As to the coming of our Lord Jesus Christ and our being gathered together to him, we beg you, brothers and sisters, not to be quickly shaken in mind or alarmed, either by spirit or by word or by letter, as though from us, to the effect that the day of the Lord is already here.
Let no one deceive you in any way; for that day will not come unless the rebellion comes first and the lawless one is revealed, the one destined for destruction. He opposes and exalts himself above every so-called god or object of worship, so that he takes his seat in the temple of God, declaring himself to be God. Do you not remember that I told you these things when I was still with you? And you know what is now restraining him, so that he may be revealed when his time comes. For the mystery of lawlessness is already at work, but only until the one who now restrains it is removed. And then the lawless one will be revealed, whom the Lord Jesus will destroy with the breath of his mouth, annihilating him by the manifestation of his coming. The coming of the lawless one is apparent in the working of Satan, who uses all power, signs, lying wonders, and every kind of wicked deception for those who are perishing, because they refused to love the truth and so be saved. For this reason God sends them a powerful delusion, leading them to believe what is false, so that all who have not believed the truth but took pleasure in unrighteousness will be condemned.
One day, as he was teaching the people in the temple and telling the good news, the chief priests and the scribes came with the elders and said to him, ‘Tell us, by what authority are you doing these things? Who is it who gave you this authority?’ He answered them, ‘I will also ask you a question, and you tell me: Did the baptism of John come from heaven, or was it of human origin?’ They discussed it with one another, saying, ‘If we say, “From heaven,” he will say, “Why did you not believe him?” But if we say, “Of human origin,” all the people will stone us; for they are convinced that John was a prophet.’ So they answered that they did not know where it came from. Then Jesus said to them, ‘Neither will I tell you by what authority I am doing these things.’
