Proverbs 4:18

But the path of the just is as the shining light— The presence of the just enlightens, instructs, edifies, rejoices: they carry light into every place by their example, and by their instructions. And they grow more and more in knowledge, grace, and consolation, until all be perfected and swallowed up in glory. The wicked, on the contrary, are always in darkness, Proverbs 4:19. The former are the children of light of whom the gospel speaks; the other are the children of darkness, who know not against what they are about to stumble. They commit sin without scruple; they deliver themselves up to it without remorse; they fall without grief, and they continue in it without repentance.
