2 THESSALONIANS 2:1-12 NEB.
"And now, brothers, about the coming of our Lord Jesus Christ and his gathering of us to himself: I beg you, do not suddenly lose your heads or alarm yourselves, whether at some oracular utterance, or pronouncement, or some letter purporting to come from us, alleging that the Day of the Lord is already here.♦ Let no one deceive you in any way whatever. That day cannot come before the final rebellion against God, when wickedness will be revealed in human form, the man doomed to perdition. He is the Enemy. He rises in his pride against every god, so called, every object of men's worship, and even takes his seat in the temple of God claiming to be a god himself.
You cannot but remember that I told you this while I was still with you; you must now be aware of the restraining hand which ensures that he shall be revealed only at the proper time. For already the secret power of wickedness is at work, secret only for the present until the Restrainer* disappears from the scene. And then he will be revealed, that wicked man whom the Lord Jesus will destroy with the breath of his mouth, and annihilate by the radiance of his coming. But the coming of that wicked man is the work of satan. It will be attended by all the powerful signs and miracles of the Lie, and all the deception that sinfulness can impose on those doomed to destruction. Destroyed they shall be, because they did not open their minds to love of the truth, so as to find salvation. Therefore God puts them under a delusion, which works upon them to believe the lie, so that they may all be brought to Judgement, all who do not believe the truth but make sinfulness their deliberate choice." (2 Thess 2:1-12 NEB).
The Opened "Little Scroll" is the fulfilment of the prophecy of Revelation 10:8-11. It contains denunciations against "every lofty thing raised up against the knowledge of God", against the "powerful signs and miracles of the Lie" and therefore against the "final rebellion against God". (2 Cor 10:5). It reveals that this wickedness "in human form" is a composite "man of lawlessness" made up of many members, who misused the Word of God to give power to their self-promoting apostate teachings, and to usurp the authority of Spirit anointed servants of the temple of God. (2 Thess 2:3,4). By refusing to open their minds to love the truth issued by God through His faithful anointed servants, and then by spiritually "trampling", ostracizing, and ousting them, these apostate men of lawlessness did thereby declare themselves the authority over every object of men's worship, even over Almighty God Himself !
The radiance of the coming of our Lord will illuminate the "Little Scroll". It is the basis for Judgement, by which he will destroy the composite "man of lawlessness" by the "Spirit of his mouth". (2 Thess 2:8).
