O my Jesus, forgive us our sins,
And save us from the fires of hell.
Lead all souls to heaven,
especially those most in need of your mercy.
This prayer is reported to be requested by the Blessed Virgin Mary when she appeared to children at Fatima.
It is predominantly a Catholic prayer, and although the use of modern English is common, some parishes in the United States still use the archaic English: “most in need of thy mercy.”
