So it is with human emotions and worldly pleasures versus Divine Love. Sin on it's own seems good when it is surrounded only by more of itself away from God. But when the sin is held up to Christ the Light of the World, the light of sin is so insignificant that it cannot even be seen-so radically more intense is the light of Divine Love over the sin of the world. It is a difference that can only be appreciated when you have seen both. Show someone the glory of Divine Love and once they have considered it seriously, they will see themselves as unworthy because they degraded themselves in such horrible sins. You don't even need to mention someone's sins to get them to repent.
"And the light of the moon shall be as the light of the sun, and the light of the sun shall be sevenfold, as the light of seven days: in the day when the Lord shall bind up the wound of his people, and shall heal the stroke of their wound."-Isaias 30:26
