2 Thessalonians 2:4

2:4 He opposes and exalts himself above every so-called god or object of worship, and as a result he takes his seat in God’s temple, displaying himself as God.

2 Thessalonians 2:9-12

2:9 The arrival of the lawless one will be by Satan’s working with all kinds of miracles and signs and false wonders, 2:10 and with every kind of evil deception directed against those who are perishing, because they found no place in their hearts for the truth so as to be saved. 2:11 Consequently God sends on them a deluding influence so that they will believe what is false. 2:12 And so all of them who have not believed the truth but have delighted in evil will be condemned.
