Faith, love and hope, and each one doing work
The letter opens with a phrase that fixes its whole shape. Paul thanks God for 'your work of faith and labor of love and patience of hope in our Lord Jesus Christ' (1:3). Each of the three has a verb attached. Faith works, love labors, and hope holds out under strain. That third one carries the letter, because hope in this congregation was under pressure from two sides at once, from persecution outside and from bereavement inside. Paul returns to the same three at 5:8, where they become armor: 'putting on the breastplate of faith and love; and for a helmet, the hope of salvation' (5:8). What the church did with the three is stated in one sentence about their conversion: they 'turned unto God from idols, to serve a living and true God' (1:9), 'and to wait for his Son from heaven' (1:10). Turning, serving and waiting are the whole Christian life in this letter.

The gospel arrived in power and in the Holy Spirit
Paul describes what happened when he preached in Thessalonica in terms that go past persuasion. 'our gospel came not unto you in word only, but also in power, and in the Holy Spirit, and in much assurance' (1:5). The converts received it the same way, 'having received the word in much affliction, with joy of the Holy Spirit' (1:6), and joy under affliction is itself credited to the Spirit. Paul says the word kept working after he left: they 'accepted it not as the word of men, but, as it is in truth, the word of God, which also worketh in you that believe' (2:13). The Spirit is named as a present giver at 4:8, where God 'giveth his Holy Spirit unto you' in the present tense, and as a present speaker at 5:19-20. A church three months old is described as having power, joy, assurance and prophecy among it, and Paul treats none of that as unusual.

Ministry described from the inside
Chapter 2 is the fullest account Paul ever gives of how he conducted a mission, and he gives it because something was being said about him after he left. He names the charges by denying them one at a time. There was no error, uncleanness or guile in the message (2:3). There were no 'words of flattery' and no 'cloak of covetousness' (2:5). There was no hunt for reputation, 'nor seeking glory of men, neither from you nor from others, when we might have claimed authority as apostles of Christ' (2:6). Then he gives the two family pictures that have stayed with readers ever since: 'we were gentle in the midst of you, as when a nurse cherisheth her own children' (2:7), and 'as a father with his own children, exhorting you, and encouraging you, and testifying' (2:11). The support for all of it is a fact anyone in the city could check, that the missionaries paid their own way: 'working night and day, that we might not burden any of you, we preached unto you the gospel of God' (2:9).

Sanctification named as the will of God
Paul answers the question of what God wants with a single noun. 'For this is the will of God, even your sanctification, that ye abstain from fornication' (4:3). The instruction that follows is concrete, that each man 'know how to possess himself of his own vessel in sanctification and honor' (4:4), and it comes with a warning that the matter is not private, 'because the Lord is an avenger in all these things' (4:6). Then the ground: 'For God called us not for uncleanness, but in sanctification' (4:7), and the one who is refused when the teaching is refused is named, 'he that rejecteth, rejecteth not man, but God, who giveth his Holy Spirit unto you' (4:8). The same word closes the letter as a prayer: 'And the God of peace himself sanctify you wholly' (5:23), followed by the promise that carries it, 'Faithful is he that calleth you, who will also do it' (5:24). Sanctification is commanded and it is also given.

The dead in Christ, and the grief that has an answer
Members of the congregation had died, and the church was grieving as though those believers had missed what was coming. Paul writes the passage to end that. 'But we would not have you ignorant, brethren, concerning them that fall asleep; that ye sorrow not, even as the rest, who have no hope' (4:13). Sleep is his word for the body of a believer, and the ground for using it is the resurrection of Jesus: 'For if we believe that Jesus died and rose again, even so them also that are fallen asleep in Jesus will God bring with him' (4:14). Then the order of events, given on authority Paul says he received: 'For the Lord himself shall descend from heaven, with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first' (4:16), 'then we that are alive, that are left, shall together with them be caught up in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord' (4:17). The living do not go ahead of the dead. The dead go first, and everyone arrives together. Paul states the purpose of the whole paragraph in the next line: 'Wherefore comfort one another with these words' (4:18).

Sons of the day, in a night that ends
Chapter 5 takes up timing and answers it by changing the subject from dates to identity. 'For yourselves know perfectly that the day of the Lord so cometh as a thief in the night' (5:2), and the surprise falls on people at ease: 'When they are saying, Peace and safety, then sudden destruction cometh upon them' (5:3). Then the turn: 'But ye, brethren, are not in darkness, that that day should overtake you as a thief' (5:4), 'for ye are all sons of light, and sons of the day' (5:5). The thief image is about who is asleep rather than about the calendar, so the practical conclusion is watchfulness and sobriety (5:6). The paragraph ends on the strongest promise in the letter, 'For God appointed us not unto wrath, but unto the obtaining of salvation through our Lord Jesus Christ' (5:9), and on a line that covers both the dead and the living Paul has just described, 'whether we wake or sleep, we should live together with him' (5:10).

Keep the fire, and test what is spoken
The closing instructions run in short commands, and three of them govern how a congregation handles the Spirit. 'Quench not the Spirit' (5:19) uses the ordinary verb for putting out a fire, so the picture is a flame that a church can smother by its own conduct. 'despise not prophesyings' (5:20) forbids treating what is spoken as beneath attention. Then the safeguard that makes the first two workable: 'prove all things; hold fast that which is good' (5:21), with the verb Greek used for assaying metal, followed by 'abstain from every form of evil' (5:22). The three belong together. A church that tests nothing will be burned by counterfeits, and a church that despises prophecy has nothing to test. Paul gives the same congregation a settled leadership to respect in the same paragraph, 'them that labor among you, and are over you in the Lord, and admonish you' (5:12), so the openness is exercised inside an ordered church rather than against it. This site reads the commands as standing on churches now, in the plain sense Paul wrote them.
