and we will be glorified with Christ when He appears (Col. 3:4). Our union with Christ is the basis for living a transformed life in Christ. So, because you are united with Christ in His death, resurrection, ascension, and return, you must kill the sins Jesus died to save you from. In other words, we are to live out practically who we already are positionally.
We are dead, therefore we must “put to death your members which are on the earth” (Col. 3:5). In the plural (as in this verse) “members” refers not just to your physical limbs but to the seat of your desires and passions. Your “members” are your physical mind and body so far as they are employed in the service of sin. Paul is not teaching that matter is evil or our bodies are evil – that was the philosophy of the false teachers. Our bodies are not evil, but they are corrupted by sin and are susceptible to be used by sin. You died with Christ, but you still fight the battle against sin in your members. You have habits of your mind, attitudes of your heart, and behaviors of your body that, in your life before Christ, were accustomed to sin.
Now, even though you have been born again as a child of God, a new creation in Christ so that “old things have passed away,” and “behold, all things have become new” (2 Cor. 5:17), yet sin still plagues your members. It is an ongoing battle that we face. Paul describes it in Romans 7 this way:
22 For I delight in the law of God according to the inward man. 23 But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members. 24 O wretched man that I am! Who will deliver me from this body of death? (Rom. 7:22-24).
Paul’s answer to that question in Romans is the same as his answer here in Colossians, “through Jesus Christ our Lord!” (Rom. 7:25). The way that we overcome sin in our members is to kill it by our union with Christ and His indwelling Spirit. Sin should have no more life in your earthly members.
In Colossians 3:8, Paul uses another metaphor, that of removing clothing. He writes, “But now you yourselves are to put off all these.” The idea is to throw it off and be done with it for good. Paul uses a similar image in Romans 13:12 when he writes, “The night is far spent, the day is at hand. Therefore let us cast off the works of darkness, and let us put on the armor of light.”
During the Civil War, a Confederate soldier from Virginia became so tired of living in his lice-infested clothes that he decided to do something about it. He wrote his wife with instructions to meet him at a certain place on a certain day, bringing with her a fresh change of clothes and a jug of kerosene. The soldier met his wife at the designated spot, bathed in the kerosene to rid himself of the lice, then burned his infested clothes and returned to his unit.[4]
That’s what Paul says we must do with sin. Strip it off like a filthy, infested garment, burn it, and be rid of it for good. As a believer in Christ what do you do with sinful thoughts, desires, and behaviors? Put them to death and remove them like an old piece of clothing.
In Colossians 3:5 and 3:8-9, Paul gives us specific examples.
2. What are some sins to put to death?
What are we to put to death? Paul gives two lists of sins. In Colossians 3:5, he gives the examples of personal, sensual sins or sins of idolatry: “fornication, uncleanness, passion, evil desire, and covetousness, which is idolatry,” (Col. 3:5). These, we are to kill. Then in Colossians 3:8-9, Paul gives the examples of relational sins or sins of hostility: “anger, wrath, malice, blasphemy, filthy language out of your mouth” and lying to one another. These, we are to put off.
Paul says these are some of the things you must put to death in your life. The word translated “fornication” is sexual immorality. It is associated with excess and indulgence of every kind of extramarital, unlawful, or unnatural sexual activity. This would include premarital sex, prostitution, adultery, homosexual relations, incest, and even such things as pornography or sexual fantasy. Paul says as a believer in Jesus Christ you must put these things to death.
Second on the list is “uncleanness.” This word describes anything that is filthy or dirty or impure. Figuratively it refers to moral impurity in thought, word, and deed. It reminds us that sexual sin even on the thought level defiles us. To the Thessalonians Paul writes, “For God did not call us to uncleanness, but in holiness.”
Next on the list is “passion.” All three times this word is used in the New Testament it refers to out of control sexual lust (Rom. 1:26; 1 Thess. 4:5). This is tied to the fourth, “evil desire” which is wickedness as an evil habit of the mind. Jesus used this word to describe the wrongful lust for a woman (Matt. 5:28). Paul used this word to describe the sinful craving for idols and other gods (1 Cor. 10:6). James used this word to describe the selfish desires that creates fights and quarrels among people in the church (James 4:2). Evil desire is simply any sort of desire that’s a wrong desire.
The final one on this list is “covetousness” which literally describes a strong desire to acquire more and more, an insatiable selfishness. It can be the desire to have more money, more things, more power, more fame. In this context it also refers to the desire to have more forbidden sex. That’s why when the tenth commandment says, “You shall not covet,” it specifically includes, “You shall not covet your neighbor’s wife.” (Exodus 20:17). Covetousness is the desire for more of what’s not yours. It takes the place of God and God’s will for your life. It’s like “He’s not meeting my needs,” or “She’s not meeting my needs. I want something more.” That’s covetousness.
Paul says “covetousness … is idolatry.” Ephesians 5:5 also makes that connection, Paul writes, “For this you know, that no fornicator, unclean person, nor covetous man, who is an idolater, has any inheritance in the kingdom of Christ and God.” Idolatry is putting something else before God. It is setting your hearts and minds on earthly things rather than things above. In the Bible, idolatry is often connected to sexual immorality. Describing the result of rejecting God for idols, Paul writes in Romans 1, “Therefore God also gave them up to uncleanness, in the lusts of their hearts, to dishonor their bodies among themselves, who exchanged the truth of God for the lie, and worshiped and served the creature rather than the Creator, who is blessed forever. Amen.” (Rom. 1:24-25).
All of these are issues of the mind and the heart. By the way do you know what is the number one most obvious cause of all sexual immorality today? It’s not the cell phone in your hand; it’s the love for sin in your heart. Listen, the Colossians didn’t have cell phones, and yet Paul was still telling them put sexual immorality to death[5]
I don’t know if you are allowing any of these things a place in your life right now. But I can tell you this: the answer isn’t to try to cope with or control your sin. It’s an idol. Make a clean break with it. Put it to death. Kill that sin.
Notice in Colossians 3:8-9, the second list, “8 But now you yourselves are to put off all these: anger, wrath, malice, blasphemy, filthy language out of your mouth. 9 Do not lie to one another, since you have put off the old man with his deeds,” These are interpersonal sins or sins of hostility. They deal with your heart toward other people.
“Anger” is the sin of an internal hostility toward others, a deep, smoldering, resentful bitterness. It’s a settled animosity toward another person. “Wrath” refers to a burning anger which flares up and burns with the intensity of a fire. It manifests in sudden outbursts of temper and explosions of rage. “Malice” is a mean-spirited or vicious attitude that wishes or does harm to others. Malice is glad when the other person is hurting and sad when they do well. Anger, wrath, and malice are heart-level sins that reside just below the surface, often boiling over into hurtful words and deeds.
The next three have to do with our words. “Blasphemy” is slander or speech that denigrates or defames. Obviously, blasphemy against God is a great sin, but this sin also includes slander against men, wounding someone’s reputation by evil reports, evil speaking. “Fithly language” is to be foul-mouthed, speech that is obscene, filthy, or abusive. Finally, Paul says in Colossians 3:9, “Do not lie to one another.” Lying means to tell a falsehood with the intent to deceive. The command is to “stop lying” or “do not have the habit of lying.”
Paul gives similar instructions in Ephesians, he writes in Ephesians 4:29, “Let no corrupt word proceed out of your mouth, but what is good for necessary edification, that it may impart grace to the hearers.” And then in Ephesian 5, “3 But fornication and all uncleanness or covetousness, let it not even be named among you, as is fitting for saints; 4 neither filthiness, nor foolish talking, nor coarse jesting, which are not fitting, but rather giving of thanks.” (Eph. 5:3-4). Our attitudes and words matter. Jesus said,
35 “A good man out of the good treasure of his heart brings forth good things, and an evil man out of the evil treasure brings forth evil things. 36 But I say to you that for every idle word men may speak, they will give account of it in the day of judgment. 37 For by your words you will be justified, and by your words you will be condemned.” (Matt. 12:35-37).
All of these are sins that damage relationships and disrupt fellowship between believers. And Paul says, take them off, get rid of them, don’t wear these things anymore.
3. Why should we kill sin?
Paul not only tells us to kill sin and names examples of sins to kill, he also tells us why it is important for believers to kill sin.
A. Because of the wrath of God.
First, in Colossians 3:6, Paul says, “Because of these things the wrath of God is coming upon the sons of disobedience.” The Bible is clear. Those who practice these kinds of sins will not inherit the kingdom of God. Listen to what Paul writes in his other letters:
9 Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites, 10 nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God. (1 Cor. 6:9-10).
5 For this you know, that no fornicator, unclean person, nor covetous man, who is an idolater, has any inheritance in the kingdom of Christ and God. (Eph. 5:5).
19 Now the works of the flesh are evident, which are: adultery, fornication, uncleanness, lewdness, 20 idolatry, sorcery, hatred, contentions, jealousies, outbursts of wrath, selfish ambitions, dissensions, heresies, 21 envy, murders, drunkenness, revelries, and the like; of which I tell you beforehand, just as I also told you in time past, that those who practice such things will not inherit the kingdom of God. (Gal. 5:19-21).
And Revelation 21:8 tells their fate:
8 “But the cowardly, unbelieving, abominable, murderers, sexually immoral, sorcerers, idolaters, and all liars shall have their part in the lake which burns with fire and brimstone, which is the second death.” (Rev. 21:8).
We must put these sins to death because they are the cause of the outpouring of God’s righteous wrath for sin upon this world. God pours out the wrath of His judgment for sin against “the sons of disobedience.” As born-again children of God, we need not fear God’s wrath. Christ has taken away the wrath of God against us by His death on the cross. However, we should also not participate in those things which will provoke God’s wrath. God’s wrath is coming because of these things. So why would you want to participate in them?
Another reason to kill these sins is:
B. Because they belong to your old life.
Colossians 3:7 says that these are sins “in which you yourselves once walked when you lived in them.” Paul reminds those in Colossae of how they had changed. They used to walk in these ways. They used to live in immorality, impurity, passion, evil desire, and greed. That was their old life before Christ.
In Romans 6, Paul writes,
21 What fruit did you have then in the things of which you are now ashamed? For the end of those things is death. 22 But now having been set free from sin, and having become slaves of God, you have your fruit to holiness, and the end, everlasting life. 23 For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord. (Rom. 6:21-23).
Those sins only brought slavery and death. But Christ brought holiness and eternal life. You already said goodbye to your old way of life, why would you welcome these things back into your life?
In Colossians 3:9-10 we see the third reason:
C. Because God is making you new.
9 Do not lie to one another, since you have put off the old man with his deeds, 10 and have put on the new man who is renewed in knowledge according to the image of Him who created him, (Col. 3:9-10).
Paul says that you’ve already changed clothes, you’ve put off the old man and put on the new man. Why would you pick up your old filthy rags and put them on over your new holy robes? We kill sin in our life because we are already clothed in the righteousness of Christ. We are made new “according to the image of Him who created” us.
We have already learned in Colossians what Christ has done for us. God has ” delivered us from the power of darkness and conveyed us into the kingdom of the Son of His love” (Col. 1:13). In Christ, “we have redemption through His blood, the forgiveness of sins” (Col. 1:14). God in Christ “has reconciled” us “in the body of His flesh through death” (Col. 1:21-22). We died with Christ and were “raised with Him through faith in the working of God” (Col. 2:12). In Christ, we have been made complete (Col. 2:10). Our “life is hidden with Christ in God” (Col. 3:3). Our new man is “renewed in [this] knowledge” (Col. 3:10). We, who have died with Christ and been raised with Him should make every effort to kill our sin.
D. Because Christ is all and in all.
Colossians 3:11 says that we are in Christ “where there is neither Greek nor Jew, circumcised nor uncircumcised, barbarian, Scythian, slave nor free, but Christ is all and in all.” The new self in Christ is not just the transformation of the individual but also of our relationships with each other. It’s not just doing away with sinful patterns or habits but also with the man-made barriers that divide us. In Christ, all the man-made barriers of race, religion, culture, and social class have been removed between believers.
“Christ is all” means Christ is all that matters. “Christ is … in all” means that Christ dwells by His Spirit in each every believer, so how can you sin against them in attitude, words, or actions? Christ is central, and in Christ all the sinful man-made barriers have been removed.
What is the Christian’s attitude to sin? Get rid of it! You died with Christ; you have been raised with Christ; now Christ tells you to get rid of the sinful things in your life. So off with the old, on with the new! Be killing sin, or it will be killing you.
As we come to the Lord’s Table today, has the Lord spoken to you about sins that are still residing in your members? Are some of these attitudes still clinging to your heart? Do they sometimes come out of your mouth? Take time right now as we sing a hymn to kill any residing sin. You died with Christ to sin, so kill any sin that remains in your flesh.
