‘Do you not remember that while I was still with you, I was telling you these things?

And you know what restrains him now, so that in his time he will be revealed.

For the mystery of lawlessness is already at work; only he who restrains will do so until he is taken out of the way.

Then that lawless one will be revealed whom the Lord will slay 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 signs and false wonders.

and with all the deception of wickedness for those who perish, because they did not receive the love of the truth so as to be saved.’

2 Thessalonians 2:5-10
