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
Paul’s overwhelming desire to see the Thessalonian believers face-to-face was about more than a chance to reconnect and get reacquainted with old friends. Paul had something far more important in mind. As he told them in the previous section of his letter, the motivation behind his desire to see them again was that he “might supply what is lacking in your faith” (1 Thessalonians 3:10 ESV). The reason he had sent Timothy to Thessalonica was “to establish and exhort” them in their faith (1 Thessalonians 3:2 ESV).
And while Paul has confessed that Timothy’s good news regarding their faith and love brought him comfort, he still felt the pressing need to see them so that he might “fill in the gaps” of their faith (1 Thessalonians 3:10 NLT).
Paul’s deep love for these people seems quite obvious. He had a pastor’s heart that cared for their spiritual well-being. While their faith was strong, even in the midst of trying circumstances, Paul knew that there was much they needed to know if they were going to remain strong in the days ahead. The battle was far from over because the enemy had not thrown in the towel. The opposition had not given up its efforts to demoralize the sheep and discredit the shepherd.
So, Paul felt compelled to share with them one final word of counsel. He complimented them on their faith and love and described them as “standing fast in the Lord” (1 Thessalonians 3:8 ESV). But there is one more thing they needed to hear him say.
…we ask and urge you in the Lord Jesus, that as you received from us how you ought to walk and to please God. – 1 Thessalonians 4:1 ESV
Paul was not admonishing them or demanding that they correct their sinful behavior. In fact, he added the statement, “…just as you are doing” (1 Thessalonians 4:1 ESV). They were already living in a way that pleased God, but Paul wants them to know that they were going to need to do so “more and more” (1 Thessalonians 4:1 ESV).
In the short time Paul and Silas had spent in Thessalonica, they had instructed them how to live their lives in a way that was pleasing to God. To get his point across, Paul used the Greek word peripateo, which is translated as “walk.” It was one of Paul’s favorite terms that could be used to refer to the physical act of walking, but he used it as a metaphor for spiritual life. When he used the term “walk,” he was referring to the daily conduct of one’s life. In those days, walking was the primary mode of transportation for the average person. You couldn’t conduct your life without walking. So, Paul used this normal means of mobility as an analogy for living the Christian life, and he used it often.
…who walk (peripateo) not according to the flesh but according to the Spirit… – Romans 8:4 ESV
Let us walk (peripateo) properly as in the daytime, not in orgies and drunkenness, not in sexual immorality and sensuality, not in quarreling and jealousy. – Romans 13:13 ESV
Only let each person lead the life (peripateo) that the Lord has assigned to him, and to which God has called him. – 1 Corinthians 7:17 ESV
I therefore, a prisoner for the Lord, urge you to walk (peripateo) in a manner worthy of the calling to which you have been called… – Ephesians 4:1 ESV
…walk (peripateo) in a manner worthy of the Lord, fully pleasing to him. – Colossians 1:10 ESV
As followers of Christ, their spiritual walk or manner of life was to be distinctively different than that of their lost friends and family members. They were to live set-apart lives, marked by holiness and righteousness. But their spirituality was never meant to remain in a static state. Salvation was never intended to be a one-time event but was to be an ongoing, regularly occurring, and lifelong transformational process. The apostle Peter referred to it as growing up in salvation (1 Peter 2:2). Paul told the Ephesians believers to “grow up in every way into him [Christ]” (Ephesians 4:15 ESV).
There is no place for complacency in the Christian life. At no point are we to become satisfied with the status quo. We are not the ones who get to determine whether we have successively achieved spiritual maturity, and Paul makes that point perfectly clear to his brothers and sisters in Thessalonica.
For this is the will of God, your sanctification… – 1 Thessalonians 4:3 ESV
Paul put it in blunt terms. What God wanted of them and for them was simple: Their sanctification. But what did he mean by this? The Greek word he used is hagiasmos, and it can be translated as “holiness.” It derives from another Greek word, hagiazo, which means “to separate from profane things and dedicate to God.” To be holy is to be set apart or consecrated for a specific purpose. In the case of a believer, they are set apart to God. So, to be sanctified is the process of being constantly and consistently set apart for God’s use. It involves a separation from all that is ungodly or unrighteous. Or as Paul liked to put it, it involves putting off the old and putting on the new.
…put off your old self, which belongs to your former manner of life and is corrupt through deceitful desires…put on the new self, created after the likeness of God in true righteousness and holiness. – Ephesians 4:22, 24 ESV
Just a few verses earlier in his letter to the Ephesian believers, Paul challenged them, “You must no longer walk as the Gentiles do…” (Ephesians 4:17 ESV). They were not to conduct their lives in the same way they had before. In fact, in chapter two of Ephesians, Paul points out the stark difference between their new life in Christ and that of their old, pre-salvation nature.
…you were dead in the trespasses and sins in which you once walked (peripateo), following the course of this world, following the prince of the power of the air, the spirit that is now at work in the sons of disobedience— among whom we all once lived in the passions of our flesh, carrying out the desires of the body and the mind, and were by nature children of wrath, like the rest of mankind. – Ephesians 2:2-3 ESV
But Paul stressed the change that had taken place in their lives.
But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved… – Ephesians 2:4-5 ESV
The lives of the Ephesians believers had been radically changed when they placed their faith in Christ. The same thing was true of the believers in Thessalonica, and that change was to be tangible and visible. It was to show up in their behavior and every facet of their daily lives. Just to make sure they understood the non-negotiable and all-pervasive nature of this change, Paul provided them with the details.
God’s will is for you to be holy, so 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. – 1 Thessalonians 4:3-5 NLT
There was to be no compromising of their faith. Their new life in Christ left no room for old habits and attitudes. Paul told the Corinthian believers, “Anyone who belongs to Christ has become a new person. The old life is gone; a new life has begun!” (2 Corinthians 5:17 NLT).
The old adage, “something old, something new,” has no place in the life of the believer. God expects and demands life transformation and has provided His Holy Spirit to make it possible. A life marked by sexual sin and immorality was unacceptable for the Christ-follower; it violated the will of God and failed to model a life of holiness. In the Greek culture of that day, sexual promiscuity was an accepted way of life. Demosthenes, a Greek statesman and orator, wrote, “We keep prostitutes for pleasure; we keep mistresses for the day-to-day needs of the body; we keep wives for the begetting of children and for the faithful guardianship of our homes.”
In a culture marked by self-indulgence and the willful gratification of all sexual desires, the Christian was to live in a way that distinguished them as having been set apart or consecrated to God — separated from the profane and dedicated to His glory. To do so demands self-control. They would need to control their physical passions and desires, choosing instead to “live in holiness and honor—not in lustful passion like the pagans who do not know God and his ways” (1 Thessalonians 4:4-5 ESV).
Once again, Paul puts his thoughts in simple, easy-to-understand terms: “God has called us to live holy lives, not impure lives” (1 Thessalonians 4:7 NLT). Not a lot of wiggle room there. Paul doesn’t leave it open for negotiation or debate. God’s will was their sanctification. His expectation was holiness, not impurity. He was interested in set-apartness, not sameness. Anyone who rejected this idea was not rejecting the teachings of Paul; they were disobeying and, ultimately, denying the will of God Almighty.
Therefore whoever disregards this, disregards not man but God, who gives his Holy Spirit to you. – 1 Thessalonians 4:8 ESV
Paul was teaching the need to live an ongoing life of transformation. The Thessalonian believers were to walk and please God more and more. There was to be no end to their spiritual journey. At no point were they to assume they had arrived. Salvation was to result in ongoing sanctification, a never-ending, Spirit-empowered conformity to the image of Christ — for a lifetime. No, for eternity.
Father, the call to holiness sounds so unachievable. We still live in a fallen world and do battle with our sinful natures every day. I get it that You want us to live holy lives and I understand that Your Spirit provides us with all the power we need for life and godliness (2 Peter 1:3). But it still seems so impossible. Even Jesus said, “The spirit is willing, but the body is weak!” (Matthew 26:41 NLT). And the apostle Paul admitted his own struggle with sin when he wrote, “I want to do what is right, but I can’t. I want to do what is good, but I don’t. I don’t want to do what is wrong, but I do it anyway” (Romans 7:18-19 NLT). But I know You would not call us to live holy lives if You didn’t have a way to make it possible. I have seen you transform my life through the power of the Spirit and the application of Your Word. I am not the man I once was and I know I am not yet the man You intend me to be. I am a work in process, and, one day, You will finish what You began by fully transforming me into the likeness of Your Son. In the meantime, help me to stay strong, to remain committed, and to recognize my inability to change myself. My sanctification is Your job, not mine. You are the one who saved me and You alone can sanctify me. But I have to cooperate and make Your will my own. Amen.
