not to be quickly shaken in your mind, nor yet be troubled, either by spirit, or by word, or by letter as from us, saying that the day of Christ had come.
as that the day of Christ is at hand; or is at this instant just now coming on; as if it would be within that year, in some certain month, and on some certain day in it; which notion the apostle would have them by no means give into, for these reasons, because should Christ not come, as there was no reason to believe he would in so short a time, they would be tempted to disbelieve his coming at all, at least be very indifferent about it; and since if it did not prove true, they might be led to conclude there was nothing true in the Christian doctrine and religion; and besides, such a notion of the speedy coming of Christ would tend to indulge the idle and disorderly persons among them in their sloth and negligence: and now for these, and for the weighty reasons he gives in the next verse, he dissuades them from imbibing such a tenet; for though the coming of Christ is sometimes said to be drawing nigh, and to be quickly, yet so it might be, and not at that instant; besides, such expressions are used with respect to God, with whom a thousand years are as one day, and one day as a thousand years; and because the Gospel times, or times of the Messiah, are the last days, there will be no other dispensation of things until the second coming of Christ; and chiefly they are used to keep up the faith, and awaken the hope and expectation of the saints with respect to it. The Alexandrian copy, and some others, read, "the day of the Lord"; and so the Vulgate Latin version; and accordingly the Syriac and Ethiopic versions, "the day of our Lord".
