'But the Scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe.'—Gal. iii. 22.

The Apostle uses here a striking and solemn figure, which is much veiled for the English reader by the ambiguity attaching to the word 'concluded.' It literally means 'shut up,' and is to be taken in its literal sense of confining, and not in its secondary sense of inferring. So, then, we are to conceive of a vast prison-house in which mankind is confined. And then, very characteristically, the Apostle passes at once to another metaphor when he goes on to say 'under sin.' What a moment before had presented itself to his vivid imagination as a great dungeon is now represented as a heavy weight, pressing down upon those beneath; if, indeed, we are not, perhaps, rather to think of the low roof of the dark dungeon as weighing on the captives.

Further, he says that Scripture has driven men into this captivity. That, of course, cannot mean that revelation makes us sinners, but it does mean that it makes us more guilty, and that it declares the fact of human sinfulness as no other voice has ever done. And then the grimness of the picture is all relieved and explained, and the office ascribed to God's revelation harmonised with God's love, by the strong, steady beam of light that falls from the last words, which tell us that the prisoners have not been bound in chains for despair or death, but in order that, gathered together in a common doleful destiny, they may become recipients of a common blessed salvation, and emerge into liberty and light through faith in Jesus Christ.

So here are three things—the prison-house, its guardian, and its breaker. 'The Scripture hath shut up all under sin, in order that the promise by faith of Jesus Christ might be given unto all them that believe.'

I. First, then, note the universal prison-house.

Now the Apostle says two things—and we may put away the figure and look at the facts that underlie it. The one is that all sin is imprisonment, the other is that all men are in that dungeon, unless they have come out of it through faith in Jesus Christ.

All sin is imprisonment. That is the direct contrary of the notion that many people have. They say to themselves, 'Why should I be fettered and confined by these antiquated restrictions of a conventional morality? Why should I not break the bonds, and do as I like?' And they laugh at Christian people who recognise the limitations under which God's law has put them; and tell us that we are 'cold-blooded folks who live by rule,' and contrast their own broad 'emancipation from narrow prejudice.' But the reality is the other way. The man who does wrong is a slave in the measure in which he does it. If you want to find out—and mark this, you young people, who may be deceived by the false contrasts between the restraints of duty and the freedom of living a dissolute life—if you want to find out how utterly 'he that committeth sin is the slave of sin,' try to break it off, and you will find it out fast enough. We all know, alas! the impotence of the will when it comes to hand grips with some evil to which we have become habituated; and how we determine and determine, and try, and fail, and determine again, with no better result. We are the slaves of our own passions; and no man is free who is hindered by his lower self from doing that which his better self tells him he ought to do. The tempter comes to you, and says, 'Come and do this thing, just for once. You can leave off when you like, you know. There is no need to do it a second time.' And when you have done it, he changes his note, and says, 'Ah! you are in, and you cannot get out. You have done it once; and in my vocabulary once means twice, and once and twice mean always.'

Insane people are sometimes tempted into a house of detention by being made to believe that it is a grand mansion, where they are just going to pay a flying visit, and can come away when they like. But once inside the walls, they never get past the lodge gates any more. The foolish birds do not know that there is lime on the twigs, and their little feet get fastened to the branch, and their wings flutter in vain. 'He that committeth sin is the slave of sin—shut up,' dungeoned, 'under sin.'

But do not forget, either, the other metaphor in our text, in which the Apostle, with characteristic rapidity, and to the horror of rhetorical propriety, passes at once from the thought of a dungeon to the thought of an impending weight, and says, 'Shut up under sin.'

What does that mean? It means that we are guilty when we have done wrong; and it means that we are under penalties which are sure to follow. No deed that we do, howsoever it may fade from the tablets of our memory, but writes in visible characters, in proportion to its magnitude, upon our characters and lives. All human acts have perpetual consequences. The kick of the rifle against the shoulder of the man that fires it is as certain as the flight of the bullet from its muzzle. The chalk cliffs that rise above the Channel entomb and perpetuate the relics of myriads of evanescent lives; and our fleeting deeds are similarly preserved in our present selves. Everything that a man wills, whether it passes into external act or not, leaves, in its measure, ineffaceable impressions on himself. And so we are not only dungeoned in, but weighed upon by, and lie under, the evil that we do.
