Traditional Prayer of Reparation from the Irish

Most sacred heart of Jesus, have mercy on me.
O God, forgive me for all the sins of my life;
The sins of my youth and the sins of my age,
The sins of my body and the sins of my soul,
The sins I have confessed and the sins I have forgotten,
The sins against others in thought, word, and deed,
My sins of omission.
O, my God, I am sorry for all my sins, because you are so good;
And I will not sin again with the help of God.
God be merciful to me, a sinner.
Divine heart of Jesus, convert sinners, save the dying,
Deliver the holy souls in purgatory.
