John 3:19

“And this is the condemnation, etc.] Of him that believes not in Christ; that is, this is the matter and cause of his condemnation, and by which it is aggravated, and appears to be just: that light is come into the world: by which is meant, not natural or corporeal light; though natural darkness is, by some, preferred to this, being more convenient for their evil works; as by thieves, murderers, and adulterers: nor is the light of nature designed, with which every man is enlightened that comes into the world; which, though but a dim light, might be of more use, and service, than it is; and is often rejected, and rebelled against, by wicked men, and which will be the condemnation of the…”

Those who refuse to believe live in darkness (cp. 13:30) and stumble because they cannot see (11:10). In the end, however, their sins will be exposed (5:28-30; Rev 20:11-15).”
