1. Because you think you’re strong, but your enemies are stronger than you.
Alone you can not defeat the world, which without ceasing, assaults you with promises of glory that always end in nothing, nor can you defend yourself from the devil who puts thousands of lies in your head, thus sowing in your soul distrust towards the goodness of God. Think about your own flesh; it drags you down with its passions and makes you follow all its whims and desires. Against these powerful enemies there is only one solution. Just as the dove flies quickly to make its nest in the deep crevice of the rock to be safe from the talons of the eagle, so you must fly and make your nest in the profound depths of the Heart of Christ.
2. Because Jesus needs you to console him.
“Behold this Heart which has so loved men, that it has spared nothing, even to exhausting and consuming itself in order to testify to its love. In return, I have received from the greater part only ingratitude, by their irreverence and their sacrilege, and by the coldness and contempt they have for Me in this sacrament of Love.”
These were the words of Jesus to St. Margaret Mary. What a pity, don’t you think? How Jesus suffers for all sins in the world, especially for those against his Sacred Body in the Eucharist! If you do not console him, then who will?
3. Because "Who would not pay back with love, to He who has loved us so much?"
Jesus loved you so much that he has not saved himself any suffering in order to redeem you. It would be ungrateful if you did not try to correspond in some way to his love. It is not just a question of love but of justice. If you do not yet understand this, then you should contemplate the Heart of Jesus, fill yourself with Him, who is everything for you. Then go for it— leave behind all calculations and selfishness, and return "love for love."
