The mystery of vocation

Jesus went up the mountain and summoned those whom he wanted  and they came to him. He appointed twelve (whom he also named apostles) that they might be with him and he might send them forth to preach and to have authority to drive out demons: (he appointed the twelve:) Simon, whom he named Peter; James, son of Zebedee, and John the brother of James, whom he named Boanerges, that is, sons of thunder; Andrew, Philip, Bartholomew, Matthew, Thomas, James the son of Alphaeus; Thaddeus, Simon the Cananean, and Judas Iscariot who betrayed him. (Mark 3:13-19).

I'm going to be doing only one thing: I shall begin to sing what I must sing eternally: "The Mercies of the Lord!» (Ps 89[88],1)... Opening the Holy Gospels my eyes fell upon these words: "And going up a mountain, he called to him men of his own choosing, and they came to him." This is the mystery of my vocation, my whole life, and especially the mystery of the privileges Jesus showered upon my soul. He does not call those who are worthy but those whom he pleases or as St. Paul says: "God will have mercy on whom he will have mercy, and he will show pity to whom he will show pity. So then, there is question not of him who wills nor of him who runs, but of God showing mercy" (Rm 9: 15-16).

I wondered for a long time why God has preferences, why all souls don't receive an equal amount of graces. I was surprised when I saw him shower his extraordinary favors on saints who had offended him, for instance, St. Paul and St. Augustine, and whom he forced, so to speak, to accept his graces. When reading the lives of the saints, I was puzzled at seeing how Our Lord was pleased to caress certain ones from the cradle to the grave, allowing no obstacle in their way... 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... And so it is in the world of souls. 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. (St Therese of Child Jesus)
