The Morning Offering is a simple, traditional prayer with several variations. This one is my favorite.
“Most Sacred Heart of Jesus and Immaculate Heart of Mary, I offer myself and my family to you [add names of all family members]. To show to you our devotion this day, we offer you our eyes, our ears, our hearts our minds, our entire being, without reserve. Therefore dear Mother and sweet Jesus, as we are your own, guard us and keep us always as your property and possession.
