John Chrysostom — as excerpted in the Catena Aurea on John 3:19-21

“(Hom. xxviii. 2) Then because it seemed incredible that man should prefer light to darkness, he gives the reason of the infatuation, viz. that their deeds were evil. And indeed had He come to Judgment, there had been some reason for not receiving Him; for he who is conscious of his crimes, naturally avoids the judge. But criminals are glad to meet one who brings them pardon. And therefore it might have been expected that men conscious of their sins would have gone to meet Christ, as many indeed did; for the publicans and sinners came and sat down with Jesus. But the greater part being too cowardly to undergo the toils of virtue for righteousness’ sake, persisted in their wickedness to the last; of whom our Lord says, Every one that doeth evil, hateth the light. He speaks of those who choose to remain in their wickedness.”
