St. Margaret Mary
“You will do nothing unless you ask Him for the help of His grace. And this I am sure He will give you to the measure in which you trust Him. Moreover, we must live the life of love. By our humble submission and complete self-effacement it will unite us with Him and make us altogether like Him in His life of sacrifice, abandonment, and love in the Blessed Sacrament.”
