In fact, by these tropes matters will come to this:—you may say, that God had   mercy upon the children of Israel when He sent them into Assyria and to Babylon; because,   He there punished the sinners, and there invited them, by afflictions, to repentance: and   that, on the other hand, when He delivered them and brought them back, He had not then   mercy upon them, but hardened them; that is, by His long-suffering and mercy He gave them   an occasion of becoming hardened. And also, God's sending the Saviour Christ into the   world, will not be said to be the mercy, but the hardening of God; because, by this mercy,   He gave men an occasion of hardening themselves. On the other hand, His destroying   Jerusalem, and scattering the Jews even unto this day, is His having mercy on them;   because, He punishes the sinners and invites them to repentance. Moreover, His carrying   the saints away into heaven at the day of judgment, will not be in mercy, but in   hardening; because, by His long-suffering, He will give them an occasion of abusing it.   But His thrusting the wicked down to hell, will be His mercy; because, He punishes the   sinners.—Who, I pray you, ever heard of such examples of the mercy and wrath of God   as these?
 
   And be it so, that good men are made better both by the long-suffering and by the   severity of God; yet, when we are speaking of the good and the bad promiscuously, these   tropes, by an utter perversion of the common manner of speaking, will make, out of the   mercy of God His wrath, and His wrath out of His mercy; seeing that, they call it the   wrath of God when He does good, and His mercy when He afflicts.
 
   Moreover, if God be said then to harden, when He does good and endures with   long-suffering, and then to have mercy when He afflicts and punishes, why is He more   particularly said to harden Pharaoh than to harden the children of Israel, or than the   whole world? Did He not do good to the children of Israel? Does He not do good to the   whole world? Does He not bear with the wicked? Does He not rain upon the evil and upon the   good? Why is He rather said to have mercy upon the children of Israel than upon Pharaoh?   Did He not afflict the children of Israel in Egypt, and in the desert?—And be it so,   that some abuse, and some rightly use, the goodness and the wrath of God; yet, according   to your definition, to harden, is the same as, to indulge the wicked by long-suffering and   goodness; and to have mercy, is, not to indulge, but to visit and punish. Therefore, with   reference to God, He, by His continual goodness, does nothing but harden; and by His   perpetual punishment, does nothing but shew mercy.
 
   Sect. 79.—B[SIZE=-1]UT[/SIZE] this is the most   excellent statement of all—'that God is said to harden, when He indulges sinners by   long-suffering; but to have mercy upon them, when He visits and afflicts, and thus, by   severity, invites to repentance.'— 
   What, I ask, did God leave undone in afflicting, punishing, and calling Pharaoh to   repentance? Are there not, in His dealings with him, ten plagues recorded? If, therefore,   your definition stand good, that shewing mercy, is punishing and calling the sinner   immediately, God certainly had mercy upon Pharaoh! Why then does not God say, I will have   mercy upon Pharaoh? Whereas He saith, "I will harden the heart of Pharaoh." For,   in the very act of having mercy upon him, that is, (as you say) afflicting and punishing   him, He saith, "I will harden" him; that is, as you say, I will bear with him   and do him good. What can be heard of more enormous! Where are now your tropes? Where are   your Origens? Where are your Jeromes? Where are all your most approved doctors whom one   poor creature, Luther, daringly contradicts?—But at this rate the flesh must unawares   impel the man to talk, who trifles with the words of God, and believes not their solemn   importance!
 
   The text of Moses itself, therefore, incontrovertibly proves, that here, these tropes   are mere inventions and things of nought, and that by those words, "I will harden the   heart of Pharaoh," something else is signified far different from, and of greater   importance than, doing good, or affliction and punishment; because, we cannot deny, that   both were tried upon Pharaoh with the greatest care and concern. For what wrath and   punishment could be more instant, than his being stricken by so many wonders and with so   many plagues, that, as Moses himself testifies, the like had never been? Nay, even Pharaoh   himself, repenting, was moved by them more than once; but he was not effectually moved,   nor did he persevere. And what long-suffering or goodness of God could be greater, than   His taking away the plagues so easily, hardening his sin so often, so often bringing back   the good, and so often taking away the evil? Yet neither is of any avail, He still saith,   "I will harden the heart of Pharaoh!" You see, therefore, that even if your hardening   and mercy, that is, your glosses and tropes, be granted to the greatest extent, as   supported by use and by example, and as seen in the case of Pharaoh, there is yet a   hardening that still remains; and that the hardening of which Moses speaks must, of   necessity, be one, and that of which you dream, another.
