Jesus said, "I desire that you know more profoundly the love that burns in My Heart for souls, and you will understand this when you meditate upon My Passion...When you say this prayer, with a contrite heart and with faith on behalf of some sinner, I will give him the grace of conversion. This is the prayer:

O Blood and Water, which gushed forth from the Heart of Jesus, as a fount of mercy for us, I trust in You."    WORDS OF JESUS TO ST. FAUSTINA   (Diary 186-187)
