not to be soon shaken in mind or troubled, either by spirit or by word or by letter as if from us, as though the day of Christ (2nd Coming) had come.
Let no one deceive you by any means: for that Day (2nd Coming) will not come unless the falling away comes first (the departure from the true word of God in a professing church),and the man of sin is revealed, the son of perdition, (Antichrist)
who opposes and exalts himself above all that is called God or that is worshiped(the beast will tolerate the worship of no one or nothing but himself: Rev. 13: 5-8), so that he sits as God in the temple of God, showing himself that he is God.
Do you not remember that when I was still with you I told you these things? (this teaching was nothing new to the Thessalonians; Paul had taught them about the day of the Lord when he was with them in Thessalonica. He called on them to recall those lessons.)
And now you know what is restraining (HS in the church), that he may be revealed in his own time.
For the mystery of lawlessness (Antichrist) is already at work; only He (HS) who now restrains will do so until He (HS) is taken out of the way. (Genesis 6:3 And the Lord said, My Spirit (HS) shall not strive with man forever, for he is indeed flesh; yet this days shall be one hundred and twenty years.( (The removal of the restrainer at the Rapture precede the day of the Lord. The Thessalonians were not in the Great Tribulation because the Rapture had not yet occurred.)
And then the lawless one(Daniel 9:26;27 And after the sixty-two weeks Messiah shall be cut off,but not for Himself; and the people of the prince who is to come (lawless one) shall destroy the city and the sanctuary. The end of it shall be with a flood. And till the end of the war desolations are determined. Then he shall confirm a covenant with many for one week; but in the middle of the week He shall bring an end to sacrifice and offering. And on the wing of abominations shall be one who makes desolate. Even until the consummation, which is determined. Is poured out on the desolate.) will be revealed, whom the Lord will consume with the breath of His mouth and destroy with the brightness of His coming. (Spans the seven-year career of the Antichrist from the time he makes a covenant with Israel soon after the Rapture, till his overthrow by Christ at His second coming at the end of the Tribulation)
The coming of the lawless one is according to the working of Satan (indwell by Satan~Rev. 13:2~the dragon gave him his power, his throne, and great authority), with all power, signs,and lying wonders.(the lawless leader will perform such powerful miracles that it will be evident to all that he has supernatural power,and people will stand in awe of him. Rev. 13:2b-4 and 17:8)
and with all unrighteous deception among those who perish, because they did not receive the love of the truth, that they might be saved.(their own choice brings about their condemnation)
And for this reason God will send them strong delusion, that they should believe the lie,(His miracles are not the only thing that will deceive people into thinking he has divine power. Everything he does will mislead people, especially those whose minds are blinded to the truth of who he is and what he is doing because they do not believe God's Word)(they choose to believe the lie and God sends them the delusion that is inherent in their choice. This powerful judgment from God is justified by the unbelievers' decision to refuse the truth. The lie is the claim that the man of lawlessness is God.)
that they all may be condemned who did not believe the truth,but had pleasure in unrighteousness.
