Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God. Remember ye not, that, when I was yet with you, I told you these things? And now ye know what withholdeth that he might be revealed in his time.

For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way. And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming: Even him, whose coming is after the working of Satan with all power and signs and lying wonders, And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.

And for this cause God shall send them strong delusion, that they should believe a lie: That they all might be damned who believed not the truth, but had pleasure in unrighteousness. But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth: Whereunto he called you by our gospel, to the obtaining of the glory of our Lord Jesus Christ.

Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle. Now our Lord Jesus Christ himself, and God, even our Father, which hath loved us, and hath given us everlasting consolation and good hope through grace, Comfort your hearts, and stablish you in every good word and work. (2 Thessalonians 2:3-17 kjv)

The Second Epistle of Paul to the THESSALONIANS This second letter of Paul to the Thessalonians was written about A.D. 51 -52. and was sent from Corinth soon after his first letter. Some members of the congregation in Thessalonians did not have a clear understanding of Paul's teaching concerning the "Day of the Lord' a his first epistle to them (1 Thess. 5:1 -11). There was also a misunderstanding among some of the people regarding the imminent return of the Lord Jesus.   They apparently had misinterpreted the meaning of the phrase "as a thief in the night" (1 Thess. 5:2) and confused the concepts of the suddenness of the Lord's coming with its immediacy. They thought that since Christ would be coming soon, there was no point in continuing to work. When the people encountered increased persecution, they felt that the 'Day of the Lord' had already come and they had somehow missed Christ's return. Paul corrects them in this second epistle by explaining that certain events must take place before Christ will return. For example, he states that there will be a world-wide rebellion against God, led by one who will represent the epitome of lawlessness and anarchy (2 Thess. 2:3 -9). Moreover, Paul tells the believers in Thessalonica not to live at the expense of others, but to the Lord's work (2 Thess. 3:10 -12). In summary, the Thessalonians were apprehensive about the persistent persecution that they were enduring (2 Thess. 1:4, 5). Paul wrote this letter to comfort and exhort these believers to continue serving the Lord in spite of the hardships.
