These prayers were given to the 3 children by the Angel of Fatima. They are to be prayed often, for the conversion of sinners:
O Most Holy Trinity, I adore Thee!
My God, my God, I love Thee in the Most Blessed Sacrament!
————————————
My God, I believe, I adore, I trust, and I love Thee. I beg pardon for those who do not believe, do not adore, do not trust, and do not love Thee.(repeat three times)
————————————
Most Holy Trinity, Father, Son, and Holy Spirit,
I adore you profoundly.
I offer you the most Precious Body, Blood, Soul, and Divinity of Jesus Christ,
present in all the tablernacles of the world,
in reparation for the outrages, sacrileges, and indifference by which He is offended.
By the infinite merits of the Sacred Heart of Jesus,
in union with the Immaculate Heart of Mary,
I beg of you the conversion of poor sinners.
