1. “But,” say they, “God hardened the heart of Pharaoh and of his servants.” Those, then, who allege such difficulties, do not read in the Gospel that passage where the Lord replied to the disciples, when they asked Him, “Why speakest Thou unto them in parables?”—“Because it is given unto you to know the mystery of the kingdom of heaven; but to them I speak in parables, that seeing they may not see, and hearing they may not hear, understanding they may not understand; in order that the prophecy of Isaiah regarding them may be fulfilled, saying, Make the heart of this people gross and make their ears dull, and blind their eyes. But blessed are your eyes, which see the things that ye see; and your ears, which hear what ye do hear.” For one and the same God [that blesses others] inflicts blindness upon those who do not believe, but who set Him at naught; just as the sun, which is a creature of His, [acts with regard] to those who, by reason of any weakness of the eyes cannot behold his light; but to those who believe in Him and follow Him, He grants a fuller and greater illumination of mind. In accordance with this word, therefore, does the apostle say, in the Second [Epistle] to the Corinthians: “In whom the this world hath blinded the minds of them that believe not, lest the light of the glorious Gospel of Christ should shine [unto them].” And again, in that to the Romans: “And as they did not think fit to have God in their knowledge, God gave them up to a reprobate mind, to do those things that are not convenient.” Speaking of antichrist, too, he says clearly in the Second to the Thessalonians: “And for this cause God shall send them the working of error, that they should believe a lie; that they all might be judged who believed not the truth, but consented to iniquity.”
