1 Finally, then, brothers, we ask and urge you in the Lord Jesus, that as you received from us how you ought to walk and to please God, just as you are doing, that you do so more and more. 2 For you know what instructions we gave you through the Lord Jesus. 3 For this is the will of God, your sanctification: that you abstain from sexual immorality; 4 that each one of you know how to control his own body in holiness and honor, 5 not in the passion of lust like the Gentiles who do not know God; 6 that no one transgress and wrong his brother in this matter, because the Lord is an avenger in all these things, as we told you beforehand and solemnly warned you. 7 For God has not called us for impurity, but in holiness. 8 Therefore whoever disregards this, disregards not man but God, who gives his Holy Spirit to you. – 1 Thessalonians 4:1-8 ESV
The chapter and verse designations found in our English translations were not In the original letter sent by Paul to the Thessalonians. So, the rather abrupt break we find between the close of chapter 3 and the beginning of chapter four would not have been there. And that artificially imposed structure on the letter can cause some unnecessary confusion when trying to determine Paul’s intent and meaning.
Chapter three ends with Paul expressing his strong desire that God increase the love of Thessalonian believers for one another and for those outside their fellowship. And his prayer is that God would “establish your hearts blameless in holiness before our God and Father, at the coming of our Lord Jesus with all his saints” (1 Thessalonians 3:13 ESV). Paul’s concern is that they live loves marked by love and godliness. He longs to see their inner heart transformation manifest itself through external expressions that give evidence to their holiness.
And Paul carries that thought into the next paragraph. The word “finally” is translated from the Greek word loipon, which can have a wide range of meanings, depending upon the context. It could be translated, “in addition” or “moreover.” Paul is expanding on what he has just said. He’s adding to his thoughts by providing his readers with further counsel regarding the link between their status as believers in Jesus Christ and the behavior that marks their lives. Paul had previously provided them with instructions in how “to walk and to please God,” and he commends them for having done so. But he also encourages them to “do so more and more” (1 Thessalonians 4:1 ESV). They were not to grow complacent or content. This was no time to rest on their laurels or to become satisfied with the current condition of their spiritual lives.
And it must be noted how Paul weaves together two very important aspects regarding the Christian’s spiritual maturity. At the close of chapter three, he expressed his firm belief that it was God alone who could increase the level of their love and cause it to overflow. And only God could make their hearts strong, blameless, and holy. The inner transformation of their lives was totally dependent upon divine power, not human effort. It was impossible for them to manufacture, through human means, the kind of love God demanded. There is no way that they could repair the sin-damaged condition of their own hearts through self-renovation. Man is incapable of seeing the true state of his inner life. As the prophet Jeremiah put it, “The human heart is the most deceitful of all things, and desperately wicked. Who really knows how bad it is?” (Jeremiah 17:9 NLT). And even if he could see how wicked his heart is, man is powerless to do anything about it. That’s the meaning behind a comment made by God regarding the people of Judah and recorded in the book of Jeremiah.
“Can an Ethiopian change the color of his skin? Can a leopard take away its spots? Neither can you start doing good, for you have always done evil.” – Jeremiah 13:23 NLT
God asked two rhetorical questions that shared the same obvious answer: No. The people of God were powerless to change their behavior because they couldn’t change their hearts. Their actions were nothing more than an outer expression of their inner condition.
So, Paul reminds the Thessalonian believers that it is the power of God that has transformed them and made them His children. Their newfound status as sons and daughters of God was His doing. But that didn’t mean God was finished with them. Otherwise, Paul would not have prayed for God to increase their love to make their hearts strong, blameless, and holy. They were works in process. Which is what Paul meant when he wrote to the believers in Philippi:
God, who began the good work within you, will continue his work until it is finally finished on the day when Christ Jesus returns. – Philippians 1:6 NLT
But Paul’s reference to God’s work in them doesn’t mean that God expects no work from them. And he makes that point perfectly clear when he states, “this is the will of God, your sanctification” (1 Thessalonians 4:3 ESV). This little verse packs a punch and yet is easily overlooked or ignored by most Christians. It provides a remarkable glimpse into God’s divine will for the life of the believer, and it is all summed up in the one word, sanctification.
The Greek word Paul used is hagiasmos and, like most Greek words, it is rich in meaning. It is sometimes translated as holiness, consecration, and purification. And it can be used to signify a position (a holy nation) and a process (be holy). In his letter to the church in Corinth, Paul provides them with a list that describes the unrighteous, or those outside of Christ. It includes the sexually immoral, idolaters, adulterers, men who practice homosexuality, thieves, the greedy, drunkards, revilers, and swindlers. Then Paul makes an interesting statement.
…such were some of you. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God. – 1 Corinthians 6:11 ESV
Notice that he lists the Corinthian believers as having been sanctified. In this case, he is referring to their having been set apart by God. In the process of their salvation, their sinful condition was cleansed by the righteous blood of Christ, making them pure and acceptable before God and able to be set apart for His use. Like the utensils used in temple worship, they had to be cleansed and purified before they could be deemed worthy of use for God. Which is what Peter meant when he wrote:
…you are a chosen people. You are royal priests, a holy [hagios] nation, God’s very own possession. – 1 Peter 2:9 NLT
Don’t miss what Peter is saying. He tells his readers that they are a holy nation. They have been chosen by God and set apart as His very own possession. They belong to Him. Which is exactly what Paul told the believers in Corinth.
You do not belong to yourself, for God bought you with a high price. So you must honor God with your body. – 1 Corinthians 6:19-20 NLT
They had been declared holy by God and set apart for His use. Which meant that they were to honor God with the entirety of their lives. And that is the whole point behind Paul’s admonitions to the believers in Thessalonica and Corinth. Notice the similarities between his comments in the two letters.
He tells the Thessalonians, “stay away from all sexual sin. Then each of you will control his own body and live in holiness and honor—not in lustful passion like the pagans who do not know God and his ways” (Thessalonians 4:3-5 NLT). And his words to the Corinthians were similar.
Run from sexual sin! No other sin so clearly affects the body as this one does. For sexual immorality is a sin against your own body. Don’t you realize that your body is the temple of the Holy Spirit, who lives in you and was given to you by God? – 1 Corinthians 18-19 NLT
In a sense, Paul is commanding both groups to live their lives in a manner that matches their calling. They have been set apart by God for His use, and their lives were to reflect it. They were not free to live according to their own desires anymore. They had been bought with a price and belonged to God. And it was His will that they live sanctified, set apart lives.
And, as it to make sure the don’t miss his point, Paul states, “God has not called us for impurity, but in holiness” (1 Thessalonians 4:7 ESV). There’s that Greek word, hagiasmos again. It is the very same word that is translated as “sanctification” in verse 3. Paul is emphasizing that the believer’s calling by God is for the purpose of holiness or sanctification, not impurity.
There is a very important truth revealed in this verse that is easily overlooked and underappreciated. Paul says that God has not called us for impurity but in holiness. Those two prepositions are critical. The first one conveys a destination or activity. The second has to do with status or position. Holiness is not to be viewed as a process, but a positional reality. Holiness or sanctification is not to be viewed as a progression towards something as much as a revelation of something. We are already holy in God’s eyes. So, we are to live as what we are. We have been set apart by God in holiness. That is our new status or condition. We have been set apart by God for His will.
But there is going to be a constant war between our will and that of God. And one of the areas of life where the battle will rage the hottest is in regards to sexual sin. It was obviously a problem among the Thessalonian believers, or Paul would not have addressed it. While they enjoyed status as sanctified saints, they were going to have to live lives that gave evidence of who there were. And Paul reminds them that they had the indwelling power of the Spirit of God available to them. This was not about will power and self-effort. But it was about a willingness to make God’s will for them their highest priority. And Paul minces no words when he tells them, “this is the will of God, your sanctification.”
