If you learn from Saint Thérèse to depend on God alone and serve him with a wholly pure and detached heart, then you can join with your whole soul in singing the jubilant song of the holy Virgin, “My soul proclaims the greatness of the Lord, and my spirit rejoices in God my Savior. For he has done great things for me, and holy is his name.” And like little St. Thérèse you will be able to say at the end, “I do not regret that I have given myself to love.”
