Neither are we to suppose that because sin shall have no power to delight them, free will must be withdrawn. It will, on the contrary, be all the more truly free, because set free from delight in sinning to take unfailing delight in not sinning. For the first freedom of will which man received when he was created upright consisted in an ability not to sin, but also in an ability to sin; whereas this last freedom of will shall be superior, inasmuch as it shall not be able to sin. This, indeed, shall not be a natural ability, but the gift of God. For it is one thing to be God, another thing to be a partaker of God. God by nature cannot sin, but the partaker of God receives this inability from God. And in this divine gift there was to be observed this gradation, that man should first receive a free will by which he was able not to sin, and at last a free will by which he was not able to sin,—the former being adapted to the acquiring of merit, the latter to the enjoying of the reward. But the nature thus constituted, having sinned when it had the ability to do so, it is by a more abundant grace that it is delivered so as to reach that freedom in which it cannot sin. For as the first immortality which Adam lost by sinning consisted in his being able not to die, while the last shall consist in his not being able to die; so the first free will consisted in his being able not to sin, the last in his not being able to sin. And thus piety and justice shall be as indefeasible as happiness. For certainly by sinning we lost both piety and happiness; but when we lost happiness, we did not lose the love of it. Are we to say that God Himself is not free because He cannot sin? In that city, then, there shall be free will, one in all the citizens, and indivisible in each, delivered from all ill, Filled with all good, enjoying indefeasibly the delights of eternal joys, oblivious of sins, oblivious of sufferings, and yet not so oblivious of its deliverance as to be ungrateful to its Deliverer.
