Therefore, we speak of you with pride among the churches of God for your steadfastness [your unflinching endurance, and patience] and your firm faith in the midst of all the persecution and [crushing] distress which you endure.

In flaming fire taking vengeance on them that know not God, and that obey not the gospel of our Lord Jesus Christ:

we request that you people do not become shaken up in your mind, nor alarmed, either by a spirit [i.e., by some prophetic prediction], or by a report, or by a letter supposedly from us, that the day of the Lord [i.e., when Jesus returns] has already come.

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 the lawless one will be revealed, whom the Lord Jesus will slay with the breath of his mouth, and wipe out by the appearance of his coming,

And for this cause, God will give them up to the power of deceit and they will put their faith in what is false:

But be not you, my brethren, discouraged from well-doing. And if any obey not our order,

And if any man obey not our word by this epistle, note that man, and have no company with him, that he may be ashamed.
