Because of this, God sends them a working of error, that they should believe a lie;
 Everybody who has read Isaiah, Jeremiah, Ezekiel, and the lesser prophets knows what they tell us of the horrors for men when the day of Jehovah comes upon the earth, that it will be. a day of dismay and darkness, when all earthly things are utterly confused, and the people of God seem about to be swallowed up by their enemies. False doctrine ever sets one truth against another; and it was not wanting among the Thessalonians at this time. For some sought to persuade them that the day of the Lord was even then arrived. They probably argued that their troubles were part of the circumstances of that day. Certainly they sought to shake them by pretending that the day of the Lord was actually there. There was such fearful persecution and trouble among them, that this might be plausibly enough mixed up as supporting the idea that the day of the Lord was begun. For this false rumour seems to imply that they must have given some sort of figurative colour to "that day" (as it was certainly so used in Old Testament prophecy). At any rate, they must have supposed that "the day of the Lord" did not necessarily require the presence of the Lord Himself. In other words, they might think, is many Christians since have imagined, that a dreadful time of trouble must befall the world before the Lord comes to receive His own to himself above.
