William Burkitt on 2 Thessalonians 2:9

An account is here given how Antichrist doth acquire and keep up his power in the world: the first and great instrument is Satan; after the working of Satan, is as much as, by the working of Satan, denoting not only his pattern but his influence. The devil has a great hand over wicked men in the world, his way of dealing with them is most efficacious and powerful; he is certainly the first founder and supporter of the Antichristian state.

Observe, 2. The subordinate instrumental means by which Antichrist gained his power in the world; namely, by pretended miracles: With all power, and signs, and lying wonders. Miracles are called powers, because the effects of extraordinary powers; signs, from their use, because they sealed the doctrine to which they are applied; wonders, because they breed astonishment in the minds of beholders. Now Antichrist pretends to all these, but his are lying powers, lying signs, and lying wonders; because the greatest of his pretended miracles are fables, forgeries, impostures, diabolical delusions.

Learn hence, That Antichrist doth uphold and support his kingdom by a false show of signs, wonders, and mighty deeds; they are mira, but not miracula; what he cannot prove by the oracles of God, he endeavours to prove by the miracles of Satan.
