Surely Divine Providence in his Marvellous Plans sometimes uses us miserable little twigs to do good and we sometimes not only don’t want to know God but instead dare to deny his existence, but we who, by the grace of God, have the faith, when we find ourselves in the presence of such beautiful souls, surely nourished by faith, we cannot but discover in them an obvious sign of the existence of God, because one cannot have such a goodness without the grace of God.
Blessed Pier Giorgio Frassati (1901–1925)
