This defence is needed, for an “evil day” is at hand! This emphatic reference points to something more definite than the general day of temptation that is co-extensive with our earthly life. St Paul foresaw a crisis of extreme danger impending over the young Church of Christ. The prophecies of Jesus taught His disciples, from the first, that His kingdom could only prevail by means of a severe conflict, and that some desperate struggle would precede the final Messianic triumph. This prospect looms before the minds of the New Testament writers, as “the day of Jehovah” dominated the imagination of the Hebrew prophets. Paul’s apocalypse in 1 and 2 Thessalonians is full of reminiscences of Christ’s visions of judgement. It culminates in the prediction of the evil day of Antichrist, which is to usher in the second, glorious coming of the Lord Jesus. The consummation, as the apostle was then inclined to think, might arrive within that generation (1 Thess. iv. 15, 17), although he declares its times and seasons wholly unknown. In his later epistles, and in this especially, it is clear that he anticipated a longer duration for the existing order of things; and “the evil day” for which the Asian Churches are to prepare can scarcely have denoted, to the apostle’s mind, the final day of Antichrist, though it may well be an epoch of similar nature and a token and shadow of the last things. In point of fact, a great secular crisis was now approaching. The six years (64-70 after Christ) extending from the fire of Rome to the fall of Jerusalem, were amongst the most fateful and calamitous recorded in history. This period was, in a very real sense, the day of judgement for Israel and the ancient world. It was a foretaste of the ultimate doom of the kingdom of evil amongst men; and through it Christ appears to have looked forward to the end of the world. Already “the days are evil” (v. 16); and “the evil day” is at hand--a time of terror and despair for all who have not a firm faith in the kingdom of God. Two chief characteristics marked this crisis, as it affected the people of Christ: _persecution from without_, and _apostasy within the Church_ (Matt. xxiv. 5, 8-12). To the latter feature St Paul refers elsewhere.[170] Of persecution he took less account, for this was indeed his ordinary lot, and had already visited his Churches; but it was afterwards to assume a more violent and appalling form.
