John Calvin on Romans 4:17

17. Whom he believed, who quickens the dead, etc. In this circuitous form is expressed the very substance of Abraham’s faith, that by his example an opening might be made for the Gentiles. He had indeed to attain, in a wonderful way, the promise which he had heard from the Lord’s mouth, since there was then no token of it. A seed was promised to him as though he was in vigor and strength; but he was as it were dead. It was hence necessary for him to raise up his thoughts to the power of God, by which the dead are quickened. It was therefore not strange that the Gentiles, who were barren and dead, should be introduced into the same society. He then who denies them to be capable of grace, does wrong to Abraham, whose faith was sustained by this thought, — that it matters not whether he was dead or not who is called by the Lord; to whom it is an easy thing, even by a word, to raise the dead through his own power.

We have here also a type and a pattern of the call of us all, by which our beginning is set before our eyes, not as to our first birth, but as to the hope of future life, — that when we are called by the Lord we emerge from nothing; for whatever we may seem to be we have not, no, not a spark of anything good, which can render us fit for the kingdom of God. That we may indeed on the other hand be in a suitable state to hear the call of God, we must be altogether dead in ourselves. The character of the divine calling is, that they who are dead are raised by the Lord, that they who are nothing begin to be something through his power. The word call ought not to be confined to preaching, but it is to be taken, according to the usage of Scripture, for raising up; and it is intended to set forth more fully the power of God, who raises up, as it were by a nod only, whom he wills. The idea of commanding to existence, or of effecting, is given by many Commentators to the word καλοῦντος; but this seems not necessary. The simple notion of calling, naming, regarding, or representing, is more consistent with the passage, and with the construction of the sentence: and the various modes of rendering it, which critics have proposed, have arisen from not taking the word in its most obvious meaning. “The literal version is, and who calls things not existing as existing,” — και καλοῦντος τὰ μὴ ὄντα ὡς ὄντα. The reference is evidently to the declaration, “I have made thee the father of many nations.” This had then no real existence; but God represents it as having an existence already. Far-fetched meanings are sometimes adopted, when the plainest and the most obvious is passed by. — Ed.

Romans 4:18

18. Who against hope believed in hope, that he might become the father of many nations, according to that which was spoken, So shall thy seed be.

18. Qui præter (vel supra) spem super spe credidit, ut esset “Ut esset:” this may indeed be rendered according to our version, “that he might become;” but the drift of the comment seems to favor the other view, that he believed that he should be, and not that he believed in order to be, or that he might be, the father of many nations εἰς τὸ γενέσθαι ἀυτὸν, “that he should be,” is the rendering of Hammond, Doddridge, and Stuart; and it is indeed what is consistent with the drift of the passage, and with what is recorded in Genesis. Wolfius says, that εἰς here does not signify the final cause, but the subject or the object of faith and hope; Abraham believed the promise, that he should be the father of many nations. — Ed. pater multarum gentium, secundum quod dictum erat, Sic erit semen tuum.
