Don Bosco's Advice To Teenagers
"Look, you will soon face a dangerous crisis; the devil will try to ensnare you. To start with, he will tell you that frequent Communion is good for children, not for adults, and that once in a great while is quite enough for you. Then he will do his best to keep you from sermons by making you feel bored by God’s words. He will convince you that certain things are not sinful. Then you’ll have to tussle with friends and what they might say, with [dangerous] readings, with your own passions, and so on. Be on your guard. Do not let the devil rob you of that piece of mind and purity of soul which makes you God’s friends!"
—St. John Bosco
