Deuteronomy 9:5

5.Not for thy righteousness. First of all, he would have the punishment inflicted upon these nations awaken the Israelites to fear, and thus that they should attribute nothing to themselves; because it was God’s design not to reward their merits, but to shew the severity of His judgment. Secondly, he confirms this by two arguments; viz., because God thus had performed what He promised Abraham; (which promise, as has been already seen, was founded on mere grace;) and, again, because the people itself was naturally perverse and rebellious. Hence, it sufficiently appears that there was no room for merits, since by them God’s covenant would have been nullified, nor, if there were, could any such be found in so depraved and contumacious a nation. And besides, God had made His covenant with Abraham almost four centuries before they were born. Hence it follows that this benefit proceeded from some other source. But he still further represses their pride, by reproaching them with being “stiff-necked;” for it would have been too absurd to imagine that God, whom they had not ceased to provoke with their sins, was under obligation to them, as if they had duly discharged their duty. This metaphor is taken from oxen, which are useless until they are accustomed to bend their necks; it is then the same as saying that they were not only unsubmissive, but that in their obstinacy they shook off the yoke. By his impressing on them, for the third time, that the Israelites had not deserved the land by their righteousness, we learn that nothing is more difficult than for men to strip themselves of their blind arrogance, whereby they detract some portion of the praise from God’s mercies. Now, if in regard to an earthly inheritance God so greatly exalts His mercy, what must we think of the heavenly inheritance? (250) He would have it attributed to Himself alone, that the children of Israel possess the land of Canaan; how much less, then, will He tolerate the obtrusion of men’s merits in order to the acquisition of heaven? Nor is there anything in the pretense of the Papists that they attribute the first place to God’s bounty; because He claims altogether for Himself what they would share with Him. But if any object that this was only said to His ancient people, I reply, that we are no better than they. Let each retire into himself, (251) and he will not excuse the hardness of his neck. But they who are regenerated by God’s Spirit, know that they are not naturally formed unto obedience; and thus that it is only mercy which makes them to differ from the worst of men.
