Preparatory prayer for every day
By the sign of the holy cross, of our enemies, liberate us Lord our God
My Lord, Jesus Christ, God and true Man, Creator, Father and Redeemer of mine, because you are who you are and because I love you above all things, it is with all my heart that I have offended you; I firmly propose never to sin again, to turn away from all occasions of offenses, to confess myself and to fulfill the penance imposed on me.
I offer, Lord, my life, works, in satisfaction of all my sins, and, as I beg, I trust in your infinite kindness and mercy, that you will forgive them, for the merits of your precious blood, passion and death, and you will give me grace to amend me, and to persevere in your holy love and service, until the end of my life.
Amen.
V . Blessed and praised be the sweetest names of Jesus, Mary and Joseph.
R . Amen.
We turn to you, kind Patriarch, and with all the fervor of our afflicted heart we ask you, from the throne of glory in which they placed your virtues and merits, listen to our prayers and have mercy on us.
We humbly confess that our tribulations are sorrow of our sins; therefore with heartfelt pain, we ask God for forgiveness of all of them. Reach us, loving Saint Joseph, and for the love you professed to your Jesus and Mary and for the authority that you exercised over them here on earth, intercede now for us in heaven listening to our petitions and presenting them yourself to your immaculate Bride and your Divine Son so that they may be favorably dispatched, for the greater glory of God and sanctification of our souls. Amen.
Remember, oh chaste spouse of the Virgin Mary and kind protector of my Saint Joseph, that has never been heard that any invoked your protection and implored your help without having been consoled. Full, then, of confidence in your power, since you exercised with Jesus the office of Father, I come to your presence and I commend myself to you with all fervor. Do not dismiss my supplications, rather, welcome them and deserve to access them piously. Amen.
