1 Now concerning the times and the seasons, brothers, you have no need to have anything written to you. 2 For you yourselves are fully aware that the day of the Lord will come like a thief in the night. 3 While people are saying, “There is peace and security,” then sudden destruction will come upon them as labor pains come upon a pregnant woman, and they will not escape. 4 But you are not in darkness, brothers, for that day to surprise you like a thief. 5 For you are all children of light, children of the day. We are not of the night or of the darkness. 6 So then let us not sleep, as others do, but let us keep awake and be sober. 7 For those who sleep, sleep at night, and those who get drunk, are drunk at night. 8 But since we belong to the day, let us be sober, having put on the breastplate of faith and love, and for a helmet the hope of salvation. 9 For God has not destined us for wrath, but to obtain salvation through our Lord Jesus Christ, 10 who died for us so that whether we are awake or asleep we might live with him. 11 Therefore encourage one another and build one another up, just as you are doing.– 1 Thessalonians 5:1-11 ESV
Paul has just addressed the Thessalonians’ concern about the spiritual state of their deceased friends and relatives. The loss of their loved ones had created a sense of unease and confusion among the believers because they had been anticipating the return of Jesus. One of the things Paul and the other apostles had to constantly deal with was the immature and incomplete nature of the new converts to whom they ministered. The global church was growing rapidly, and the new followers of Christ lacked much in the way of doctrinal instruction. Most had a rudimentary knowledge of Jesus Christ and His offer of salvation. They most likely understood that Jesus had resurrected and would one day return. But it appears that, beyond that, their understanding was incomplete.
That is why Jesus had instructed the apostles, “Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you” (Matthew 28:19-20 NLT). It was not going to be enough just to share the gospel message. Any new followers of Christ were going to need to hear His words, taught and expounded upon, in order to grow in their faith. And one of the things Jesus taught to His disciples was the coming day of the Lord. He wanted His followers to understand that God had a grand plan in place, that included not only His Son’s death, burial, resurrection, and ascension, but His future return. Paul has just reminded his readers about the Rapture when Jesus will return for His bride, the church. Now, he shifts his focus to another end-times event, the day of the Lord.
This designation, “the day of the Lord,” was used by Jesus, Paul and Peter to refer to a future period of time when God will intervene on the earth in spectacular fashion. He will bring judgment upon the earth and its inhabitants and usher in the final phase of redemptive history. And, while every believer needs to be aware of the reality of these coming events, Jesus made it clear that no one can know their exact timing.
“It is not for you to know times or seasons that the Father has fixed by his own authority.” – Acts 1:7 ESV
“But concerning that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father only.” – Matthew 24:36 ESV
Yet, it is human nature to want to know how and when these end-times events are going to happen. And while Jesus provided His disciples with significant details regarding the events surrounding the day of the Lord, He did not tell them when it would happen – only that it would. And Paul had evidently taught the Thessalonians about these coming end-times events, referring to them as “the times and the seasons.” His use of the Greek words chronos and kairos seems to be in order to stress the “the times” – a reference to the period of waiting or delay that precedes the day of the Lord – and “the seasons” – referring to the actual events themselves. In other words, Paul had taught them about the coming day of the Lord, a time when God will bring judgment upon the earth. But he had also taught them about the days leading up to that time – that period in which all believers live until God’s ordained outcome takes place.
Paul had already taught the Thessalonians that “the day of the Lord will come like a thief in the night” (1 Thessalonians 5:2 ESV). And when Paul used this phrase, he was referring not only to the second coming of Christ, but also the events leading up to His return. For Paul, the day of the Lord included the seven years of Tribulation, when God will pour out His judgments upon mankind, as well as Christ’s second coming that will occur at the end of the seven years and usher in the Millennial Kingdom. These future events are all included in the day of the Lord, and their arrival will come unexpectedly. A thief comes when the home’s occupants least expect him. They are unaware of his plans and unprepared for his arrival. In their minds, “Everything is peaceful and secure” (1 Thessalonians 5:3 NLT). Paul uses the metaphor of a pregnant woman who, after nine months of waiting, has grown used to being pregnant. She has grown accustomed to her condition. And then, suddenly, the contractions begin. Even though she has had nine months to prepare herself for this moment, she is still caught off guard by the severity and speed of the labor pains.
But Paul reminds the Thessalonians that they have no reason to be caught off guard by the news of these future events. They had been warned. They had been fully informed that God has a future plan in store for mankind. And it will all begin with the return of the Lord for the church. The Rapture is what will introduce the rest of the end-times events. With the removal of all believers from the earth, the stage will be set for God to prepare all those who remain for His righteous judgment. The absence of any Christians on the earth will leave a tremendous spiritual void in which unrighteousness will be free to spread unabated. And in this moral and spiritual vacuum, the Antichrist will quickly rise to power, and an apostate church will rise to prominence. The following seven years referred to as the Tribulation, will be marked by unprecedented unrighteousness and wickedness. Jesus described it in foreboding terms: “For then there will be great tribulation, such as has not been from the beginning of the world until now, no, and never will be” (Matthew 24:21 ESV).
The Thessalonians had been informed about these coming days, but it appears that they were still confused. In fact, in his second letter to them, Paul goes into further detail about the day of the Lord, attempting to allay any further fears or misunderstanding they had.
Now concerning the coming of our Lord Jesus Christ and our being gathered together to him, we ask you, brothers, not to be quickly shaken in mind or alarmed, either by a spirit or a spoken word, or a letter seeming to be from us, to the effect that the day of the Lord has come. – 2 Thessalonians 2:1-2 ESV
The bottom line for Paul was preparedness. He wanted the believers in Thessalonica to live in a state of constant readiness, fully ready for the Lord to return for them at any time. He told them, “let us not sleep, as others do, but let us keep awake and be sober” (1 Thessalonians 5:6 ESV). There is no place for complacency in the life of a believer. We know the Lord is coming back, so we should live like it. We don’t live in darkness or ignorance, like the rest of the world. We are children of the light and have had our minds illuminated by the truth of God’s Word.
There was no reason for the Thessalonians to fear. They were in Christ and were being preserved by Him for their future salvation. That is why Paul tells them to rely upon “breastplate of faith and love.” They were shielded from the judgment to come by their faith in Christ and God’s love for them. Paul had promised the Roman believers that “not even the powers of hell can separate us from God’s love” (Romans 8:38 NLT). And they had access to “the helmet of salvation” to protect their thoughts and minds. They were guaranteed a place in God’s Kingdom, and Paul provided them with the reassuring words: “God has not destined us for wrath, but to obtain salvation through our Lord Jesus Christ” (1 Thessalonians 5:9 ESV). They did not need to fear the coming judgment of God because His Son was coming back for them.
But they did need to be ready. So, he told them “to encourage one another and build one another up.” They were living in “the times” – the period of time before the Lord returns and the day of the Lord commenced. They had no way of knowing when Jesus was coming back, but they needed to live in eager anticipation of that day and prepared for it to happen at any moment. And Paul emphasized this same spirit of readiness when writing to the believers in Ephesus, urging them to dress for the spiritual war in which they were engaged.
Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand firm. Stand therefore, having fastened on the belt of truth, and having put on the breastplate of righteousness, and, as shoes for your feet, having put on the readiness given by the gospel of peace. In all circumstances take up the shield of faith, with which you can extinguish all the flaming darts of the evil one; and take the helmet of salvation, and the sword of the Spirit, which is the word of God… – Ephesians 6:13-17 ESV
Jesus is coming back one day and the day of the Lord will take place. But until that day, we are to live in a constant state of preparedness, realizing that, until He comes, we must fight the good fight to the end.
