Macrina Wiederkehr writes in “A Tree Full of Angels”:

Fasting makes me vulnerable and reminds me of my frailty. It reminds me to remember that if I am not fed I will die … Standing before God hungry, I suddenly know who I am. I am one who is poor, called to be rich in a way that the world does not understand. I am one who is empty, called to be filled with the fullness of God. I am one who is hungry, called to taste all the goodness that can be mine in Christ.
