There is something wonderfully vivid in the idea which Paul gives of his love for the Thessalonians. His mind is full of them; he imagines all the circumstances of trial and danger in which they may be placed; if he could only be with them at need! He seems to follow them as a woman follows with her thoughts the son who has gone alone to a distant town; she remembers him when he goes out in the morning, pities him if there are any circumstances of hardship in his work, pictures him busy in shop or office or street, looks at the clock when he ought to be home for the day; wonders where he is, and with what companions, in the evening; and counts the days till she will see him again. The Christian love of the Apostle, which had no basis at all in nature, was as real as this; and it is a pattern for all those who try to serve others in the gospel. The power of the truth, as far as its ministers are concerned, depends on its being spoken in love; unless the heart of the preacher or teacher is really pledged to those to whom he speaks, he cannot expect but to labour in vain.
Paul is anxious that the Thessalonians should understand the strength of his feeling. It was no passing fancy. On two separate occasions he had determined to revisit them, and had felt, apparently, some peculiar malignity in the circumstances which foiled him. "Satan," he says, "hindered us."
This is one of the expressions which strike us as remote from our present modes of thought. Yet it is not false or unnatural. It belongs to that profound biblical view of life, according to which all the opposing forces in our experience have at bottom a personal character. We speak of the conflict of good and evil, as if good and evil were powers with an existence of their own, but the moment we think of it we see that the only good force in the world is the force of a good will, and the only bad force the force of a bad will; in other words, we see that the conflict of good and evil is essentially a conflict of persons. Good persons are in conflict with bad persons; and so far as the antagonism comes to a head, Christ, the New Testament teaches, is in conflict with Satan. These persons are the centres of force on one side and on the other; and the Apostle discerns, in incidents of his life which have now been lost to us, the presence and working now of this, and now of that. An instructive illustration is really furnished by a passage in Acts which seems at the first glance of a very different purport. It is in the 16th chap., vv. 6-10, in which the historian describes the route of the Apostle from the East to Europe. "They were _forbidden of the Holy Ghost_ to speak the word in Asia" ... "they assayed to go into Bithynia; and _the Spirit of Jesus suffered them not_" ... Paul saw a vision, after which they "sought to go forth into Macedonia, _concluding that God had called them_ to preach the gospel unto them." Here, we might almost say, the three Divine Persons are referred to as the source of intimations directing and controlling the course of the gospel; yet it is evident, from the last mentioned, that such intimations might come in the shape of any event providentially ordered, and that the interpretation of them depended on those to whom they came. The obstacles which checked Paul's impulse to preach in Asia and in Bithynia he recognised to be of Divine appointment; those which prevented him from returning to Thessalonica were of Satanic origin. We do not know what they were; perhaps a plot against his life, which made the journey dangerous; perhaps some sin or scandal that detained him in Corinth. At all events it was the doing of the enemy, who in this world, of which Paul does not hesitate to call him the god, has means enough at his disposal to foil, though he cannot overcome, the saints.
