Commentary
Matthew Henry on Romans 4:17-22
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 bre…
And being fully persuaded, &c.--that is, the glory which Abraham's faith gave to God consisted in this, that, firm in the persuasion of God's ability to fulfil his promise, no difficulties shook him.
Adam Clarke on Romans 4:21
And being fully persuaded - πληροφορηθεις, his measure: his soul was full of confidence, that the truth of God bound him to fulfill his promise and his power enabled him to do it.
John Gill on Romans 4:21
And being fully persuaded,.... He had not only faith, a strong faith, but full assurance of faith:
that what he God had promised; though it was so long ago, and there were so many difficulties in the way;
he was able, being the Lord God Almighty,
to perform; so his faith rested upon the power of God, with whom nothing is impossible.
John Calvin on Romans 4:19-22
Romans 4:19-22
19. And being not weak in faith, he considered not his own body now dead, when he was about an hundred years old, neither yet the deadness of Sarah's womb:
19. Ac fide minime debilitatus, non consideravit suum ipsius corpus jam emortuum, centenaries quum fere esset, nec emortuam vulvam Sar?:
20. He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God;
20. Nec vero in Dei promissionem nec emortuam vulvam Sarre: per incredulitatem disquisivit; sed roboratus est fide, tribuens gloriam Deo;
21. And being fully persuaded that, what he had promised, he was able also to perform.
21. Ac certe persuasus, quod ubi quid promisit, possit…
The Church Fathers
Abraham thanked God as if he had already received the gift.
God brings about the faith of the Gentiles, because he is able to perform what he has promised. If it is God who produces our faith, acting in a wondrous manner in our hearts so that we believe, surely we should not fear that he cannot do the entire work.
Abstaining then from curious questionings is glorifying God, as indulging in them is transgressing. But if by entering into curious questions, and searching out things below, we fail to glorify Him, much more if we be over curious in the matter of the Lord's generation, shall we suffer to the utmost for our insolence. For if the type of the resurrection is not to be searched into, much less those untterable and awestriking subjects. And he does not use the word "believed" merely, but, "being fully persuaded." For such a thing is faith, it is clearer than the demonstration by reasons, and persuades more fully. For it is not possible for another reasoning succeeding to it to shake it afterwards. He indeed that is persuaded with words may have his persuasion altered too by them. But he that stays himself upon faith, hath henceforward fortified his hearing against words that may do hurt to it. Having said then, that he was justified by faith, he shows that he glorified God by that faith; which is a thing specially belonging to a good life. For, "Let your light so shine before men, that they may see your good works, and glorify your Father Which is in heaven." But lo! this is shown also to belong to faith! Again, as works need power, so doth faith. For in their case the body often shareth the toil, but in the faith the well-doing belongeth to the soul alone. And so the labor is greater, since it has no one to share the struggles with it.
