Jesus said “ paint a picture according to the vision you see and with the signature, Jesus, I trust in You, I desire that this picture be venerated first in your chapel and then throughout the whole world”. Later Sr. Faustina’s Spiritual Director told her to ask Jesus what the rays signified and Jesus explained to her -

“The rays represent the Blood and Water which gushed forth from the depths of my Mercy when My agonising Heart was pierced on the cross. The pale rays symbolise the water, which cleanses and purifies the soul: the red rays represent the blood, which gives new life to the soul. These rays will shield the soul before the justice of My Father. Fortunate are those who live in this shelter, for the justice of God will not reach them there”.

St. Faustina writes in her diary: “The Lord permitted me to see the immensity and greatness of His Mercy. If souls could only realise how much God loves them! Earthly human understanding, is only a pale shadow of the reality,” Jesus pleaded for help in seeking the return, through His mercy, of all who have lost their faith and offended God.

Write, the greater the sinner, the greater the mercy. Summon all those to confidence in the incomprehensible depth of My Mercy for I desire to save all. The well of Mercy was opened wide with a lance on the Cross, for all souls. I do not exclude anyone.”

Again and again, Our Lord visited Sister Faustina and repeated His appeal to sinners calling them to His open arms. “Know, my daughter, that My Heart is Mercy itself. From this sea of mercy graces pour out upon the whole world. No souls that come to Me depart without being comforted. All misery vanishes in My Mercy: and every grace, redemptive and sanctifying, stems from this source”.

On another occasion, Jesus complained of our lack of trust in Him “Distrust tears at My Heart. The lack of confidence in chosen souls hurts me most. Despite my inexhaustible love, they do not trust me.

Tell ailing mankind to draw close to My Merciful Heart and I will fill them with peace. Mankind will not find solace until it turns with confidence to My Mercy and love.”
