"My patrons in Heaven and my chosen favorites are those who have stolen it - like the Holy Innocents and the Good Thief. The great Saints have earned it by their works; as for me, I will imitate the thieves, I will have it by ruse, a ruse of Love which will open its gates to me and to poor sinners. The Holy Ghost encourages me, saying in the Book of Proverbs: O little one, come, learn subtilty of Me. (Prov. 1:4)"
~St. Thérèse of the Child Jesus and the Holy Face, from Counsels and Reminiscences

When we consider the divine world that envelops us already here in our exile and in which we can move, oh, then things here below disappear;  all of that doesn’t exist, it is less than nothing.  The saints, for their part, understood true knowledge so well, the knowledge that makes us leave everything, and especially ourselves, so we can fly to God and live solely with Him!
Blessed Elizabeth of the Trinity from Letter 184

It does us much good to look into the soul of saints and then to follow them through faith right up to Heaven; there, they are all luminous with the light of God, whom they contemplate face to face for all eternity!… The Heaven of the saints is our homeland. It is the Father’s House where we are awaited, where we are loved, where one day we, too will be able to fly and rest in the bosom of Infinite Love!  
~Bl. Elizabeth of the Trinity, Letter 184
