2 Thessalonians 1:1-5

V1-5 – ¹Paul, Silas [or Silvanus] and Timothy, To the church of the Thessalonians in God our Father and the Lord Jesus Christ: Grace and peace to you from God the Father and the Lord Jesus Christ. ³We ought always to thank God for you, brothers, and rightly so, because your faith is growing more and more, and the love every one of you has for each other is increasing. ⁴Therefore, among God’s churches we boast about your perseverance and faith in all the persecutions and trials you are enduring. ⁵All this is evidence that God’s judgment is right, and as a result you will be counted worthy of the kingdom of God, for which you are suffering.

Paul begins with a nearly identical introduction as that of 1 Thessalonians. He still stresses the intimacy of Father and Son and adds that grace and peace extends to believers from both. This letter is so similar to 1 Thessalonians, and written so soon after the first letter, that we could call it a supplement or extension to Paul’s first correspondence with the Thessalonians. Paul thanks God for – and even boasts before other churches about – them, specifically because God is growing their faith, as seen worked out in their increasing love for one another, during ongoing, and perhaps increasing, “persecutions and trials” (v3-4). Calvin says, “When [Paul] gives thanks to God on this account, he declares that the enlargements, no less than the beginnings, of faith and love are from Him, for if they proceeded from the power of men, thanksgiving would be pretended, or at least worthless.” And we also infer that if the Thessalonians had fallen away as a result of persecution, then the persecution would have stopped (Galatians 5:11); but they have persevered and grown more faithful, evidence that “God’s judgment is right” and that they “will be counted worthy of the kingdom of God” (v5). We’ll look at God’s right judgment in a minute, but first consider worthiness.

As Paul speaks of being “counted worthy” of God’s kingdom here, we must consider where he speaks of worthiness elsewhere as well, being worthy of God Himself (1 Thessalonians 2:12), of God’s calling (2 Thessalonians 1:11; Ephesians 4:1), of the Lord (Colossians 1:10), and of the gospel (Philippians 1:27-28). A worthy life is, as the footnote of my Reformation Study Bible declares, one of “patient, joyful discipleship even in the face of life-threatening abuse from those hostile to the faith. Such lives are sure evidence that God’s judgment is right. Even while enjoying the benefits of citizenship in the heavenly kingdom, Christians still must suffer for its sake (Acts 14:22), since the kingdom will inevitably confront diabolical opposition.”

1 Thessalonians 5:16-28

V16-28 – ¹⁶Be joyful always; ¹⁷pray continually; ¹⁸give thanks in all circumstances, for this is God’s will for you in Christ Jesus. ¹⁹Do not put out the Spirit’s fire; ²⁰do not treat prophecies with contempt. ²¹Test everything. Hold on to the good. ²²Avoid every kind of evil. ²³May God Himself, the God of peace, sanctify you through and through. May your whole spirit, soul and body be kept blameless at the coming of our Lord Jesus Christ. ²⁴The one who calls you is faithful and he will do it. ²⁵Brothers, pray for us. ²⁶Greet all the brothers with a holy kiss. ²⁷I charge you before the Lord to have this letter read to all the brothers. ²⁸The grace of our Lord Jesus Christ be with you.

Paul wraps up with a series of short commands The first three, “be joyful always; pray continually; give thanks in all circumstances,” are explained as “God’s will for you in Christ Jesus.” These are not merely attitudes to have, but commands to do. We are to always be joyful (Philippians 4:4); that’s hard for me, as somewhat of a pessimist, but it is evidenced by constancy in prayer. We are to always pray; this command does not mean to pray instead of eat, or pray instead of sleep, or pray instead of read. Nor does it mean that we are merely to maintain a prayerful attitude. Rather, we are to pray often – continually, Paul says. We are never to exclude prayer from our lives for any reason. When the Spirit prompts, we are to pray. I can think of many times that I have felt prompted to pray, especially aloud, yet refused out of convenience or peer pressure or fear of what others – even my spouse or children – might think. How foolish! And as a check against what might often be foolish desires that we pray for, we are also to give thanks in all things, whether good or bad experiences take place in our lives.

The importance of v19-22 is that legitimate prophecy must be tested and not treated “with contempt,” which would be one way to “put out the Spirit’s fire.” Calvin warns, “Those…who infer from this that it is in man’s option either to quench or to cherish the light that is presented to him, so that they detract from the efficacy of grace, and extol the powers of free will, reason on false grounds. For although God works efficaciously in His elect, and does not merely present the light to them, but causes them to see, opens the eyes of their heart, and keeps them open, yet as the flesh is always inclined to indolence, it has need of being stirred up by exhortations. But what God commands by Paul’s mouth, He himself accomplishes inwardly. In the mean time, it is our part to ask from the Lord, that He would furnish oil to the lamps which He has lighted up, that He may keep the wick pure, and may even increase it.”

Paul’s teaching here refutes the unbiblical idea of cessationism, which declares that the spiritual gifts, especially prophecy and tongues, have ceased. The goal of cessationist thought is to promote the completion of Scripture, out of fear that a true prophecy may be uttered that contradicts God’s word, or more commonly out of denial that a false prophet could utter a false prophecy but think it to be true and lead others astray. But needless to say, that can’t happen, for we deny that true believers can be led permanently astray. And furthermore, what would we be able to test that prophecy against? We test prophecy against Scripture to confirm its truth, or to reject it upon failure to agree with Scripture. If the content of a given prophecy cannot be tested against Scripture, then we are to ignore it. By the power of the indwelling Holy Spirit, we are to “hold on to the good” and “avoid every kind of evil.” But we ought also to consider with Calvin that “prophecy,” often thought to refer to telling the future, may very well simply suggest the important gift of interpreting the Scripture (1 Corinthians 14:3), preaching or expounding God’s word for application to any given audience. Obviously, this gift should not be treated with contempt, or despised, but tested. Yet today, many professing Christians do indeed despise preaching.

A recurring theme throughout this epistle, sanctification is mentioned again in v23. Paul speaks of sanctification being complete – our “whole spirit, soul, and body” (Hebrews 4:12; cf. Mark 12:30; Isaiah 26:9). It will be completed at Jesus’ second coming and not until then. And sanctification is certain, because God, faithful, is the One who does it in us (v24). Normally, the soul is deemed to consist of the mind, the will, and emotions. Animals exhibit these functions. But the spirit is unique to humanity.

Cheung summaries this section saying, “Three things receive emphasis in v23-24. First, God sanctifies His people in a thorough manner, even ‘through and through.’ Second, Paul emphasizes that God is the one who sanctifies, and makes His people blameless. Third, he says that God is not only able to do this, but He is faithful to do it.” And Calvin concludes, “We know, however, that under the term sanctification is included the entire renovation of the man. The Thessalonians, it is true, had been in part renewed, but Paul desires that God would perfect what is remaining. From this we infer, that we must, during our whole life, make progress in the pursuit of holiness. But if it is the part of God to renew the whole man, there is nothing left for free will. For if it had been our part to co-operate with God, Paul would have spoken thus – ‘May God aid or promote your sanctification.’ But when he says, sanctify you wholly, he makes Him the sole Author of the entire work… Our calling ought to be held by us as an evidence of everlasting grace, for [God] will not leave the work of His hands incomplete (Psalm 138:8). Paul…addresses believers, who had not been merely called by outward preaching, but had been effectually brought by Christ to the Father, that they might be of the number of His sons.”

Finally, Paul “charges you before the Lord.” This is an unusually strong Greek verb. Paul is effectively putting the Thessalonians under an oath that they must teach the contents of this letter to all the Christians in their sphere of influence. Paul knew his teaching was good and important, and more importantly, from God (see 1 Thessalonians 4:8). Cheung concludes his commentary on 1 Thessalonians by saying, “Christians are at times driven to discouragement, and sometimes almost to despair, when they perceive that they fall short of perfection. Paul’s doctrine of sanctification reminds us to place our confidence in God, and not in ourselves. This does not excuse us from our responsibilities, since Paul has just finished listing a number of them. It is not that we may become passive in the pursuit of holiness, but that even our efforts are inspired and energized by God, and that we may have confidence in Him to do this for us. As Paul writes elsewhere, ‘Therefore, my dear friends, as you have always obeyed – not only in my presence, but now much more in my absence – continue to work out your salvation with fear and trembling, for it is God who works in you to will and to act according to His good purpose’ (Philippians 2:12-13).”

1 Thessalonians 5:12-15

V12-15 – ¹²Now we ask you, brothers, to respect those who work hard among you, who are over you in the Lord and who admonish you. ¹³Hold them in the highest regard in love because of their work. Live in peace with each other. ¹⁴And we urge you, brothers, warn those who are idle, encourage the timid, help the weak, be patient with everyone. ¹⁵Make sure that nobody pays back wrong for wrong, but always try to be kind to each other and to everyone else.

Vincent Cheung opens his commentary on this passage by saying, “V12-15 provide instructions that are necessary to maintain the strength of a congregation’s internal stability as well as its testimony before the world. Paul here refers to the church leaders, the believers, and ‘everyone else.’” He asks the Thessalonian brothers to “respect those who work hard among you, who are over you in the Lord and who admonish you.” Paul must have set up a church leadership hierarchy during his brief stay in Thessalonica, such that he probably refers here to elders and other leaders. Perhaps Jason and Aristarchus may have been in view. They are to be respected, loved, since they “work hard,” and they are to be held “in the highest regard in love because of their work.” Calvin notes, “This work is the edification of the Church, the everlasting salvation of souls, the restoration of the world, and, in fine, the kingdom of God and Christ. The excellence and dignity of this work are inestimable: hence those whom God makes ministers in connection with so great a matter, ought to be held by us in great esteem.”

In v13b, Paul says to “live in peace with each other.” He most certainly has in mind Christian unity here, especially between pastors and laymen. Cheung says, “Believers consist of individuals from different nations, races, genders, and social, financial, and educational backgrounds. When they come together, these differences are not obliterated. When unbelievers are able to maintain unity among themselves, it is because they celebrate their differences and practice tolerance. The basis for this unity is common humanity. In contrast, when believers come together in unity, they practice reconciliation. The basis for this true unity is common faith in Christ… Our peace is not one that tolerates incompatible principles and practices, but it is one that confronts them and demands their conformity to Christ. Paul tells his converts to ‘warn those who are idle.’ We are to disapprove, entreat, reprimand, and even threaten those who do wrong. The basis for this is not the inherent superiority, the strong opinion, or even the mere assertiveness of some believers over others, but it is the authority of Christ, to whom all are accountable. On this same basis, we are to ‘encourage the timid, help the weak, be patient with everyone.’”

V14 and following refer to the entire congregation, not just the leadership. We know from this passage (and 2 Thessalonians 3:6-7,11) that idleness was a problem in Thessalonica. It is thought that because these Christians thought Christ’s return to be imminent, they stopped working. Paul’s instruction is to sharply reprove (“warn”) them. For the timid, Paul commands encouragement; the weak need help, Paul says; and all of the congregation members need patience.

There are two final commands in v15 – not to seek revenge and to show kindness. Christians ought to seek justice, but not personal retaliation. Elsewhere, Paul quotes the Lord as saying, “Vengeance is Mine, I will repay” (Deuteronomy 32:35; Romans 12:19-21; Hebrews 10:30). And Paul will elaborate on the justice of God’s revenge – He is the avenger – in 2 Thessalonians 1:6-8.

1 Thessalonians 5:6-11

V6-11 – ⁶So then, let us not be like others, who are asleep, but let us be alert and self-controlled. ⁷For those who sleep, sleep at night, and those who get drunk, get drunk at night. ⁸But since we belong to the day, let us be self-controlled, putting on faith and love as a breastplate, and the hope of salvation as a helmet. ⁹For God did not appoint us to suffer wrath but to receive salvation through our Lord Jesus Christ. ¹⁰He died for us so that, whether we are awake or asleep, we may live together with Him. ¹¹Therefore encourage one another and build each other up, just as in fact you are doing.

Paul has given eschatological doctrine, and he has explained it in more detail. Now he lays out how we ought to respond to his teaching. Paul preaches that we believers are not to be like unbelievers. “Don’t be like the people who don’t believe in Jesus.” How often do we hear that from the pulpit in church? Probably not enough… Since we are “sons of the light and sons of the day” (v5), we ought to “be alert and self-controlled” (v6), “putting on faith and love as a breastplate, and the hope of salvation as a helmet” (v8, cf. Ephesians 6:13-18). The call is to wake up, stay alert, and go to war! Calvin comments, “The life of Christians is like a perpetual warfare, inasmuch as Satan does not cease to trouble and molest them. [Paul] would have us, therefore, be diligently prepared and on the alert for resistance: farther, he admonishes us that we have need of arms, because unless we be well armed we cannot withstand so powerful and so strong an enemy.”

Paul notes in v9 that believers need not fear “the day of the Lord,” or “Judgment Day,” because “God did not appoint us to suffer wrath (Romans 9:16-24), but to receive salvation through our Lord Jesus Christ” (Acts 13:48; John 5:24). Cheung concludes, “We are not taken by surprise because we are spiritually and morally ready for God to come and act in judgment. This is a superior kind of readiness. If we do not become spiritually prepared to meet Him, it would still be useless to know the time. His coming would only bring judgment upon us. But if we remain in a constant state of moral readiness, then we do not need to know the time of judgment – He will find us steadfast in our faith and labor when He comes.” We’ll have more to say about eschatological matters when we come to 2 Thessalonians 2, but for now, we conclude by noting the closing exhortation – continue to “encourage one another and build each other up” (v11).
