Faith thus illuminates the mystery of death and brings serenity to old age, now no longer considered and lived passively as the expectation of a calamity but rather as a promise-filled approach to the goal of full maturity. These are years to be lived with a sense of trusting abandonment into the hands of God,
our provident and merciful Father.
- St. Pope John Paul II
