2 Thessalonians 2:3-4. 8-12

No one is to deceive you in any way! For it will not come unless the apostasy comes first, and the man of lawlessness is revealed, the son of destruction, who opposes and exalts himself above every so-called god or object of worship, so that he takes his seat in the temple of God, displaying himself as being God.

Then that lawless one will be revealed, whom the Lord will eliminate with the breath of His mouth and bring to an end by the appearance of His coming; that is, the one whose coming is in accord with the activity of Satan, with all power and false signs and wonders, and with all the deception of wickedness for those who perish, because they did not accept the love of the truth so as to be saved. For this reason God will send upon them a deluding influence so that they will believe what is false, in order that they all may be judged who did not believe the truth, but took pleasure in wickedness. (NASB)
