171 And Abram is a son of ninety and nine years, and Jehovah appeareth unto Abram, and saith unto him, 'I 'am' God Almighty, walk habitually before Me, and be thou perfect; 2 and I give My covenant between Me and thee, and multiply thee very exceedingly.' 3 And Abram falleth upon his face, and God speaketh with him, saying,
4 'I—lo, My covenant 'is' with thee, and thou hast become father of a multitude of nations; 5 and thy name is no more called Abram, but thy name hath been Abraham, for father of a multitude of nations have I made thee; 6 and I have made thee exceeding fruitful, and made thee become nations, and kings go out from thee.
7 'And I have established My covenant between Me and thee, and thy seed after thee, to their generations, for a covenant age-during, to become God to thee, and to thy seed after thee; 8 and I have given to thee, and to thy seed after thee, the land of thy sojournings, the whole land of Canaan, for a possession age-during, and I have become their God.'

(Read Genesis 17:1-6)
The covenant was to be accomplished in due time. The promised Seed was Christ, and Christians in him. And all who are of faith are blessed with faithful Abram, being partakers of the same covenant blessings. In token of this covenant his name was changed from Abram, "a high father," to Abraham, "the father of a multitude." All that the Christian world enjoys, it is indebted for to Abraham and his Seed.
Commentary on Genesis 17:7-14
(Read Genesis 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.
