As John Paul II aged so publicly, with Parkinson’s and much other wear and tear taking their very obvious tolls, he continued to proclaim the Gospel with remarkable vigor.
Just two and a half years before he died, he gave us a hint as to how this was possible …
The indispensable source of energy and renewal, when frailty and weakness increase, is the encounter with the living Christ, Lord of the covenant. This is why you must develop an intense spiritual life and open your soul to the word of life.
– John Paul II, from an address to the Plenary Assembly of the Pontifical Council for the Family, October 18, 2002
