Ver. 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."
How was it that he "believed in hope against hope?" It was against man's hope, in hope which is of God. (For he is showing the loftiness of the action, and leaving no room for disbelieving what is said.) Things which are contrary to one another, yet faith blends them together. But if he were speaking about such as were from Ishmael, this language would be superfluous: for it was not by faith but by nature that they were begotten. But he bringeth Isaac also before us. For it was not concerning those nations that he believed, but concerning him who was to be from his barren wife. If then it be a reward to be father of many nations, it would be so of those nations clearly of whom he so believed. For that you may know that he is speaking of them, listen to what follows.
Ver. 19. "And being not weak in faith, he considered [1313] his own body now dead."
Do you see how he gives the obstacles, as well as the high spirit of the righteous man which surmounts all? "Against hope," he says, was that which was promised: this is the first obstacle. For Abraham had no other person who had received a son in this way to look to. They that were after him looked to him, but he to no one, save to God only. And this is why he said, "against hope." Then, "his body now dead." This is a second. And, "the deadness of Sarah's womb." This is a third, aye and a fourth [1314] obstacle.
Ver. 20. "But he staggered not at the promise of God through unbelief."
For God neither gave any proof nor made any sign, but there were only bare words promising such things as nature did not hold out any hopes of. Yet still he says, "he staggered not." He does not say, "He did not disbelieve," but, "He staggered not," that is, he neither doubted nor hesitated though the hindrances were so great. From this we learn, that if God promise even countless impossibilities, and he that heareth doth not receive them, it is not the nature of things that is to blame, but the unreasonableness of him who receiveth them not. "But was strong in faith." See the pertinacity of Paul. [1315] For since this discourse was about them that work and them that believe, he shows that the believer works more than the other, and requires more power, and great strength, and sustains no common degree of labor. For they counted faith worthless, as having no labor in it. Insisting then upon this, he shows that it is not only he that succeeds in temperance, or any other virtue of this sort, but he that displays faith also who requires even greater power. For as the one needs strength to beat off the reasonings [1316] of intemperance, so hath the faithful also need of a soul endued with power, that he may thrust aside the suggestions of unbelief. How then did he become "strong?" By trusting the matter, he replies, to faith and not to reasonings: else he had fallen. But how came he to thrive in faith itself? By giving glory to God, he says.
Ver. 21. "And being fully persuaded that what He had promised, He was able also to perform."
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 unutterable and awestriking subjects. [1317] 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 [1318] 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." (Matt. v. 16.) 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. Do you observe how he shows that all that belonged to works attached to faith in a far greater degree, as having whereof to glory before God,--requiring power and labor,--and again, glorifying God? And after saying, that "what He had promised, He is able also to perform," he seems to me to speak beforehand of things to come. For it is not things present merely that He promises, but also things to come. For the present are a type of the other. It is then a sign of a weak, little, and pitiful mind not to believe. And so when any make faith a charge against us, let us make want of faith a charge against them in return, as pitiful, and little-minded, and foolish, and weak, and no better in disposition than asses. For as believing belongs to a lofty and high-born soul, so disbelieving doth to a most unreasonable and worthless one, and such as is sunken drowsily (katenenegmenes) into the senselessness of brutes. Therefore having left these, let us imitate the Patriarch, and glorify God as he gave Him glory. And what does it mean, gave Him glory? He held in mind His majesty, His boundless power. And having formed a just conception of Him, he was also "fully persuaded" about His promises.
Let us then also glorify Him by faith as well as by works, that we may also attain to the reward of being glorified by Him. "For them that glorify Me, I will glorify" (1 Sam. ii. 30), He says: and indeed, if there were no reward, the very privilege of glorifying God were itself a glory. For if men take a pride in the mere fact of speaking eulogies of kings, even if there be no other fruit of it; consider how glorious it must be, that our Lord is glorified by us: as again, how great a punishment to cause Him to be by our means blasphemed. And yet this very being glorified, He wisheth to be brought about for our sakes, since He doth not need it Himself. For what distance dost thou suppose to be between God and man? as great as that between men and worms? or as great as between Angels and worms? But when I have mentioned a distance even thus great, I have not at all expressed it: since to express its greatness is impossible. Would you, now, wish to have a great and marked reputation among worms? Surely not. If then thou that lovest glory, wouldest not wish for this, how should He Who is far removed from this passion, and so much farther above us, stand in need of glory from thee? Nevertheless, free from the want of it as He is, still He saith that He desireth it for thy sake. For if He endured for thy sake to become a slave, why wonder that He upon the same ground layeth claim to the other particulars also? For He counts nothing unworthy of Himself which may be conducive to our salvation. Since then we aware of this, let us shun sin altogether, because by reason of it He is blasphemed. For it says, "flee from sin, as from the face of a serpent: if thou comest too near unto it, it will bite thee" (Ecclus. xxi. 2): for it is not it that comes to us, but we that desert to it. God has so ordered things that the Devil should not prevail over us by compulsion (Gr. tyranny): since else none would have stood against his might. And on this account He set him a distant abode, as a kind of robber and tyrant. [1319] And unless he find a person unarmed and solitary for his assaults, he doth not venture to attack him. Except he see us travelling by the desert, [1320] he has not the courage to come near us. But the desert and place of the Devil is nothing else than sin. We then have need of the shield of faith, the helmet of salvation, the sword of the Spirit, not only that we may not get evil intreated, but that ever should he be minded to leap [1321] upon us, we may cut off his head. Need we have of continual prayer that he may be bruised under our feet, for he is shameless and full of hardihood, and this though he fights from beneath. But yet even so he gets the victory: and the reason is, that we are not earnestly set upon being above his blows. For he has not even the power to lift himself very high, but he trails along upon the ground. And of this the serpent is a type. But if God set him in that rank from the beginning, much more will He now. But if thou dost not know what fighting from beneath may be, I also will try to explain to thee the manner of this war. What then may this fighting "from beneath" (John viii. 23) be? It is standing upon the lower things of the world to buffet us, such as pleasure and riches and all the goods of this life. And for this reason, whoever he seeth flying toward heaven, first, he will not even be able to leap so far. Secondly, even if he should attempt he will speedily fall. For he hath no feet; be not afraid: he hath no wings; fear not. He trails upon the earth, and the things of the earth. Do thou then have naught in common with the earth, and thou wilt not need labor even. For he hath not any knowledge of open fight: but as a serpent he hideth him in the thorns, nestling evermore in the "deceitfulness of riches." (Matt. xiii. 22.) And if thou wert to cut away the thorns, he will easily be put to flight, being detected: [1322] and if thou knowest how to charm him with the inspired charms he will straightway be struck. For we have, we surely have, spiritual charms, even the Name of our Lord Jesus Christ and the might of the Cross. This charm will not only bring the serpent out of his lurking places, and cast him into the fire (Acts xxviii. 5), but even wounds it healeth. But if some that have said this Name have not been healed, it came of their own little faith, and was not owing to any weakness in what they said. For some did throng Jesus and press Him (Luke viii. 44, 45), and got no good therefrom. But the woman with an issue, without even touching His Body, but merely the hem of His garment, stanched a flux of blood of so long standing. (So St. Aug. Serm. LXII. iii. 4, p. 124 O.T.) This Name is fearful alike to devils, and to passions, and to diseases. In this then let us find a pleasure, herewith let us fortify ourselves. It was thus Paul waxed great, and yet he was of the like nature with ourselves, so the whole choir of the Disciples. But faith had made him a perfectly different person, and so much did it abound in them, that even their garments had great force. (Acts xix. 12.) What excuse then shall we deserve, if even the shadows and the garments of those men drave off death (Acts v. 15), but our very prayers do not so much as bring the passions down? What is the reason [1323] of it? Our temper is widely different. For what nature gives, is as much ours as theirs. For he was born and brought up just as we are, and dwelt upon the earth and breathed the air, as we do. But in other points he was far greater and better than we are, in zeal, in faith, and love. Let us then imitate him. Let us allow Christ to speak through us. He desireth it more than we do: and by reason of this, He prepared this instrument, and would not have it remain useless and idle, but wisheth to keep it ever in hand. Why then dost thou not make it serviceable for the Maker's hand, but lettest it become unstrung, and makest it relaxed through luxury, and unfittest the whole harp for His use, when thou oughtest to keep the members [1324] of it in full stretch, and well strung, and braced with spiritual salt. [1325] For if Christ see our soul thus attuned, He will send forth His sounds even by it. And when this taketh place, then shalt thou see Angels leaping for joy, (skirthontas) and Archangels too, and the Cherubim.
