dealing out [full and complete] vengeance to those who do not [seek to] know God and to those who ignore and refuse to obey the gospel of our Lord Jesus [by choosing not to respond to Him].

so that the name of our Lord Jesus will be glorified in you [by what you do], and you in Him, according to the [precious] grace of our God and the 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.

Do not allow anyone to deceive you in any way, for it will not occur until the rebellion comes first and the man of lawlessness becomes evident. [Note: This "rebellion" refers to a significant falling away from the teaching and practice of true Christianity (See I Tim. 4:1), characterized by the rise of an authoritarian religious leader]. This man is doomed to be destroyed

And we have become confident in the Lord regarding you, that ye both do, and will do, the things which we command.

[We did this], not because we did not have a right [to support], but so we could become an example for you to imitate.

But ye, brothers, do not become weary doing good.

And if any person does not obey our instructions, [given] in this letter, you should take note of him so that you do not associate with him, in hope that he will become ashamed [of his conduct].
