Thirdly, the temporal and the spiritual are brought together. The land of promise is made sure to the heir of promise, "for a perpetual possession," and God engages to "be their God." The phrase "perpetual possession" has here two elements of meaning - first, that the possession, in its coming form of a certain land, shall last as long as the co-existing relations of things are continued; and, secondly, that the said possession in all the variety of its ever grander phases will last absolutely forever. Each form will be perfectly adequate to each stage of a progressive humanity. But in all its forms and at every stage it will be their chief glory that God is their God.

Everlasting possession - Here עולם olam appears to be used in its accommodated meaning, and signifies the completion of the Divine counsel in reference to a particular period or dispensation. And it is literally true that the Israelites possessed the land of Canaan till the Mosaic dispensation was terminated in the complete introduction of that of the Gospel. But as the spiritual and temporal covenants are both blended together, and the former was pointed out and typified by the latter, hence the word even here may be taken in its own proper meaning, that of ever-during, or eternal; because the spiritual blessings pointed out by the temporal covenant shall have no end. And hence it is immediately added, I will be their God, not for a time, certainly, but for ever and ever. See the note on Genesis 21:33.

And I will give unto thee, and to thy seed after thee,.... To him in right, and to them in possession, and for an inheritance:

the land wherein thou art a stranger; or "the land of sojournings" or "pilgrimages" (l), which were many; for he often removed from place to place, and sometimes sojourned in one place, and sometimes in another:

all the land of Canaan, for an everlasting possession; this respects only the natural seed of Abraham, and those in the line of Isaac and Jacob, to whom this land was given to hold for ever, in case they were obedient to the will of God; and therefore whenever they were disobedient, they were carried captive from it, as they are at this day; but when they shall be converted, they will return to this land and possess it to the end of the world; and which was a figure of the heavenly inheritance, which is an eternal one, and will be enjoyed by all his spiritual seed to all eternity:

and I will be their God; as he was to all the natural seed of Abraham in a spiritual sense, to whom the adoption belonged, and whom he chose and separated as a peculiar people to himself, and bestowed in providence many peculiar favours upon them, both in a civil and religious way; and as he is to all his spiritual seed in an evangelic sense, to whom he stands in the relation of their covenant God and Father in Christ, in whom he blesses them with all spiritual blessings, and will continue to be so unto death, and to all eternity.

(l) "terram peregrinationum tuarum", Pagninus, Montanus, &c.

And I will give unto thee, and to thy seed after thee, the land wherein thou art a stranger, all the land of Canaan, for an everlasting possession; and I will be their God.

17:8 And I will give thee Canaan for an everlasting possession - God had before promised this land to Abraham and his seed, Ge 15:18. But here, it is promised for an everlasting possession, as a type of heaven, that everlasting rest which remains for the people of God. This is that better country to which Abraham had an eye, and the grant of which was that which answered the vast extent of that promise, that God would be to them a God; so that if God had not designed this, he would have been ashamed to be called their God, Heb 11:16. As the land of Canaan was secured to the seed of Abraham, according to the flesh; so heaven is secured to all his spiritual seed for a possession truly everlasting. The offer of this eternal life is made in the word, and confirmed by the sacraments, to all that are under the external administration of the covenant, and the earnest of it is given to all believers.

wherein...: Heb. of thy sojournings

8. I will give unto thee . the land-It had been previously promised to Abraham and his posterity (Ge 15:18). Here it is promised as an "everlasting possession," and was, therefore, a type of heaven, "the better country" (Heb 11:16).

17:7-14 The covenant of grace is from everlasting in the counsels of it, and to everlasting in the consequences of it. The token of the covenant was circumcision. It is here said to be the covenant which Abraham and his seed must keep. Those who will have the Lord to be to them a God, must resolve to be to him a people. Not only Abraham and Isaac, and his posterity by Isaac, were to be circumcised, but also Ishmael and the bond-servants. It sealed not only the covenant of the land of Canaan to Isaac's posterity, but of heaven, through Christ, to the whole church of God. The outward sign is for the visible church; the inward seal of the Spirit is peculiar to those whom God knows to be believers, and he alone can know them. The religious observance of this institution was required, under a very severe penalty. It is dangerous to make light of Divine institutions, and to live in the neglect of them. The covenant in question was one that involved great blessings for the world in all future ages. Even the blessedness of Abraham himself, and all the rewards conferred upon him, were for Christ's sake. Abraham was justified, as we have seen, not by his own righteousness, but by faith in the promised Messiah.
