"Finally then, brethren, we beseech and exhort you in the Lord Jesus, that, as ye received of us how ye ought to walk and to please God, even as ye do walk,—that ye abound more and more. For ye know what charge we gave you through the Lord Jesus. For this is the will of God, even your sanctification, that ye abstain from fornication; that each one of you know how to possess himself of his own vessel in sanctification and honour, not in the passion of lust, even as the Gentiles which know not God; that no man transgress, and wrong his brother in the matter: because the Lord is an avenger in all these things, as also we forewarned you and testified. For God called us not for uncleanness, but in sanctification. Therefore he that rejecteth, rejecteth not man, but God, who giveth His Holy Spirit unto you."—1 Thess. iv. 1-8 (R.V.).

THE "finally" with which this chapter opens is the beginning of the end of the Epistle. The personal matter which has hitherto occupied us was the immediate cause of the Apostle's writing; he wished to open his heart to the Thessalonians, and to vindicate his conduct against the insidious accusations of his enemies; and having done so, his main purpose is fulfilled. For what remains—this is the meaning of "finally"—he has a few words to say suggested by Timothy's report upon their state.

The previous chapter closed with a prayer for their growth in love, with a view to their establishment in holiness. The prayer of a good man avails much in its working; but his prayer of intercession cannot secure the result it seeks without the co-operation of those for whom it is made. Paul, who has besought the Lord on their behalf, now beseeches the Thessalonians themselves, and exhorts them in the Lord Jesus, to walk as they had been taught by him. The gospel, we see from this passage, contains a new law; the preacher must not only do the work of an evangelist, proclaiming the glad tidings of reconciliation to God, but the work of a catechist also, enforcing on those who receive the glad tidings the new law of Christ. This is in accordance with the final charge of the Saviour: "Go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Ghost, teaching them to observe all things whatsoever I have commanded you." The Apostle had followed this Divine order; he had made disciples in Thessalonica, and then he had taught them how to walk and to please God. We who have been born in a Christian country, and bred on the New Testament, are apt to think that we know all these things; our conscience seems to us a sufficient light. We ought to know that, though conscience is universal in the human race, and everywhere distinguishes between a right and a wrong, there is not one of our faculties which is more in need of enlightenment. No one doubts that men who have been converted from heathenism, like the Thessalonians, or the fruits of modern missions in Nyassaland or Madagascar, need to be taught what kind of life pleases God; but in some measure we all need such teaching. We have not been true to conscience; it is set in our human nature like the unprotected compass in the early iron ships: it is exposed to influences from other parts of our nature which bias and deflect it without our knowledge. It needs to be adjusted to the holy will of God, the unchangeable standard of right, and protected against disturbing forces. In Thessalonica Paul had laid down the new law, he says, through the Lord Jesus. If it had not been for Him, we should have been without the knowledge of it altogether; we should have had no adequate conception of the life with which God is well pleased. But such a life is exhibited to us in the Gospels; its spirit and requirements can be deduced from Christ's example, and are explicitly set forth in His words. He left us an example, that we should follow in His steps. "Follow Me," is the sum of His commandments; the one all-embracing law of the Christian life.

One of the subjects of which we should gladly know more is the use of the Gospels in the early Church; and this passage gives us one of the earliest glimpses of it. The peculiar mention of the Lord Jesus in the second verse shows that the Apostle used the words and example of the Master as the basis of his moral teaching; the mind of Christ is the norm for the Christian conscience. And if it be true that we still need enlightenment as to the claims of God and the law of life, it is here we must seek it. The words of Jesus have still their old authority. They still search our hearts, and show us all things that ever we did, and their moral worth or worthlessness. They still reveal to us unsuspected ranges of life and action in which God is not yet acknowledged. They still open to us gates of righteousness, and call on us to enter in, and subdue new territories to God. The man who is most advanced in the life which pleases God, and whose conscience is most nearly identical with the mind of Christ, will be the first to confess his constant need of, and his constant dependence upon, the word and example of the Lord Jesus.

In addressing the Thessalonians, Paul is careful to recognise their actual obedience. Ye do walk, he writes, according to this rule. In spite of sins and imperfections, the church, as a whole, had a Christian character; it was exhibiting human life in Thessalonica on the new model; and while he hints that there is room for indefinite progress, he does not fail to notice their present attainments. That is a rule of wisdom, not only for those who have to censure or to teach, but for all who wish to judge soberly the state and prospects of the Church. We know the necessity there is for abounding more and more in Christian obedience; we can see in how many directions, doctrinal and practical, that which is lacking in faith requires to be perfected; but we need not therefore be blind to the fact that it is in the Church that the Christian standard is held up, and that continuous, and not quite unsuccessful efforts, are made to reach it. The best men in a community, those whose lives come nearest to pleasing God, are to be found among those who are identified with the gospel; and if the worst men in the community are also found in the Church at times, that is because the corruption of the best is worst. If God has not cast off His Church altogether, He is teaching her to do His will.

"For this," the Apostle proceeds, "is the will of God, even your sanctification." It is assumed here that the will of God is the law, and ought to be the inspiration, of the Christian. God has taken him out of the world that he may be His, and live in Him and for Him. He is not his own any longer; even his will is not his own; it is to be caught up and made one with the will of God; and that is sanctification. No human will works apart from God to this end of holiness. The other influences which reach it, and bend it into accord with them, are from beneath, not from above; as long as it does not recognise the will of God as its rule and support, it is a carnal, worldly, sinful will. But the will of God, to which it is called to submit, is the saving of the human will from this degradation. For the will of God is not only a law to which we are required to conform, it is the one great and effective moral power in the universe, and it summons us to enter into alliance and co-operation with itself. It is not a dead thing; it is God Himself working in us in furtherance of His good pleasure. To tell us what the will of God is, is not to tell us what is against us, but what is on our side; not the force which we have to encounter, but that on which we can depend. If we set out on an un-Christian life, on a career of falsehood, sensuality, worldliness, God is against us; if we go to perdition, we go breaking violently through the safeguards with which He has surrounded us, overpowering the forces by which He seeks to keep us in check; but if we set ourselves to the work of sanctification, He is on our side. He works in us and with us, because our sanctification is His will. Paul does not mention it here to dishearten the Thessalonians, but to stimulate them. Sanctification is the one task which we can face confident that we are not left to our own resources. God is not the taskmaster we have to satisfy out of our own poor efforts, but the holy and loving Father who inspires and sustains us from first to last. To fall in with His will is to enlist all the spiritual forces of the world in our aid; it is to pull with, instead of against, the spiritual tide.

In the passage before us the Apostle contrasts our sanctification with the cardinal vice of heathenism, impurity. Above all other sins, this was characteristic of the Gentiles who knew not God. There is something striking in that description of the pagan world in this connection: ignorance of God was at once the cause and the effect of their vileness; had they retained God in their knowledge, they could never have sunk to such depths of shame; had they shrunk from pollution with instinctive horror, they would never have been abandoned to such ignorance of God. No one who is not familiar with ancient literature can have the faintest idea of the depth and breadth of the corruption. Not only in writers avowedly immoral, but in the most magnificent works of a genius as lofty and pure as Plato, there are pages that would stun with horror the most hardened profligate in Christendom. It is hardly an exaggeration to say that on the whole matter in question the heathen world was without conscience: it had sinned away its sense of the difference between right and wrong; to use the words of the Apostle in another passage, being past feeling men had given themselves up to work all manner of uncleanness. They gloried in their shame. Frequently, in his epistles, Paul combines this vice with covetousness,—the two together representing the great interests of life to the ungodly, the flesh and the world. Those who do not know God and live for Him, live, as he saw with fearful plainness, to indulge the flesh and to heap up gain. Some think that in the passage before us this combination is made, and that ver. 6—"that no man go beyond and defraud his brother in any matter"—is a prohibition of dishonesty in business; but that is almost certainly[13] a mistake. As the Revised Version shows, the Apostle is speaking of the matter in hand; in the Church especially, among brethren in Christ, in the Christian home, the uncleanness of heathenism can have no place. Marriage is to be sanctified. Every Christian, marrying in the Lord, is to exhibit in his home-life the Christian law of sanctification and noble self-respect.

The Apostle adds to his warning against sensuality the terrible sanction, "The Lord is an avenger in all these things." The want of conscience in the heathen world generated a vast indifference on this point. If impurity was a sin, it was certainly not a crime. The laws did not interfere with it; public opinion was at best neutral; the unclean person might presume upon impunity. To a certain extent this is the case still. The laws are silent, and treat the deepest guilt as a civil offence. Public opinion is indeed stronger and more hostile than it once was, for the leaven of Christ's kingdom is actively at work in society; but public opinion can only touch open and notorious offenders, those who have been guilty of scandal as well as of sin; and secrecy is still tempted to count upon impunity. But here we are solemnly warned that the Divine law of purity has sanctions of its own above any cognisance taken of offences by man. "The Lord is an avenger in all these things." "Because of these things cometh the wrath of God upon the sons of disobedience."

Is it not true? They are avenged on the bodies of the sinful. "Whatsoever a man soweth, that shall he also reap." The holy law of God, wrought into the very constitution of our bodies, takes care that we do not violate it without paying the penalty. If it is not at the moment, it is in the future, and with interest,—in premature old age; in the torpor which succeeds all spendthrift feats, excesses of man's prime; in the sudden break-down under any strain put on either physical or moral courage. They are avenged in the soul. Sensual indulgence extinguishes the capacity for feeling: the profligate man would love, but cannot; all that is inspiring, elevating, redeeming in the passions is lost to him; all that remains is the dull sense of that incalculable loss. Were there ever sadder lines written than those in which Burns, with his life ruined by this very thing, writes to a young friend and warns him against it?

This inward deadening is one of the most terrible consequences of immorality; it is so unexpected, so unlike the anticipations of youthful passion, so stealthy in its approach, so inevitable, so irreparable. All these sins are avenged also in the will and in the spiritual nature. Most men repent of their early excesses; some never cease to repent. Repentance, at least, is what it is habitually called; but that is not really repentance which does not separate the soul from sin. That access of weakness which comes upon the back of indulgence, that break-down of the soul in impotent self-pity, is no saving grace. It is a counterfeit of repentance unto life, which deludes those whom sin has blinded, and which, when often enough repeated, exhausts the soul and leaves it in despair. Is there any vengeance more terrible than that? When Christian was about to leave the Interpreter's house, "Stay," said the Interpreter, "till I have showed thee a little more, and after that thou shalt go on thy way." What was the sight without which Christian was not allowed to start upon his journey? It was the Man of Despair, sitting in the iron cage,—the man who, when Christian asked him "How camest thou in this condition?" made answer: "I left off to watch and be sober; I laid the reins upon the neck of my lusts; I sinned against the light of the word and the goodness of God; I have grieved the Spirit, and He is gone; I tempted the devil, and he is come to me; I have provoked God to anger, and He has left me; I have so hardened my heart that I cannot repent." This is no fancy picture: it is drawn to the life; it is drawn from the life; it is the very voice and tone in which many a man has spoken who has lived an unclean life under the cloak of a Christian profession. They who do such things do not escape the avenging holiness of God. Even death, the refuge to which despair so often drives, holds out no hope to them. There remaineth no more a sacrifice for sin, but a fearful expectation of judgment.

The Apostle dwells upon God's interest in purity. He is the avenger of all offences against it; but vengeance is His strange work. He has called us with a calling utterly alien to it,—not based on uncleanness or contemplating it, like some of the religions in Corinth, where Paul wrote this letter; but having sanctification, purity in body and in spirit, for its very element. The idea of "calling" is one which has been much degraded and impoverished in modern times. By a man's calling we usually understand his trade, profession, or business, whatever it may be; but our calling in Scripture is something quite different from this. It is our life considered, not as filling a certain place in the economy of society, but as satisfying a certain purpose in the mind and will of God. It is a calling in Christ Jesus; apart from Him it could not have existed. The Incarnation of the Son of God; His holy life upon the earth; His victory over all our temptations; His consecration of our weak flesh to God; His sanctification, by His own sinless experience, of our childhood, youth, and manhood, with all their unconsciousness, their bold anticipations, their sense of power, their bent to lawlessness and pride; His agony and His death upon the Cross; His glorious resurrection and ascension,—all these were necessary before we could be called with a Christian calling. Can any one imagine that the vices of heathenism, lust or covetousness, are compatible with a calling like this? Are they not excluded by the very idea of it? It would repay us, I think, to lift that noble word "calling" from the base uses to which it has descended; and to give it in our minds the place it has in the New Testament. It is God who has called us, and He has called us in Christ Jesus, and therefore called us to be saints. Flee, therefore, all that is unholy and unclean.

In the last verse of the paragraph the Apostle urges both his appeals once more: he recalls the severity and the goodness of God.

"Therefore he that rejecteth, rejecteth not man, but God". "Rejecteth" is a contemptuous word; in the margin of the Authorised Version it is rendered, as in some other places in Scripture, "despiseth." There are such things as sins of ignorance; there are cases in which the conscience is bewildered; even in a Christian community the vitality of conscience may be low, and sins, therefore, be prevalent, without being so deadly to the individual soul; but that is never true of the sin before us. To commit this sin is to sin against the light. It is to do what every one in contact with the Church knows, and from the beginning has known, to be wrong. It is to be guilty of deliberate, wilful, high-handed contempt of God. It is little to be warned by an apostle or a preacher; it is little to despise him: but behind all human warnings is the voice of God; behind all human sanctions of the law is God's inevitable vengeance; and it is that which is braved by the impure. "He that rejecteth, rejecteth not man, but God."

But God, we are reminded again in the last words, is not against us, but on our side. He is the Holy One, and an avenger in all these things; but He is also the God of Salvation, our deliverer from them all, who gives His Holy Spirit unto us. The words put in the strongest light God's interest in us and in our sanctification. It is our sanctification He desires; to this He calls us; for this He works in us. Instead of shrinking from us, because we are so unlike Him, He puts His Holy Spirit into our impure hearts, He puts His own strength within our reach that we may lay hold upon it, He offers us His hand to grasp. It is this searching, condescending, patient, omnipotent love, which is rejected by those who are immoral. They grieve the Holy Spirit of God, that Spirit which Christ won for us by His atoning death, and which is able to make us clean. There is no power which can sanctify us but this; nor is there any sin which is too deep or too black for the Holy spirit to overcome. Hearken to the words of the Apostle in another place: "Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with men, nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the Kingdom of God. And such were some of you: but ye were washed, but ye were sanctified, but ye were justified in the Name of the Lord Jesus Christ, and in the Spirit of our God."
