John Calvin - Two methods in which God may blind and harden the reprobate

Ancient writers sometimes manifest a superstitious dread of making a simple confession of the truth in this matter, from a fear of furnishing impiety with a handle for speaking irreverently of the works of God. While I embrace such soberness with all my heart, I cannot see the least danger in simply holding what Scripture delivers. when Augustine was not always free from this superstition, as when he says, that blinding and hardening have respect not to the operation of God, but to prescience, (August. de Predestina. et Gratia.) But this subtlety is repudiated by many passages of Scriptures which clearly show that the divine interference amounts to something more than prescience. And Augustine himself, in his book against Julian, contends at length that sins are manifestations not merely of divine permission or patience, but also of divine power, that thus former sins may be punished. In like manner, what is said of permission is too weak to stand. God is very often said to blind and harden the reprobate, to turn their hearts, to incline and impel them, as I have elsewhere fully explained, (Book 1 c. 18) The extent of this agency can never be explained by having recourse to prescience or permission. We, therefore, hold that there are two methods in which God may so act. When his light is taken away, nothing remains but blindness and darkness: when his Spirit is taken away, our hearts become hard as stones: when his guidance is withdrawn, we immediately turn from the right path: and hence he is properly said to incline, harden, and blind those whom he deprives of the faculty of seeing, obeying, and rightly executing. The second method, which comes much nearer to the exact meaning of the words, is when executing his judgements by Satan as the minister of his anger, God both directs men's counsels, and excites their wills, and regulates their efforts as he pleases. Thus when Moses relates that Simon, king of the Amorites, did not give the Israelites a passage, because the Lord "had hardened his spirit, and made his heart obstinate," he immediately adds the purpose which God had in view, viz., that he might deliver him into their hand, (Deut. 2: 30.) As God had resolved to destroy him, the hardening of his heart was the divine preparation for his ruin.
