"Leo, listen carefully to me. Don't be so preoccupied with the purity of your heart. Turn and look at Jesus. Admire him. Rejoice that he is what he is -- your Brother, your Friend, your Lord and Savior. That, little brother, is what it means to be pure of heart. And once you've turned to Jesus, don't turn back and look at yourself. Don't wonder where you stand with him."
