The opening clause of this chapter sets before us the basis of all the privileges and responsibilities of the Israel of God. It is a familiar thought amongst us that we must be in a relationship before we can know the affections or discharge the duties which belong to it. This is a plain and undeniable truth. If a man were not a father, no amount of argument or explanation could make him understand the feelings or affections of a father's heart; but the very moment he enters upon the relationship, he knows all about them.

Thus it is as to every relationship and position, and thus it is in the things of God. We cannot understand the affections or the duties of a child of God until we are on the ground. We must be Christians before we can perform Christian duties. Even when we are Christians, it is only by the gracious aid of the Holy Ghost that we can walk as such; but clearly, if we are not on Christian ground, we can know nothing of Christian affections or Christian duties. This is so obvious that argument is needless.

Now, most evidently, it is God's prerogative to declare how His children ought to conduct themselves, and it is their high privilege and holy responsibility to seek, in all things, to meet His gracious approval. "Ye are the children of the Lord your God: ye shall not cut yourselves." They were not their own; they belonged to Him, and therefore they had no right to cut themselves or disfigure their faces for the dead. Nature, in its pride and self-will, might say, Why may we not do like other people? What harm can there be in cutting ourselves, or making a baldness between our eyes? It is only an expression of grief, an affectionate tribute to our loved departed ones. Surely there can be nothing morally wrong in such a suited expression of sorrow.

To all this there was one simple but conclusive answer—"Ye are the children of the Lord your God." This fact altered every thing. The poor ignorant and uncircumcised Gentiles around them might cut and disfigure themselves, inasmuch as they knew not God, and were not in relationship to Him; but as for Israel, they were on the high and holy ground of nearness to God, and this one fact was to give tone and character to all their habits. They were not called upon to adopt or refrain from any particular habit or custom in order to be the children of God. This would be, as we say, beginning at the wrong end; but being His children, they were to act as such.

"Thou art a holy people unto the Lord thy God." He does not say, Ye ought to be a holy people. How could they ever make themselves a holy people, or a peculiar people, unto Jehovah? Utterly impossible. If they were not His people, no efforts of theirs could ever make them such. But God, in His sovereign grace, in pursuance of His covenant with their fathers, had made them His children, made them a peculiar people above all the nations that were upon the earth. Here was the solid foundation of Israel's moral edifice. All their habits and customs, all their doings and ways, their food and their clothing, what they did and what they did not do—all was to flow out of the one grand fact, with which they had no more to do than with their natural birth, namely, that they actually were the children of God, the people of His choice, the people of His own special possession.

Now, we cannot but acknowledge it to be a privilege of the very highest order to have the Lord so near to us, and so interested in all our habits and ways. To mere nature, no doubt—to one who does not know the Lord—is not in relationship to Him, the very idea of His holy presence, or of nearness to Him, would be simply intolerable: but to every true believer—every one who really loves God, it is a most delightful thought to have Him near us, and to know that He interests Himself in all the most minute details of our personal history and most private life; that He takes cognizance of what we eat and what we wear; that He looks after us by day and by night, sleeping and waking, at home and abroad; in short, that His interest in and care for us go far beyond those of the most tender, loving mother for her babe.

All this is perfectly wonderful; and surely, if we only realized it more fully, we should live a very different sort of life, and have a very different tale to tell. What a holy privilege—what a precious reality, to know that our loving Lord is about our path by day, and about our bed by night; that His eye rests upon us when we are dressing in the morning, when we sit down to our meals, when we go about our business, and in all our intercourse from morning till night! May the sense of this be a living and abiding power in the heart of every child of God on the face of the earth.

From verse 3 to 20, we have the law as to clean and unclean beasts, fishes, and fowls. The leading principles as to all these have already come under our notice in the eleventh chapter of Leviticus;[14] but there is a very important difference between the two scriptures. The instructions in Leviticus are given primarily to Moses and Aaron; in Deuteronomy, they are given directly to the people. This is perfectly characteristic of the two books. Leviticus may be specially termed, The priest's guide-book. In Deuteronomy, the priests are almost entirely in the back-ground, and the people are prominent. This is strikingly apparent all through the book, so that there is not the slightest foundation for the idea that Deuteronomy merely repeats Leviticus. Nothing can be further from the truth. Each book has its own peculiar province, its own design, its own work. The devout student sees and owns this with deep delight. Infidels are willfully blind, and can see nothing.

In verse 21 of our chapter, the marked distinction between the Israel of God and the stranger is strikingly presented.—"Ye shall not eat of any thing that dieth of itself; thou shalt give it unto the stranger that is in thy gates, that he may eat it; or thou mayest sell it unto an alien; for thou art a holy people unto the Lord thy God." The grand fact of Israel's relationship to Jehovah marked them off from all the nations under the sun. It was not that they were, in themselves, a whit better or holier than others; but Jehovah was holy, and they were His people. "Be ye holy, for I am holy."

Worldly people often think that Christians are very pharisaic in separating themselves from other people, and refusing to take part in the pleasures and amusements of the world; but they do not really understand the question. The fact is, for a Christian to participate in the vanities and follies of a sinful world would be, to use a typical phrase, like an Israelite eating that which had died of itself. The Christian, thank God, has gotten something better to feed upon than the poor dead things of this world. He has the Living Bread that came down from heaven—the true Manna; and not only so, but he eats of "the old corn of the land of Canaan," type of the risen and glorified Man in the heavens. Of these most precious things the poor unconverted worldling knows absolutely nothing, and hence he must feed upon what the world has to offer him. It is not a question of the right or the wrong of things looked at in themselves. No one could possibly have known aught about the wrong of eating of any thing that had died of itself if God's word had not settled it.
