Jesus said, “This is the judgment, that the Light has come into the world, and men loved the darkness rather than the Light, for their deeds were evil. For everyone who does evil hates the Light, and does not come to the Light for fear that his deeds will be exposed” (John 3:19-20).
To which an unbeliever might say, “I do love sin and it doesn’t matter. I’m not afraid…” Unfortunately, this is a response of self-delusion and self-deception. As James Janeway noted,
It is no unusual thing for a vile unsanctified sinner to leap with a mad confidence into eternity. [Quoted in A Golden Treasury of Puritan Devotion]
He may say he is not afraid, but his reticence to repent is indicative of a fear of losing his “right” to sin and of losing his “right” to worship himself as the god of his own world. It is madness, indeed. An eternal and exceedingly sorrowful madness.
