[T]he power that changes the world and transforms it into the Kingdom of God, in silence and without fanfare, is faith - and prayer is the expression of faith. When faith is filled with love for God, recognized as a good and just Father, prayer becomes persevering, insistent, it becomes a groan of the spirit, a cry of the soul that penetrates God's Heart. Thus, prayer becomes the greatest transforming power in the world. In the face of a difficult and complex social reality, as yours certainly is, it is essential to strengthen hope which is based on faith and expressed in unflagging prayer.
