St. Faustina
“The Lord said to me, ‘Oh, how painful it is to Me that souls so seldom unite themselves to Me in Holy Communion. I wait for souls and they are indifferent toward Me. I love them tenderly and sincerely, and they distrust Me. I want to lavish My graces on them, and they do not want to accept them. They treat me as a dead object, whereas My Heart is full of love and mercy. In order that you may know at least some of My pain, imagine the most tender of mothers who has a great love for her children, while those children spurn her love. Consider her pain. No one is in a position to console her. This is but a feeble image and likeness of My love.'”
