Pope John Paul II shared these thoughts on Divine Mercy in 2001:
"Today the Lord also shows us His glorious wounds and His heart, an inexhaustible source of light and truth, of love and forgiveness.... St. Faustina saw coming from this Heart that was overflowing with generous love, two rays of light which illuminated the world. 'The two rays,' according to what Jesus Himself told her, 'represent the blood and the water' (Diary, 299). The blood recalls the sacrifice of Golgotha and the mystery of the Eucharist; the water, according to the rich symbolism of the Evangelist St. John, makes us think of Baptism and the Gift of the Holy Spirit (cf. Jn 3:5; 4:14). "Through the mystery of this wounded heart, the restorative tide of God's merciful love continues to spread over the men and women of our time. Here alone can those who long true and lasting happiness its secret."
