The first request made by Our Lady of Fatima is to sanctify our daily duties. Here is the official My Morning Offering prayer:
O my God, in union with the Immaculate Heart of Mary, I offer Thee the Precious Blood of Jesus from all the altars throughout the world, joining with it the offering of my every thought, word, and action of this day.
O my Jesus, I desire today to gain every indulgence and merit I can, and I offer them together with myself to Mary Immaculate ~ that she may best apply them to the interests of Thy most Sacred Heart. Precious Blood of Jesus, save us! Immaculate Heart of Mary, pray for us! Sacred Heart of Jesus, have mercy on us!
If we are prepared to offer God our every thought, word, and action of the day, we'd better make sure that every thought, word, and action of ours is good and pure. I see making this morning offering an excellent way to keep us holy.
