Chapter 29.—God is Able to Convert Opposing Wills, and to Take Away from the Heart Its Hardness.

Now if faith is simply of free will, and is not given by God, why do we pray for those who will not believe, that they may believe? This it would be absolutely useless to do, unless we believe, with perfect propriety, that Almighty God is able to turn to belief wills that are perverse and opposed to faith. Man’s free will is addressed when it is said, “Today, if ye will hear His voice, harden not your hearts.”189    Ps. xcv. 7, 8. But if God were not able to remove from the human heart even its obstinacy and hardness, He would not say, through the prophet, “I will take from them their heart of stone, and will give them a heart of flesh.”190    Ezek. xi. 19. That all this was foretold in reference to the New Testament is shown clearly enough by the apostle when he says, “Ye are our epistle, . . . written not with ink, but with the Spirit of the living God; not in tables of stone, but in fleshly tables of the heart.”191    2 Cor. iii. 2, 3. We must not, of course, suppose that such a phrase as this is used as if those might live in a fleshly192    [That is, “carnally,” the Latin phrase in 2 Cor. iii. 3 being capable alike of the literal and metaphorical sense of “fleshly.”—W.] way who ought to live spiritually; but inasmuch as a stone has no feeling, with which man’s hard heart is compared, what was there left Him to compare man’s intelligent heart with but the flesh, which possesses feeling? For this is what is said by the prophet Ezekiel: “I will give them another heart, and I will put a new spirit within you; and I will take the stony heart out of their flesh, and will give them a heart of flesh; that they may walk in my statutes, and keep mine ordinances, and do them: and they shall be my people, and I will be their God, saith the Lord.”193    Ezek. xi. 19, 20. Now can we possibly, without extreme absurdity, maintain that there previously existed in any man the good merit of a good will, to entitle him to the removal of his stony heart, when all the while this very heart of stone signifies nothing else than a will of the hardest kind and such as is absolutely inflexible against God? For where a good will precedes, there is, of course, no longer a heart of stone.

29. Nam si fides liberi est tantummodo arbitrii, nec datur a Deo, propter quid pro eis qui nolunt credere, oramus ut credant? Quod prorsus faceremus inaniter, nisi rectissime crederemus, etiam perversas et fidei contrarias voluntates omnipotentem Deum ad credendum posse convertere. Liberum quidem hominis arbitrium pulsatur, ubi dicitur: Hodie si vocem ejus audieritis, nolite obdurare corda vestra (Psal. XCIV, 8). Sed nisi posset Deus etiam duritiam cordis auferre, non diceret per prophetam: Auferam ab eis cor lapideum, et dabo eis cor carneum. Quod de novo Testamento fuisse praedictum, satis Apostolus ostendit, ubi ait: Epistola nostra vos estis, scripta non atramento, sed spiritu Dei vivi; non in tabulis lapideis, sed in tabulis cordis carnalibus (II Cor. III, 2). Quod non ideo dictum putemus, ut carnaliter vivant qui debent spiritualiter vivere: sed, quia lapis sine sensu est, cui comparatum est cor durum, cui nisi carni sentienti cor intelligens debuit comparari? Sic enim hoc dicitur per Ezechielem prophetam: Et dabo eis, inquit, cor aliud, et spiritum novum dabo eis; et evellam cor lapideum de carne eorum, et dabo eis cor carneum, ut in praeceptis meis ambulent, et justificationes meas observent, et faciant eas: et erunt mihi in populum, et ego ero eis in Deum, dicit Dominus (Ezech. XI, 19, 20). Numquid ergo possumus nisi absurdissime dicere, bonum meritum bonae voluntatis in homine praecessisse, ut evelleretur ab eo cor lapideum: quandoquidem ipsum cor lapideum non significat nisi durissimam voluntatem et adversus Deum omnino inflexibilem? Ubi enim praecedit bona voluntas, jam non est utique cor lapideum.
