My God, I am yours for time and eternity. Teach me to cast myself entirely into the arms of your loving providence, with the most lively, unlimited confidence in your compassionate, tender pity. Grant me, O most merciful Redeemer, that whatever you ordain or permit may be acceptable to me. Take from my heart all painful anxiety; suffer nothing to sadden me but sin, nothing to delight me but the hope of coming to the possession of you, my God and my all, in your everlasting kingdom.
