The heartiness with which he speaks here justifies the inference that he had had experiences of an opposite and disappointing kind. Twice in Asia (Acts xvi. 6 f.) he had been forbidden by the Spirit to preach at all; he could not argue that the people so passed by were specially favoured of God. Often, especially in his intercourse with the Jews, he must have spoken, like Isaiah, with the depressing consciousness that it was all in vain; that the sole issue would be to blind their eyes and harden their hearts and seal them up in impenitence. In Corinth, just before writing this letter, he had come forward with unusual trepidation—in weakness and fear and much trembling; and though there also the Holy Spirit and a divine power brought home the gospel to men's hearts, he seems to have been so far from that inward assurance which he enjoyed at Thessalonica, that the Lord appeared to him in a vision by night to reveal the existence of an election of grace even in Corinth. "Fear not: I have much people in this city." In Thessalonica he had no such sinking of heart. He came thither, as he hoped to go to Rome, in the fulness of the blessing of Christ (Rom. xv. 29). He knew in himself that God had given it to him to be a true minister of His grace; he was full of power by the Spirit of the Lord. That is why he says so confidently, "Knowing your election."
The Apostle explains himself more precisely when he writes, "not in word only, but in power and in the Holy Ghost and in much assurance." The gospel must come in word at least; but what a profanation it is to preach it only in word. Not preachers only, but all Christians, have to be on their guard, lest familiarity rob the great words of the gospel of their reality, and they themselves sink into that worst atheism which is for ever handling holy things without feeling them. How easy is it to speak of God, Christ, redemption, atonement, sanctification, heaven, hell, and to be less impressed and less impressive than if we were speaking of the merest trivialities of every-day life. It is hard to believe that an apostle could have seen such a possibility even from afar; yet the contrast of "word" and "power" leaves no room to doubt that such is his meaning. Words alone are worthless. No matter how brilliant, how eloquent, how imposing they may be, they cannot do the work of an evangelist. The call to this requires "power."
No definition of power is given; we can only see that it is that which achieves spiritual results, and that the preacher is conscious of possessing it. It is not his own, certainly: it works through the very consciousness of his own want of power; "when I am weak, then am I strong." But it gives him hope and confidence in his work. Paul knew that it needed a stupendous force to make bad men good; the forces to be overcome were so enormous. All the sin of the world was arrayed against the gospel; all the dead weight of men's indifference, all their pride, all their shame, all their self-satisfaction, all their cherished wisdom. But he came to Thessalonica strong in the Lord, confident that his message would subdue those who listened to it; and therefore, he argued, the Thessalonians were the objects of God's electing grace.
"Power" stands side by side with the "Holy Ghost." In a sense, the Holy Ghost is the source of all spiritual virtues, and therefore of the very power of which we have been speaking; but the words are probably used here with some narrower meaning. The predominant use of the name in the New Testament bids us think of that divine fervour which the spirit kindles in the soul—that ardour of the new life which Christ Himself speaks of as fire. Paul came to Thessalonica aglow with Christian passion. He took that as a good omen in his work, a sign that God meant well to the Thessalonians. By nature men do not care passionately for each other as he cared for those to whom he preached in that city. They are not on fire with love, seeking each other's good in spiritual things; consumed with fervent longing that the bad should cease from their badness, and come to enjoy the pardon, the purity, and the company of Christ. Even in the heart of apostles—for though they were apostles they were men—the fire may sometimes have burned low, and a mission have been, by comparison, languid and spiritless; but at least on this occasion the evangelists were all on fire; and it assured them that God had a people waiting for them in the unknown city.
If "power" and the "Holy Ghost" are in some degree to be judged only by their effects, there can be no question that "much assurance," on the other hand, is an inner experience, belonging strictly to the self-consciousness of the preacher. It means a full and strong conviction of the truth of the gospel. We can only understand this by contrast with its opposite; "much assurance" is the counterpart of misgiving or doubt. We can hardly imagine an apostle in doubt about the gospel—not quite certain that Christ had risen from the dead; wondering whether, after all, His death had abolished sin. Yet these truths, which are the sum and substance of the gospel, seem, at times, too great for belief; they do not coalesce with the other contents of our mind; they do not weave easily into one piece with the warp and woof of our common thoughts; there is no common measure for them and the rest of our experience, and the shadow of unreality falls upon them. They are so great that it needs a certain greatness to answer to them, a certain boldness of faith to which even a true Christian may feel momentarily unequal; and while he is unequal, he cannot do the work of an evangelist. Doubt paralyses; God cannot work through a man in whose soul there are misgivings about the truth. At least, His working will be limited to the sphere of what is certain for him through whom He works; and if we would be effective ministers of the word, we must speak only what we are sure of, and seek the full assurance of the whole truth. No doubt such assurance has conditions. Unfaithfulness of one kind or another is, as our Lord teaches (John vii. 17), the source of uncertainty as to the truth of His word; and prayer, repentance, and obedience due, the way to certainty again. But Paul had never been more confident of the truth and power of his gospel than when he came to Thessalonica. He had seen it proved in Philippi, in conversions so dissimilar as those of Lydia and the jailor. He had felt it in his own heart, in the songs which God had given him in the night while he suffered for Christ's sake. He came among those whom he addresses confident that it was God's instrument to save all who believed. This is his last personal reason for believing the Thessalonians to be elect.
Strictly speaking, all this refers rather to the delivery of the message than to the messengers, to the preaching than to the preachers; but the Apostle applies it to the latter also. "Ye know," he writes, "what manner of men we showed ourselves toward you for your sakes." I venture to think[2] that the word rendered "we showed ourselves" has really the passive sense—"what God enabled us to be"; it is God's good will to the Thessalonians which is in view, and the Apostle infers that good will from the character which God enabled him and his friends to sustain for their sakes. Who could deny that God had chosen them, when He had sent them Paul and Silas and Timothy; not mere talkers, cold and spiritless, and dubious of their message; but men strong in spiritual force, in holy fervour, and in their grasp of the gospel? If that did not go to show that the Thessalonians were elect, what could?
II. The self-consciousness of the preachers, however, significant as it was, was no conclusive evidence. It only became such when their inspiration was caught by those who listened to them; and this was the case at Thessalonica. "Ye became imitators of us and of the Lord, having received the word in much affliction, with joy of the Holy Ghost." This peculiar expression implies that the signs of God's election were to be seen in the evangelists, and eminently in the Lord. Paul shrinks from making himself and his companions types of the elect, without more ado; they are such only because they are like Him, of whom it is written "Behold my servant whom I uphold; Mine elect, in whom My soul delighteth." He speaks here in the same strain as in 1 Cor. xi. 1: "Brethren, be ye imitators of me, even as I also am of Christ." They who have become like the Lord are marked out as the chosen of God.
But the Apostle does not rest in this generality. The imitation in question consisted in this—that the Thessalonians received the word in much affliction, with joy of the Holy Ghost. It is, of course, in the last part of the sentence that the point of comparison is found. In a sense it is true that the Lord Himself received the word which He spoke to men. "I do nothing of Myself," He says; "but as the Father hath taught Me, I speak these things" (John viii.
