Divine Mercy Shrine in the Philippines
(by day and night)
Our Lord Jesus said, "The soul that will go to Confession and receive Holy Communion shall obtain complete forgiveness of sins and punishment. On that day all the divine floodgates through which graces flow are opened. Let no soul fear to draw near to Me, even though its sins be as scarlet...Mankind will not have peace until it turns to the Fount of My Mercy."
- Saint Faustina, Diary, 699.
It is said that Our Lord's Divine Mercy Promise is even greater and more generous than a plenary indulgence!
