I wondered for a long time why God has preferences, why all souls don’t receive an equal amount of graces…
Jesus deigned to teach me this mystery. He set before me the book of nature; I understood how all the flowers He has created are beautiful, how the splendor of the rose and the whiteness of the Lily do not take away the perfume of the little violet or the delightful simplicity of the daisy. I understood that if all flowers wanted to be roses, nature would lose her springtime beauty, and the fields would no longer be decked out with little wild flowers.
And so it is in the world of souls, Jesus’ garden. He willed to create great souls comparable to Lilies and roses, but He has created smaller ones and these must be content to be daisies or violets destined to give joy to God’s glances when He looks down at his feet. Perfection consists in doing His will, in being what he wills us to be.
I understood, too, that Our Lord’s love is revealed as perfectly in the most simple soul who resists His grace in nothing as in the most excellent soul; in fact, since the nature of love is to humble oneself, if all souls resembled those of the holy Doctors who illumined the Church with clarity of their teachings, it seems God would not descend so low when coming to their heart. But He created the child who knows only how to make his feeble cries heard; He has created the poor savage who has nothing but the natural law to guide him. It is to their hearts that God deigns to lower Himself. These are the wild flowers whose simplicity attracts Him. When coming down in this way, God manifests His infinite grandeur. Just as the sun shines simultaneously on the tall cedars and on each little flower as though it were alone on the earth, so Our Lord is occupied particularly with each soul as though there were no others like it. And just as in nature all the seasons are arranged in such a way as to make the humblest daisy bloom on a set day, in the same way, everything works out for the good of each soul.
