Irenaeus — on Rom 1:28 (Against Heresies Book IV)

“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 god of 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."”
