Since it is a righteous thing with God to repay affliction to those who afflict you,
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.
