Perfection... from St. Faustina's Diary

"When I had gone to the chapel for a moment, the Lord gave me to know that, among His chosen ones, there are some who are especially chosen, and whom He calls to a higher form of holiness, to an exceptional union with Him. These are seraphic souls, from whom God demands greater love than He does the others.  Although all live in the same convent,  yet He sometimes demands a particular soul a greater degree of love.  Such a soul understands this call, because God makes this known to it interiorly, but the soul may either follow this call or not. It depends on the soul itself whether it is faithful to these touches of the Holy Spirit, or whether it resists them. I have learned that there is a place in purgatory where souls will pay their debt to God for such transgressions; this kind of torment is the most difficult of all. The soul which is specially marked by God will be distinguished everywhere, whether in heaven or in purgatory or hell. In heaven, it will be distinguished from other souls by greater glory and radiance and deeper knowledge of God. In purgatory, by greater pain, because it knows God more profoundly and desires Him more vehemently. In hell, it will suffer more profoundly than other souls, because it knows more fully whom it has lost. This indelible mark of God's exclusive love, in the [soul], will not be obliterated." - Divine Mercy In My Soul, Notebook V #1556 

"Let the souls who are striving for perfection particularly adore My mercy, because the abundance of graces which I grant them flows from My mercy. I desire that these souls distinguish themselves by boundless trust in My mercy. I myself will attend to the sanctification of such souls. I will provide them with everything they will need to attain sanctity. The graces of My mercy are drawn by the means of one vessel only, and that is -- trust.  The more a soul trusts, the more it will receive. Souls that trust boundlessly are a great comfort to Me, because I pour all the treasures of My graces into them. I rejoice that they ask for much, because it is my desire to give much, very much. On the other hand, I am sad when souls ask for little, when they narrow their hearts." - Jesus to St. Faustina, Divine Mercy In My Soul, Notebook V #1578
