2 Thessalonians 2:9-12

Verse 9

Whose coming is after the working of Satan - The operation of God's Spirit sends his messengers; the operation of Satan's spirit sends his emissaries. The one comes κατ' ενεργειαν του Θεου, after or according to the energy or inward powerful working of God; the other comes κατ' ενεργειαν του Σατανα, according to the energy or inward working of Satan.

With all power - Πασῃ δυναμει· All kinds of miracles, like the Egyptian magicians; and signs and lying wonders: the word lying may be applied to the whole of these; they were lying miracles, lying signs, and lying wonders; only appearances of what was real, and done to give credit to his presumption and imposture. Whereas God sent his messengers with real miracles, real signs, and real wonders; such Satan cannot produce.
Verse 10

And with all deceivableness of unrighteousness - With every art that cunning can invent and unrighteousness suggest, in order to delude and deceive.

In them that perish - Εν τοις απολλυμενοις· Among them that are destroyed; and they are destroyed and perish because they would not receive the love of the truth, that they might be saved. So they perish because they obstinately refuse to be saved, and receive a lie in preference to the truth. This has been true of all the Jews from the days of the apostle until now.
Verse 11

God shall send them strong delusion - For this very cause, that they would not receive the love of the truth, but had pleasure in unrighteousness, therefore God permits strong delusion to occupy their minds; so that they believe a lie rather than the truth, prefer false apostles and their erroneous doctrines to the pure truths of the Gospel, brought to them by the well-accredited messengers of God; being ever ready to receive any false Messiah, while they systematically and virulently reject the true one.
Verse 12

That they all might be damned - Ἱνα κριθωσι· So that they may all be condemned who believed not the truth when it was proclaimed to them; but took pleasure in unrighteousness, preferring that to the way of holiness. Their condemnation was the effect of their refusal to believe the truth; and they refused to believe it because they loved their sins. For a farther and more pointed illustration of the preceding verses, see the conclusion of this chapter (note).
