Nicodemus answered him, "How can these things be?"
(2.) Read also the doom of those that would not so much as know him, John 3:19. Many inquisitive people had knowledge of Christ and his doctrine and miracles, but they were prejudiced against him, and would not believe in him, while the generality were sottishly careless and stupid, and would not know him. And this is the condemnation, the sin that ruined them, that light is come into the world, and they loved darkness rather. Now here observe, [1.] That the gospel is light, and, when the gospel came, light came into the world, Light is self-evidencing, so is the gospel; it proves its own divine origin. Light is discovering, and truly the light is sweet, and rejoices the heart. It is a light shining in a dark place, and a dark place indeed the world would be without it. It is come into all the world (Colossians 1:16), and not confined to one corner of it, as the Old-Testament light was. [2.] It is the unspeakable folly of the most of men that they loved darkness rather than light, rather than this light. The Jews loved the dark shadows of their law, and the instructions of their blind guides, rather than the doctrine of Christ. The Gentiles loved their superstitious services of an unknown God, whom they ignorantly worshipped, rather than the reasonable service which the gospel enjoins. Sinners that were wedded to their lusts loved their ignorance and mistakes, which supported them in their sins, rather than the truths of Christ, which would have parted them from their sins. Man's apostasy began in an affectation of forbidden knowledge, but is kept up by an affectation of forbidden ignorance. Wretched man is in love with his sickness, in love with his slavery, and will not be made free, will not be made whole. [3.] The true reason why men love darkness rather than light is because their deeds are evil. They love darkness because they think it is an excuse for their evil deeds, and they hate the light because it robs them of the good opinion they had of themselves, by showing them their sinfulness and misery. Their case is sad, and, because they are resolved that they will not mend it, they are resolved that they will not see it. [4.] Wilful ignorance is so far from excusing sin that it will be found, at the great day, to aggravate the condemnation: This is the condemnation, this is what ruins souls, that they shut their eyes against the light, and will not so much as admit a parley with Christ and his gospel; they set God so much at defiance that they desire not the knowledge of his ways, Job 21:14. We must account in the judgment, not only for the knowledge we had, and used not, but for the knowledge we might have had, and would not; not only for the knowledge we sinned against, but for the knowledge we sinned away. For the further illustration of this he shows (John 3:20-21) that according as men's hearts and lives are good or bad, so they stand affected to the light Christ has brought into the world.
