2 Thessalonians 2:3-4, 9-12

Don’t let anyone deceive you in any way. Before that day comes the rebellion must occur and the “outlaw” —the destructive son—will be revealed in his true light. He is the opposing counterpart who exalts himself over everything that is called “God” or is worshiped and who sits enthroned in God’s temple and makes himself out to be a god.

The presence of the “outlaw” is apparent by the activity of Satan, who uses all kinds of counterfeit miracles, signs, spurious wonders, and every form of evil deception in order to deceive those who are perishing because they rejected the love of the truth that would lead them to being saved. Because of this, God sends them a powerful delusion that leads them to believe what is false. So then all who found their pleasure in unrighteousness and did not believe the truth will be judged.
