The Divine Mercy devotion:

“The Divine Mercy” is a powerful rendering by Saint Faustina Kowalska, a Polish nun. It is recorded within the Roman Catholic sacred circles that Jesus communicated to the world through this chosen nun, His message of God's mercy.

Saint Kowalska wrote, “In the evening, I saw the Lord Jesus clothed in a white garment. One hand raised in the gesture of blessing, the other was touching the garment at the breast. From beneath the garment, slightly drawn aside, there were emanating two large rays, one red, and the other pale. In silence I kept my gaze fixed on the Lord; my soul was struck with awe, but also with great joy. After a while, Jesus said to me: ‘Paint an image according to what you see.’”
