and to give us who are afflicted relief when the Lord Jesus is revealed from heaven with his mighty angels

when he comes to be glorified by his saints and to be regarded with wonder on that day by all who have believed including you, because you believed our testimony.

not to be so quickly upset or alarmed when someone claims that we said, either by some spirit, conversation, or letter that the Day of the Lord has already come.

Don't you remember that I repeatedly told you about these things when I was still with you?

You know what it is that is now holding him back, so that he will be revealed when his time comes.
