17 (As it is written, I have made thee a father of many nations,) before him whom he believed, even God, who quickeneth the dead, and calleth those things which be not as though they were. (Romans 4:17 KJV)
William Burkitt’s Commentary
Apostle Paul, in this and the following verses, enters upon a high commendation of Abraham’s faith, magnifying and extolling the same, for and upon account of sundry excellencies which are found in it.
And here, 1. He takes notice how Abraham’s faith was strongly acted and exercised on the Almighty power of God: He believed in God, who quickeneth the dead, and calleth those things which are not, as though they were: That is, The Lord having promised to make Abraham the father of many nations, which he had no seed, nor was ever likely to have any; he believed the thing to be both credible and possible because God had spoken it, how improbable soever. And although with respect to generation, he looked upon Sarah’s body, and his own, as good as dead; for she was barren and past bearing, and he was a hundred years old, and past all hopes of having a child; yet he exercised his faith on the promise and power of God, who quickeneth the dead, that is, his own dead body, and Sarah’s barren womb; and called those things which be not, that is, the Gentiles which were not then a people, as if they were.
Learn hence, That it is a noble act and exercise of faith to believe God on his bare word and to assent to truth, though never so improbable. As whatever God does is good, because he does it; so whatever God says is true, because he speaks it: And accordingly, faith, which is an assent of the understanding to what God reveals, depends upon the veracity of God for making good his own word, and fulfilling his own promise. Faith though never so improbable; it puts men upon duties, though seemingly unreasonable (witness Abraham’s offering up of Isaac); and it enables to sufferings, be they never so afflictive. But from believing plain contradictions and impossibilities as the church of Rome would have us in the point of transubstantiation; Faith desires there to be excused.
Observe here, 2. That as Abraham’s faith exceedingly honoured God; so God highly honours Abraham’s faith, making him like himself, a father of many nations. As God is a universal Father, not of one, but of all nations, so was Abraham; as God is their spiritual father, not by carnal generation, so was Abraham: God made faithful Abraham like himself, a father, not of this or that nation only, but universally of all believers, among all nations, believing after his example. Thus Abraham’s faith honours God, and God honours Abraham’s faith, styling him as the father of the Faithful throughout all generations.
