Römer 4:17

As it is written, I have made thee a father - That Abraham's being a father of many nations has relation to the covenant of God made with him, may be seen, Gen 17:4, Gen 17:5 : Behold my covenant is with thee, and thou shalt be a father of many nations: neither shall thy name any more be called Abram; but thy name shall be Abraham, for a father of many nations have I made thee, i.e. he was constituted the head of many nations, the Gentile world, by virtue of the covenant, which God made then with him. God, who quickeneth the dead, etc. - God is the most proper object of trust and dependence; for being almighty, eternal, and unchangeable, he can even raise the dead to life, and call those things which be not as though they were. He is the Creator, he gave being when there was none; he can as infallibly assure the existence of those things which are not, as if they were already actually in being. And, on this account, he can never fail of accomplishing whatsoever he has promised.

As it is written, &c.-- (Gen 17:5). This is quoted to justify his calling Abraham the "father of us all," and is to be viewed as a parenthesis. before--that is, "in the reckoning of." him whom he believed--that is, "Thus Abraham, in the reckoning of Him whom he believed, is the father of us all, in order that all may be assured, that doing as he did, they shall be treated as he was." even God, quickeneth the dead--The nature and greatness of that faith of Abraham which we are to copy is here strikingly described. What he was required to believe being above nature, his faith had to fasten upon God's power to surmount physical incapacity, and call into being what did not then exist. But God having made the promise, Abraham believed Him in spite of those obstacles. This is still further illustrated in what follows.

Who against hope believed in hope,.... Abraham believed the promise of God, that he might become the father of many nations, being assisted by a supernatural aid: "in hope"; of the fulfilment of it by the grace and power of God: "against hope": against all visible, rational grounds of hope; Sarah's womb and his own body being dead, but inasmuch as God had said it, he believed: according to that which is spoken, so shall thy seed be; his faith rested upon the word of God, which showed the nature of it, and that it was of the right kind.

Having observed when Abraham was justified by faith, and why, for the honour of Abraham and for example to us who call him father, the apostle here describes and commends the faith of Abraham, where observe, I. Whom he believed: God who quickeneth. It is God himself that faith fastens upon: other foundation can no man lay. Now observe what in God Abraham's faith had an eye t - o that, certainly, which would be most likely to confirm his faith concerning the things promised: - 1. God who quickeneth the dead. It was promised that he should be the father of many nations, when he and his wife were now as good as dead (Heb 11:11, Heb 11:12), and therefore he looks upon God as a God that could breathe life into dry bones. He that quickeneth the dead can do any thing, can give a child to Abraham when he is old, can bring the Gentiles, who are dead in trespasses and sins, to a divine and spiritual life, Eph 2:1. Compare Eph 1:19, Eph 1:20. 2. Who calleth things which are not as though they were; that is, creates all things by the word of his power, as in the beginning, Gen 1:3; Co2 4:6. The justification and salvation of sinners, the espousing of the Gentiles that had not been a people, were a gracious calling of things which are not as though they were, giving being to things that were not. This expresses the sovereignty of God and his absolute power and dominion, a mighty stay to faith when all other props sink and totter. It is the holy wisdom and policy of faith to fasten particularly on that in God which is accommodated to the difficulties wherewith it is to wrestle, and will most effectually answer the objections. It is faith indeed to build upon the all-sufficiency of God for the accomplishment of that which is impossible to anything but that all-sufficiency. Thus Abraha…
