Habitual drunkenness is not one of those sins which time and grace will correct. To cure this sin, not an ordinary grace but a miracle of grace is required. You ask me why drunken people are so rarely converted. This is the reason: it is that they have neither faith, nor religion, nor pity, nor respect for holy things. Nothing is able to touch them or to open their eyes to their unhappy state.
