Our Lord tells us there is more joy in heaven over one sinner who repents than over ninety nine others who have no need of repentance. It may seem strange to us to imagine the existence of such a joy, especially in regard to ourselves. Perhaps very few of us allow ourselves to weep true tears of repentance, to experience true sorrow for our sins, and so never come to know that heavenly joy. Tears that emerge from eyes that gaze upon Christ are the prelude to the loving embrace of the Heavenly Bridegroom.
If there is one thing the devil would want to prevent it is this movement from sorrow to joy, from repentance to intimacy. He would keep us in the despair of our own wretchedness, despondent through lack of hope in forgiveness or convince us that our sins are of no account - such that our repentance produces no tears, internal or external. In both cases, we see only the light of salvation fade and the heart grow cold.
