Saint John Paul II: "Be prepared to undergo great trials"

The following comes from In God's Company 2:

St. John Paul II in that candid interview with pilgrims in Germany:
November 1980

We must be prepared to undergo great trials in the not-too-distant future; trials that will require us to be ready to give up even our lives, and a total gift of self to Christ and for Christ. Through your prayers and mine, it is possible to alleviate this tribulation, but it is no longer possible to avert it, because it is only in this way that the Church can be effectively renewed. How many times, indeed, has the renewal of the Church been effected in blood? This time, again, it will not be otherwise. We must be strong, we must prepare ourselves, we must entrust ourselves to Christ and to His Mother, and we must be attentive, very attentive, to the prayer of the Rosary. —POPE JOHN PAUL II
