The Coming “Day of the Lord”
Part 1—The Fake Epistle and the Troubling Message
“Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him, that ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand.”
(2 Thessalonians 2:1-2)
In the three short weeks when the Apostle Paul was in the city of Thessalonica (in A.D. 53), he taught the brand-new church of Thessalonica the doctrine of the coming of the Lord; and the people received this doctrine (as well as all the other doctrines that Paul taught them) with great enthusiasm (Acts 17:1-9). However, after Paul left them under the pastoral care of one of his missionary co-workers, and moved on to the city of Berea, the believers in Thessalonica still some questions about the coming of the Lord. Particularly, they weren’t sure of what the status of their already-deceased brethren in Christ would be on the resurrection day. Thus, Paul wrote his first letter to the Thessalonians to clear up their questions. In that epistle, Paul gave this beautiful description of the “catching up” (what we often call “the Rapture”) of believers, which will occur at the end of this church age:
“But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope.
For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him.
For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep.
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:
Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
Wherefore comfort one another with these words.”
(1 Thessalonians 4:13-18)
Paul’s words were clear enough: one day, Christ will suddenly appear in the clouds of Heaven; and all who were “in Christ” (saved) during this present church age will be resurrected, and caught up in the air to meet the Lord. Those who are “asleep in Jesus” (those who had died, and whose bodies are “sleeping” in their graves) will be resurrected to life, re-united with their spirits (which had been with the Lord in Heaven), and will be caught up in the air, to meet the Lord; and immediately afterward, those who are still living, and who are “in Christ,” will also be caught up in the air, to meet the Lord. “In a moment, in the twinkling of an eye,” every true believer in Jesus Christ (both those who were dead, and those who are still living) will receive glorified, immortal, incorruptible bodies, as Paul teaches in 1 Corinthians 15:51-58. Paul had already taught all these things to the Thessalonian believers; and in his first epistle to them, he confirmed them in these truths.
However, the people still had questions. In his second letter to the Thessalonians, Paul once again had to address a doctrinal issue in regard to the coming of the Lord. Apparently, someone claiming to be the Apostle Paul had written a forged letter to the church of Thessalonica (verse 2); and in this letter, the author claimed that the “day of Christ” had already arrived. In other words, this person was saying that they had now entered into the Tribulation period.
Whoever wrote this letter was flatly denying what Paul had taught the Thessalonians. Paul had taught them “the pre-Tribulation Rapture” (the doctrine that the Rapture, or “catching up” of the saints, will happen just before the Tribulation). In stark contrast, this forger had taught the Thessalonians that that the Rapture of New Testament saints will happen just after the Tribulation. Needless to say, the Thessalonians were greatly “shaken in mind” and “troubled” because of this forger’s words! Paul had clearly taught them that they would be “caught up” in the clouds just before the start of the Day of the Lord, and that they were “not appointed unto wrath” (1 Thessalonians 4:16-5:3, 9-10); but now, someone else was telling them that New Testament believers must go through the terrible “day of the Lord.”
Now, it is important to remember that Paul used the term “day of Christ” instead of “Day of the LORD.” There is a slight difference of emphasis between the two. These two terms refer to two different aspects of Christ’s coming. The “day of the LORD” (“yom Jehovah,” as it is called in Hebrew) is a term that is used many times in the Old Testament; and it is translated into the New Testament as “the day of the Lord” (using the Greek word Kuriou, for “Lord”). The “day of the LORD” is not a 24-hour day, but rather a future period of 1,007 years. It includes the seven-year Tribulation period, the return of Christ to earth at the end of the Tribulation, and the 1,000-year Kingdom that follows (Zechariah 14:1-21; Daniel 9:26-27; Revelation 20:1-6). The Day of the LORD might be described as “a period of history when the LORD completes His work of judgment on the wicked, and the deliverance of His people.”
What, then, is the “day of Christ”? The “day of Christ” is a New Testament term which refers to the same seven-year period of time as the “day of the LORD.” However, the difference is that “the day of Christ” refers to what will be happening in Heaven, while the “day of the Lord” is in progress down on earth. The “Day of Christ” includes the Rapture of New Testament saints, followed by the Judgment Seat of Christ for New Testament believers in Heaven (1 Corinthians 3:11-15; 2 Corinthians 5:10; Revelation 4:1-11). While New Testament age Christians are in Heaven being judged and rewarded in the “day of Christ,” the unsaved will be experiencing the horrors of “the day of the LORD” down on earth.
With this in mind, you’ll notice that Paul appealed to the Thessalonians “by the coming of our Lord Jesus Christ, and by our gathering together unto him.” First, Paul appealed to them “by the coming of our Lord Jesus Christ.” The word “coming” is translated from the Greek word parousia, which simply means “coming,” or “presence.” This word parousia can refer either to the actual coming of Christ to earth at the end of the Tribulation (such as in 2 Thessalonians 2:8), or to the Rapture of the New Testament saints in the clouds just before the Tribulation (such as in 1 Thessalonians 3:13; 4:15). In this case (here in 2 Thessalonians 2:1), the word parousia apparently refers to the return of Christ to earth at the end of the Tribulation, because Paul contrasts it to “our gathering together unto him.” Clearly, the phrase “our gathering together unto him” refers to the Rapture, whereas the “coming of our Lord Jesus Christ” refers to Christ’s actual return to earth. Paul is saying, “I am urging you by the Second Coming of Christ (which will happen at the end of the Tribulation), and by the Rapture (which will happen just before the Tribulation).” He is drawing a distinction between these two phases of Christ’s coming.
Now, it is plain to see what effect the teaching of the forger had had on the Thessalonians. The biblical teaching of the Rapture (particularly, the pre-Tribulation Rapture) causes rest of mind (2 Thessalonians 1:7); yet, the Thessalonians were “troubled” in mind. Why? Because if they were now living in the “day of the Lord” (the seven-year Tribulation period), and had not been caught up in the Rapture, then they would soon be seeing the horrific judgments of the Tribulation!
All doctrine (including end-times doctrine) does matter! This is why it is vitally important that we “rightly divide the word of truth” (2 Timothy 2:16). If you know Christ as your Saviour, may your heart be comforted today as you think on the wonderful promise of the coming of our Lord in the clouds!
If you have never repented of your sin and believed on the Lord Jesus Christ, don’t put off the matter of salvation. Christ might catch up His people this very day, and you would be left behind to go through the wrath of the Tribulation. As we will see in later posts, many people will believe on Christ and be saved during the Tribulation; however, the cost for believing on Jesus during that horrible seven-year period will be ex*****on (Revelation 13:1-18). Furthermore, there will be great demonic delusion during the Tribulation, which will prevent the overwhelming majority of people from believing on Christ (2 Thessalonians 2:9-12). If you are consciously rejecting Christ now, it is unlikely that you will receive him during the Tribulation, when Satan will be deluding the minds of men with unprecedented power. Don’t keep playing around in sin, and gambling with your soul! Believe on the Lord Jesus Christ, before the trumpet of the Lord sounds!
