Obviously, my daughters and sons, there are certain limits to our behaviour, because we are children of God; while at the same time we feel, and really are, free. The barriers on motorways, which prevent cars from going off the road, seem like a denial of freedom only to someone who does not really want to go where the motorway is going. Only a person with no common sense would want to get rid of all limitations on the road. If a car driver said, "What are these barriers for?" and drove through them onto the other side of the motorway, he would be no freer for doing so, and what is more he would destory other people's freedom, while ending up killing himself.
- St. Josemaria Escriva
