Jesus once lamented to St. Faustina how so many people don't seem to understand the Sacrament of Holy Communion and His Real Presence in the Eucharist.
"When I come to a human heart in Holy Communion," He said, "My hands are full of all kinds of graces which I want to give to the soul. But souls do not even pay attention to Me; they leave Me to Myself and busy themselves with other things. ... They treat Me as a dead object"
(Diary of St. Faustina, 1385)
