Eternal Father, I humbly adore Thee, and thank Thee for having created me, and for having redeemed me through Jesus Christ. I thank Thee most sincerely for having made me a Christian, by giving me the true faith, and by adopting me as Thy son / daughter, in the sacrament of baptism.
I thank Thee for having, after the numberless sins I had committed, waited for my repentance, and for having pardoned (as I humbly hope) all the offences which I have offered to Thee, and for which I am now sincerely sorry, because they have been displeasing to Thee, Who art Infinite Goodness.
I thank Thee for having preserved me from so many relapses, of which I would have been guilty if Thou hadst not protected me. But my enemies still continue, and will continue till death, to combat against me, and to endeavor to make me their slave.
If Thou dost not constantly guard and succor me with Thy aid, I, a miserable creature, shall return to sin, and shall certainly lose Thy grace. I beseech Thee, then, for the love of Jesus Christ, to grant me holy perseverance unto death.
Jesus, Thy Son, has promised that Thou wilt grant whatsoever we ask in His Name. Through the merits, then, of Jesus Christ, I beg, for myself and for all the just, the grace never again to be separated from Thy love, but to love Thee forever, in time and eternity. Mary, Mother of God, pray to Jesus for me. Amen.
