"Whenever you hear the clock strike the third hour, immerse yourself completely in my mercy, adoring it and glorifying it, invoke its omnipotence for the whole world, and particularly for poor sinners; for at that moment mercy was opened wide for every should. In this hour you can obtain everything you ask for yourself and for others. It was the hour of grace for the whole world; mercy triumphed over justice." (Diary of St. Faustina Kowalska 1572)
