Catholic Prayer: Prayer of Dedication by St. Francis de Sales
This beautiful prayer from Treatise on the Love of God by St. Francis de Sales is a prayer of giving oneself totally to God, of wanting to love Him above all things.
Lord, I am yours, and I must belong to no one but you. My soul is yours, and must live only by you. My will is yours, and must love only for you. I must love you as my first cause, since I am from you. I must love you as my end and rest, since I am for you. I must love you more than my own being, since my being subsists by you. I must love you more than myself, since I am all yours and all in you. Amen.
