2 Thessalonians 2:9

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.
