He will come in flames of fire to take vengeance on those who have no knowledge of God, and do not obey the Good News as to Jesus, our Lord.

when he shall come to be glorified in his saints, and to be made marvelous in all them that believe: because our testimony that we had unto you, was believed even the same day that we preached it.

not to be quickly shaken in your mind, nor yet be troubled, either by spirit, or by word, or by letter as from us, saying that the day of the Lord had come.

Let no man deceive you by any means, for the Lord cometh not, except there come a departing first, and that that sinful man be opened, the son of perdition;

who is opposing and is raising himself up above all called God or worshipped, so that he in the sanctuary of God as God hath sat down, shewing himself off that he is God -- the day doth not come.

And then will come the revelation of that evil one, whom the Lord Jesus will put to death with the breath of his mouth, and give to destruction by the revelation of his coming;

in order that all may come under judgement who have refused to believe the truth and have taken pleasure in unrighteousness.

For it has come to our ears that there are some among you whose behaviour is uncontrolled, who do no work at all, but are over-interested in the business of others.
