John Calvin Commentary John 3:20

"For every one that doeth evil hateth the light, and cometh not to the light, lest his works should be reproved." — John 3:20 (ASV)

For whosoever doeth what is evil. The meaning is, that the light is hateful to them for no other reason than because they are wicked and desire to conceal their sins, as much as they can. Hence it follows that, by rejecting the remedy, they may be said purposely to cherish the ground of their condemnation. We are greatly mistaken, therefore, if we suppose that those who are enraged against the Gospel are motivated by godly zeal, when, on the contrary, they abhor and shun the light, that they may more freely flatter themselves in darkness.
