The reason people have trouble with the temple theme is because they are already missing the mission. IN the 3 chapters on being ministers of the new covenant (a temple term) and doing the 'ministry that brings righteousness' (a temple term), the temple Paul is speaking of is all those who minister for this covenant (2 Cor 3-6). The 'shekinah' (a temple term) shines all the time from this temple because Christ is the glory. No one ever need veil their faces in dismay at a fading glory again! This temple does not have human-operated offices sending out official letters of authority with its envoys about the 'tablets written in stone' but people on whom the Spirit of God has written the law of love. Jer 32 and Ezek 37 are fulfilled; God does 'walk among' his people now, in this temple. Its mission is to help all the nations see and believe on him; it is necessarily transcultural and mobile.
--Inter
Now, brethren, concerning the coming of our Lord Jesus Christ and our gathering together to Him, we ask you, 2 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 had come. 3 Let no one deceive you by any means; for that Day will not come unless the falling away comes first, and the man of sin is revealed, the son of perdition, 4 who opposes and exalts himself above all that is called God or that is worshiped,
so that he sits as God in the temple of God, showing himself that he is God.
2 Thessalonians 2:1-4
The problem with trying to explain away what Paul clearly taught us is -
The man of sin is a man, not a spirit. for it is written -
And now you know what is restraining,
that he may be revealed in his own time.
The man of sin will be revealed, in his own time for the purpose of deceiving those who do not have the love of the truth and had pleasure in unrighteousness. He will deceive by working miracles after the coming of Satan.
This man will been seen and known by all he deceives.
He will go to the temple and proclaim himself as God.
He will be destroyed by Jesus Christ Himself.
He is not invisible.
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. 2 Thessalonians 2:8-12
