To show that since the coming of the Lord is a certain event those who are born again will not be surprised at that coming, but will be prepared and ready, by being prepared by God for that great day.
INTRODUCTION:
In the last chapter, the final six verses, we saw the blessing of being in Christ, whether we are alive at His coming or dead.
It is exciting thinking of our Lord’s certain return. There may be many who name the name of Jesus, but call this teaching myth, or someones wild imagination run wild. Jesus, our Savior said that He was returning or “I will come again…” (John 14:3). If He lied about this how can we trust Him for salvation; because this event is a part of our redemption/salvation. We would not be able to trust Him if He does not return. His coming again is further evidence of His bodily resurrection; especially when He raises those who have died as His followers. The only way He would not return is if He did not rise bodily from the grave. He will come again, just as He said.
In this chapter, and the final chapter of Second Thessalonians we find more encouragement for the born again child of God, but it is also a warning to those who do not know Jesus. Verses 1 – 11 tell us of the “Day of the Lord”. The “Day of the Lord” is also mentioned in the Old Testament books of Joel 2:1, 2ff.; Amos 5:18-20; Zephaniah 1:14-18; Isaiah 2:12-21. It is also called “The time of Jacob’s trouble” in Jeremiah 30:7. This is a day of darkess for the reprobate, unbelievers alive in that day. A day of struggle, catastrophe, chaos, torment, and sorrow; unlike any event ever seen on earth.
In verses 12 – 22 we are instructed in our daily lives, how we ought to live. It involves respect to our spiritual leaders, warning those who reject authority, beiing thankful, rejoicing, praying, our responses to the preaching [prophecy] of the Word and other such things.
Verses 23 – 38 is the conclusion of the letter. There is much to this conclusion – our sanctification; the faithfulness of God (v. 24; see also Philippians 1:6), a request for prayer, and the way we are to greet one another.

“But of the times and the seasons, brethren, ye have no need that I write unto you. For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.” 1 Thessalonians 5:1-2 (KJV)

Paul had evidently spoken to the Church concerning times and seasons before he was ran out of town, but here is a friendly reminder.
Why should the teaching of the rapture of the Church and “The day of the Lord” be preached and taught? 1.) For comfort and encouragement to Believers; 2.) For the purity of the Believer (2 Peter 3:14); 3.) For a zeal in the hearts of Believers for those who are lost (2 Peter 3:9, 10); 2 Corinthians 5:11); 4.) “For the testimony of Jesus is the spirit of prophecy” (Revelation 19:10).
Jesus will come like a thief when He comes in the clouds. Only those who know HIm will rise to meet Him in the air. When people suddenly realize a co-worker, a wife, or husband, son or daughter, a friend, the driver of an automobile, the pilot of an airplane (Private or Commercial), the pastor, the deacon, or a Sunday School/Bible Study teacher is missing there will be such chaos as the world has never seen. There are people unaware. These people who are still in darkness.

“For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape. But ye, brethren, are not in darkness, that that day should overtake you as a thief.” vv. 3-4

The world is longing for peace. We are hungry for it. We can almost taste it. When it appears there is peace; when it appears that economic peace and recovery is here, that there is peace from war and strife; that is when the people will be at ease. Nothing destructive will happen, people believe all is well. Who would dare upset our progress? Jesus will come, and the unprepared “Shall not escape”.
This day will not came “As a thief” for the prepared (See Matthew 25:1-13). This word “Darkness” is used in reference to those who are outside of Jesus. Therefore, if one is in the light he is not in darkness.

“Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness. Therefore let us not sleep, as do others; but let us watch and be sober. For they that sleep sleep in the night; and they that be drunken are drunken in the night. But let us, who are of the day, be sober, putting on the breastplate of faith and love; and for an helmet, the hope of salvation.” vv. 5-8

Sleeping is one of the times in our lives when we are unaware. When we are asleep we could almost care less for what goes on around us. It is a dangerous time.
This sleep is of the spiritual sort. Unaware of the darkness. Unaware of the peril that is in the path ahead. It means satisfied with the way things are – COMPLACENCY. Indifferent, uncaring, about what is ahead – you know, bur you are unwilling to act upon it – APATHY.
“Let us not sleep”, but let us be aware, able to control ourselves, watching, waiting for the Lord’s appearing, which is the “Blessed hope” (Titus 2:13). Those who are watching are those “Who love His appearing” (2 Timothy 4:8). Jesus commands us to watch (Matthew 24:42-43; Luke 12:35-40). The person (The Believer) who is watching is an alert Believer. We are to be “Watchmen” sounding an alarm to the populace (See Ezekiel 33:1-6). The Watchmen must remain awake.
There are all kinds of evil wickedness going on in the darkness. People doing their evil, hate for light to expose it (John 3:19). The ones who participate in the darkness are not people of light. They too need the light.
The”Breastplate of faith” is to turn the fiery darts of Satan, which is constantly hurled at the children of light. The “Helmet of Salvation” is on our head where we have most of our sense – sight, smell, sound, and taste; and the head is also the control centel for the body. We reason with our head. Is it any wonder we must have the Helmet of Salvation”.

“For God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ, who died for us, that, whether we wake or sleep, we should live together with Him. Wherefore comfort yourselves together, and edify one another, even as also ye do.” vv. 9-11

It is pretty evident by verse nine that God has not intended for His Church to go through the “Time of Jacob’s trouble” which we call “The great tribulation period”. It does not stand on the one verse alone though (See Revelation 3:10-11; 2 Thessalonians 2:7). It stands on the death, burial and resurrection of Jesus Christ.
The comfort of these words are not empty. Where would the comfort be if we had to endure “Great tribulation”? We endure tribulation already, but nothing the like of which awaits the “Day of the Lord”, when all living unbelievers will be tried and “They shall not escape”; except through faith in the Lord Jesus Christ, and very likeable persecution death.

“And we beseech you, brethren, to know them which labour among you, and are over you in the Lord, and admonish you; and to esteem them very highly in love for their work’s sake. And be at peace among yourselves. Now we exhort you, brethren, warn them that are unruly, comfort the feebleminded, support the weak, be patient toward all men. See that none render evil for evil unto any man; but ever follow that which is good, both among yourselves, and to all men. Rejoice evermore. Pray without ceasing. In every thing give thanks: for this is the will of God in Christ Jesus concerning you. Quench not the Spirit. Despise not prophesyings. Prove all things; hold fast that which is good. Abstain from all appearance of evil.” vv. 12-22

Here is listed some things which seem to indicate those who are awake, aware, and ready for the Lord’s return.
vv. 12-13 – Having respect for your pastor, deacon(s), teachers, the ones who are responsible for your spiritual well being. Hold them up in prayer for boldness, love, and encouragement.
This is certainly not an excuse for overlooking a false preacher or teacher, but one who teaches and believes the Bible is the inerrant, infallible, Holy Spirit inspired Word of God.
PEACE = Not constantly squabbling, quarelling, but working in unity for the same cause and purpose. If the Church cannot be at peace with one another there is little hope for the world to be at peace.
v. 14 – The word “Unruly” means insubordinate (in religious matters) which is an unwillingness to submit to authority. We are told to warn such, and not to be in such a case ourselves.
Encouragement is always needed. When others encourage us we are motivated to serve the Lord in a greater capacity. We can minister to others with encouragement.
v. 15 – Always pursue the good. Do good to others even when they treat you wickedly.
v. 16 – Rejoicing is a sign of no fear, a sign of peace and contentment. When we rejoice in our Lord there is also a witness to those around us.
v. 17 – Pray for perseverance. Keep on bringing your requests to the Lord until He answers – He will either give what you ask, or He willl say “No!” or He might say “Wait!”
v. 18 – When others around are complaining, whether about their work, home, family, sickness, or Church, we are to be thankful “In everything” knowing that God is in control of the circumstances and He is using themto make us stronger and better Christians.
v. 19 – The Holy Spirit is likened unto fire. To quench a fire we often dump water on it – we put the fire out. To “Quench the Spirit” is to hear Him speak to us, but determine we will not heed His leading, and do our own rebellous act. This is sin, and one that is very often committed by all of us. We do not have time, or not right now, or somebody else can do it are words often expressed that quenches the fire of the Spirit.
v. 20 – Prophecy is the “Foretelling” of the future and/or the “Forthtelling” of the Word of God. All the prophets of the Bible “Foretold” the future – but even more important they were “Forthtellers” of God’s Word. Many, many times when God’s prophet told of some future event it was confirmed as the Word of the Lord by a present or imminent sign. Today the prophet of God only foretells by the written Word of God, and it is confirmed in that same word. He also forthtells by that same word.
The word “Despised” means contemptible, least esteemed – to have no delight in. It means you may like music in the worship, but you cannot stand the preaching of the word. It makes you uncomfortable, you want to get out as quickly as possible. Ask yourself “Why?” You are uncomfortable in the presence of God, and His holy Word. That is why. Proverbs 13:13 states, “He who despises the Word will be destroyed.”
v. 21 – Goes along with verse twenty. When a man stands to deliver God’s message there is to be a test. Does it come from God, or does it contradict His Word? If it goes against the Bible; it is not a message from God.
v. 22 – Staying away from every form of evil is the Christians calling, ife we are prepared for His coming. If it shows up, and you are tempted by it flee from it; run with all the strength you have – run from it.

“And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ. Faithful is He that calleth you, who also will do it.” vv. 23-24

God Himself is the One who sets us apart from all others, and He preserves us blameless for the coming of Jesus His Son.
God is faithful. He started the work, and He has never left His work undone. The work He has began in you He will complete (Philippians 1:6).

“Brethren, pray for us. Greet all the brethren with an holy kiss. I charge you by the Lord that this epistle be read unto all the holy brethren. The grace of our Lord Jesus Christ be with you. Amen.” vv. 25-28

A request for prayer, greeting and a charge or challenge to read this epistle to all Christians is given by Paul in closing.
His request for prayer was not just empty words. Paul knew the importance of prayer.
Never short on grace he always left it with others. So ought we as well.
