This Morning Offering was composed by St Thérèse of Lisieux and can be found in Thérèse of Lisieux: Prayers & Devotions.

O my God! I offer you all my actions of this day for the intentions and for the glory of the Sacred Heart of Jesus. I desire to sanctify every beat of my heart, my every thought, my simplest works, by uniting them to its infinite merits; and I wish to make reparation for my sins by casting them into the furnace of its merciful love. O my God! I ask of you for myself and for those whom I hold dear the grace to fulfil perfectly your holy will, to accept for love of you the joys and sorrows of this passing life, so that we may one day be united together in Heaven for all eternity. Amen.
