St. Augustine has a famous quote that says that God is closer to me than I am to myself (cf. Confessions, III, 6, 11). From here he formulates the invitation: "Do not go outside yourself, come back into yourself: truth dwells in the heart of man" (True Religion, 39, 72). This is another aspect that we risk losing in the noisy and distracted world in which we live: the ability to stop and take a deep look within ourselves and read that thirst for the infinite that we carry within, pushing us to go further and towards that Someone who can satisfy it. The Catechism of the Catholic Church states: "with his openness to truth and beauty, his sense of moral goodness, his freedom and the voice of his conscience, with his longings for the infinite and for happiness, man questions himself about God's existence" (n. 33).
