even he whose coming is according to the working of Satan with all power and signs and lying wonders,
"Lying wonders" refer to the fraudulent "power" and "signs" being performed for the purpose of deceiving others. These types of powers and signs were more of magical qualities or strong delusions than true miracles, simply making things appear different from the way they actually were. Many people were deceived by believing a lie, thinking that what they witnessed was a true miracle. Paul says, "For this cause God shall send them strong delusion, that they should believe a lie" (verse 11).
