2 Thessalonians 1:6

6To appoint affliction. We have already stated why it is that he makes mention of the vengeance of God against the wicked — that we may learn to rest in the expectation of a judgment to come, because God does not as yet avenge the wicked, while it is, nevertheless, necessary that they should suffer the punishment of their crimes. Believers, however, at the same time, understand by this that there is no reason why they should envy the momentary and evanescent felicity of the wicked, which will ere long be exchanged for a dreadful destruction. What he adds as to the rest of the pious, accords with the statement of Paul, (Acts 3:20,) where he calls the day of the last judgment the day of refreshing

In this declaration, however, as to the good and the bad, he designed to shew more clearly how unjust and confused the government of the world would be, if God did not defer punishments and rewards till another judgment, for in this way the name of God were a thing that was dead. (629) Hence he is deprived of his office and power by all that are not intent on that righteousness of which Paul speaks.

He adds with us, that he may gain credit to his doctrine from his experience of belief in his own mind; for he shews that he does not philosophize as to things unknown, by putting himself into the same condition, and into the same rank with them. We know, however, how much more authority is due to those who have, by long practice, been exercised in those things which they teach, and do not require from others anything but what they are themselves prepared to do. Paul, therefore, does not, while himself in the shade, give instructions to the Thessalonians as to how they should fight in the heat of the sun, but, fighting vigorously, exhorts them to the same warfare.
