St. Margaret Mary
“Behold this Heart which has so loved men that it has spared nothing, even to exhausting and consuming itself, in order to testify its love. In return, I receive from the greater part only ingratitude, by their irreverence and sacrileges, and by the coldness and contempt they have for me in this sacrament of love…. I come into the heart I have given you in order that through your fervor you may atone for the offenses which I have received from lukewarm and slothful hearts that dishonor me in the Blessed Sacrament”.
