If every man is the 'man of sin' then why did Paul write like he did?
Cause every man before they are saved is a slave of sin and following Satan as sons of disobedience, that was well taught to the early church.
Ephesians 2
And you
He made alive, who were dead in trespasses and sins, 2 in which you once walked according to the [
a]course of this world, according to the prince of the power of the air, the spirit who now works in the sons of disobedience, 3 among whom also we all once conducted ourselves in the lusts of our flesh, fulfilling the desires of the flesh and of the mind, and were by nature children of wrath, just as the others.
The difference for that coming man of sin Paul writes like this,
2 Thessalonians 2
6 And now you know what is restraining, that he may be revealed in his own time. 7 For the [
d]mystery of lawlessness is already at work; only [
e]He who now restrains
will do so until He is taken out of the way. 8 And then the lawless one will be revealed, whom the Lord will consume with the breath of His mouth and destroy with the brightness of His coming. 9
The coming of the lawless one is according to the working of Satan, with all power, signs, and lying wonders, 10 and with all unrighteous deception among those who perish, because they did not receive the love of the truth, that they might be saved. 11 And for this reason God will send them strong delusion, that they should believe the lie, 12 that they all may be condemned who did not believe the truth but had pleasure in unrighteousness.
Paul describes the lawless one as fully empowered by Satanic powers, satanic signs, lying wonders who deceives the entire unbelieving world.
These are not the general attributes of everyday unbelieving sinners....
Meaning it points to someone special and different.
It also agrees with what Christ taught about who shows up right before He returns a second time bodily in a glorious appearing....
Paul and Jesus are describing the same things and event here and the same second coming of Christ.
Mark 13
19 For
in those days there will be tribulation, such as has not been since the beginning of the creation which God created until this time, nor ever shall be. 20 And unless the Lord had shortened those days, no flesh would be saved; but for the elect’s sake, whom He chose, He shortened the days.
21 “Then if anyone says to you, ‘Look, here is the Christ!’ or, ‘Look, He is there!’ do not believe it.
22 For false christs and false prophets will rise and show signs and wonders to deceive, if possible, even the [g]elect.
23 But take heed; see, I have told you all things beforehand.
The Coming of the Son of Man
24 “But in those days, after that tribulation, the sun will be darkened, and the moon will not give its light; 25 the stars of heaven will fall, and the powers in the heavens will be shaken. 26 Then they will see the Son of Man coming in the clouds with great power and glory.
27
And then He will send His angels, and gather together His [h]elect from the four winds, from the farthest part of earth to the farthest part of heaven.
