XIII. Why, then, in bestowing grace upon some, does he pass over others? Luke assigns a reason for the former, that they “were ordained to eternal life.” What conclusion, then, shall we draw respecting the latter, but that they are vessels of wrath to dishonour? Wherefore let us not hesitate to say with Augustine, “God could convert to good the will of the wicked, because he is omnipotent. It is evident that he could. Why, then, does he not? Because he would not. Why he would not, remains with himself.” For we ought not to aim at more wisdom than becomes us. That will be much better than adopting the evasion of Chrysostom, “that he draws those who are willing, and who stretch out their hands for his aid;” that the difference may not appear to consist in the decree of God, but wholly in the will of man. But an approach to him is so far from being a mere effort of man, that even pious persons, and such as fear God, still stand in need of the peculiar impulse of the Spirit. Lydia, the seller of purple, feared God, and yet it was necessary that her heart should be opened, to attend to, and profit by, the doctrine of Paul. This declaration is not made respecting a single female, but in order to teach us that every one’s advancement in piety is the secret work of the Spirit. It is a fact not to be doubted, that God sends his word to many whose blindness he determines shall be increased. For with what design does he direct so many commands to be delivered to Pharaoh? Was it from an expectation that his heart would be softened by repeated and frequent messages? Before he began, he knew and foretold the result. He commanded Moses to go and declare his will to Pharaoh, adding at the same time, “But I will harden his heart, that he shall not let the people go.”[572] So, when he calls forth Ezekiel, he apprizes him that he is sending him to a rebellious and obstinate people, that he may not be alarmed if they refuse to hear him.[573] So Jeremiah foretells that his word will be like fire, to scatter and destroy the people like stubble.[574] But the prophecy of Isaiah furnishes a still stronger confirmation; for this is his mission from the Lord: “Go and tell this people, Hear ye, indeed, but understand not, and see ye, indeed, but perceive not. Make the heart of this people fat, and make their ears heavy, and shut their eyes; lest they see with their eyes, and hear with their ears, and understand with their heart, and convert, and be healed.”[575] Observe, he directs his voice to them, but it is that they may become more deaf; he kindles a light, but it is that they may be made more blind; he publishes his doctrine, but it is that they may be more besotted; he applies a remedy, but it is that they may not be healed. John, citing this prophecy, declares that the Jews could not believe, because this curse of God was upon them.[576] Nor can it be disputed, that to such persons as God determines not to enlighten, he
