When Paul wrote this Epistle, the Jews were the great enemies of the gospel; it was they who persecuted him from city to city, and roused against him everywhere the malice of the heathen; hostility to God was incarnated, if anywhere, in them. They alone, because of their spiritual privileges, were capable of the deepest spiritual sin. Already in the First Epistle he has denounced them as the murderers of the Lord Jesus and of their own prophets, a race that please not God and are contrary to all men, sinners on whom the threatened wrath has come without reserve. In the passage before us the course is outlined of that wickedness against which the wrath was revealed. The people of God, as they called themselves, fall definitely away from God; the monster of lawlessness who rises from among them can only be pictured in the words in which prophets pourtrayed the impiety and presumption of a heathen king; he thrusts God aside, and claims to be God himself.
There is only one objection to this interpretation of the Apostle's words, namely, that they have never been fulfilled. Some will think that objection final; and some will think it futile: I agree with the last. It proves too much; for it lies equally against every other interpretation of the words, however ingenious, as well as against the simple and natural one just given. It lies, in some degree, against almost every prophecy in the Bible. No matter what the apostasy, and the man of sin, are taken to be, nothing has ever appeared in history which answers exactly to Paul's description. The truth is that inspiration did not enable the apostles to write history before it happened; and though this forecast of the Apostle's has a spiritual truth in it, resting as it does on a right perception of the law of moral development, the precise anticipation which it embodies was not destined to be realised. Further, it must have changed its place in Paul's own mind within the next ten years; for, as Dr. Farrar has observed, he barely alludes again to the Messianic surroundings (or antecedents) of a second personal advent. "He dwells more and more on the mystic oneness with Christ, less and less on His personal return. He speaks repeatedly of the indwelling presence of Christ, and the believer's incorporation with Him, and hardly at all of that visible meeting in the air which at this epoch was most prominent in his thoughts."
But, it may be said, if this anticipation was not to be fulfilled, is it not altogether deceptive? is it not utterly misleading that a prophecy should stand in Holy Scripture which history was to falsify? I think the right answer to that question is that there is hardly any prophecy in Holy Scripture which has not been in a similar way falsified, while nevertheless in its spiritual import true. The details of this prophecy of St. Paul were not verified as he anticipated, yet the soul of it was. The Advent was _not_ just then; it was delayed till a certain moral process should be accomplished; and this was what the Apostle wished the Thessalonians to understand. He did not know when it would be; but he could see so far into the law of God's working as to know that it would not come till the fulness of time; and he could understand that, where a final judgment was concerned, the fulness of time would not arrive till evil had had every opportunity, either to turn and repent, or to develop itself in the most utterly evil forms, and lie ripe for vengeance.
This is the ethical law which underlies the Apostle's prophecy; it is a law confirmed by the teaching of Jesus Himself, and illustrated by the whole course of history. The question is sometimes discussed whether the world gets better or worse as it grows older, and optimists and pessimists take opposite sides upon it. Both, this law informs us, are wrong. It does not get better only, nor worse only, but both. Its progress is not simply a progress in good, evil being gradually driven from the field; nor is it simply a progress in evil, before which good continually disappears: it is a progress in which good and evil alike come to maturity, bearing the ripest fruit, showing all that they can do, proving their strength to the utmost against each other; the progress is not in good in itself, nor in evil in itself, but in the antagonism of the one to the other. This is the same truth which we are taught by our Lord in the parable of the wheat and the tares: "Let both grow together until the harvest: and in the time of harvest I will say to the reapers, Gather up first the tares," etc. _In the time of harvest_: not till all is ripe for judgment, not till the wheat and the tares alike have shown all that is in them, will the judgment come. This is what St. Paul understood, and what the Thessalonians did not understand; and if his ignorance of the scale of the world, and the scale of God's purposes, made him apply this law to the riddle of history hastily, with a result which the event has not justified, that is nothing to the prejudice of the law itself, which was true when he applied it with his imperfect knowledge, and is true for application still.
