John 3:19

And this is the condemnation,.... 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 Heathen world: but rather the light of divine revelation, both in the law of God, and Gospel of Christ; especially the latter is here intended; and which, though so great a favour to fallen men, is despised, and denied by the sons of darkness: though it may be best of all to understand it of Christ himself, the light of the world, and who is come a light into it; see Joh 8:12, who may be called "light", because he has set revelation in its clearest and fullest light; he has declared the whole mind, and will of God concerning the affair of divine worship, and the business of salvation: grace, and truth, are come by him; the doctrines of grace, and the truths of the Gospel, are most clearly brought to light by him; the types, and shadows of the law are removed; and the promises, and the prophecies of the Old Testament, are most largely expounded by him, and most perfectly fulfilled in him: and besides; he is the author and giver of the light of grace, by which men see themselves to be what they are, lost and undone sinners; and see him to be the only able, willing, suitable, sufficient, and complete Saviour: and he it is that now gives the saints the glimpse of glory they have, and will be the light of the new Jerusalem, and the everlasting light of his people hereafter.
