Here are some Morning Offering formulae. You can, of course, compose your own. Remember, too, that those who say Morning Prayer from the Liturgy of the Hours offer their day to the Lord in that way, too. A focused, deliberate and loving offering of the day to the Lord, though, is always a good thing to do.
O Jesus, through the Immaculate Heart of Mary, I offer you my prayers, works, joys and sufferings of this day in union with the Holy Sacrifice of the Mass throughout the world. I offer them for all the intentions of your Sacred Heart: the salvation of souls, the reparation for sin, and the reunion of all Christians. I offer them for the intentions of our bishops and of all Apostles of Prayer, and in particular for those recommended by our Holy Father this month.
My God, I adore You, and I love You with all my heart. I thank you for having created me, made me a Christian, and preserved me this night. I offer You the actions of this day. Grant that all of them may be in accordance with Your holy Will and for Your greater glory. Protect me from sin and from all evil. Let Your grace be always with me and with all my dear ones. Amen.
Lord Jesus Christ, in union with that divine intention with which You offered to God Your praises on earth through Your most Sacred Heart, and now offer them in the Sacrament of the Eucharist everywhere even to the end of time, I most gladly offer You throughout this entire day, all my thoughts and intentions, all my affections and desires, all my words and deeds, in imitation of the most holy heart of the Blessed Virgin Mary Immaculate. Amen.
Into Thy hands, O God, we commend ourselves this day, and all those who are dear to us. Let the gift of thy wonderful presence be with us even to the end of the day. Grant that we never lose sight of Thee all the day long, but rather praise and beseech Thee, that our thanks may come to thee again at its close. Amen
Lord Jesus, I unite myself to Your perpetual, unceasing, universal Sacrifice. I offer myself to You every day of my life and every moment of every day, according to Your most holy and adorable Will. Since You have been the Victim of my salvation, I wish to be the victim of Your love. Accept my desire, take my offering, and graciously hear my prayer. Let me live for love of You; let me die for love of You; let my last heartbeat be an act of perfect love. (St. Therese of Lisieux)
