20. And the Lord said, I have pardoned, according to thy word. God signifies that tie pardons for His servant Moses’ sake, and makes, as it were, a present to him of those whom He had already devoted to destruction. Hence we gather how much the entreaties of the pious avail with God: as He is said, in Psalms 145:19, to “fulfil the desire of them that fear him.” He would, indeed, have done of His own accord what He granted to Moses; but, in order that we may be more earnest in prayer, the use and advantage of prayers is commended, when God declares that He will not only comply with our requests, but even obey them.
But how is it consistent for Him to declare that He had spared those, upon whom He had determined to inflict the most extreme punishment, and whom He deprived of their promised inheritance? I reply that the pardon in question was not granted to the individuals, but to their race and name. For the opinion of some is unnatural, who think that they were released from the penalty of eternal death, and thence that God was propitiated towards them, because He was contented with their temporal punishment. I do not doubt, then, but that Moses was so far heard, as that the seed of Abraham should not be destroyed, and the covenant of God should not fail For He so dispensed the pardon as to preserve their posterity uninjured, whilst He inflicted on the unbelievers themselves the reward of their rebellion. Thus the conditions of the pardon were of no advantage to the impious rebels, though they opened a way for the faithful fulfillment of His promise.
