Thanksgiving After Confession

"What man among you having a hundred sheep and losing one of them would not leave the ninety-nine in the desert and go after the lost one until he finds it? And when he does find it, he sets it on his shoulders with great joy and, upon his arrival home, he calls together his friends and neighbors and says to them, 'Rejoice with me because I have found my lost sheep.' I tell you, in just the same way there will be more joy in heaven over one sinner who repents than over ninety-nine righteous people who have no need of repentance." (Luke 15: 4-7)

How great are Thy mercies towards me, O Lord, in having pardoned my
sins after so many relapses! I now know better than ever the evil of
having offended a God of infinite goodness. Thou mightest have
condemned me a thousand times, and case me into hell, as Thy justice
demanded, but Thou hast had compassion on me.

Ah, blessed forever be Thy unspeakable and infinite mercy! How can I
thank Thee worthily, O Lord? Ye heavens and earth assist me in
offering thanksgiving to my God.

O Lord, I unite myself with every creature on earth and in heaven,
exclaiming with them, "Salvation to our God, Who sitteth upon the
throne, and to the Lamb. Benediction, and glory, and wisdom, and
thanksgiving, and honor, and power, and strength to our God, for ever
and ever." Amen

Mary, my most tender Mother, lend me thy heart, that I may love thy
divine Son. Ye blessed Angels, thank God in my place. All ye Saints,
come to my aid.
