The Heart of Spirituality

I am reading "Called to Question" by Sr. Joan Chittister for a writing project I am working on. I came across this quote today that struck me and I thought I would share it with you:

We must not, if we are to be spiritual people, fail to realize that life is meant to be nothing but a growing ground in God. If we fail to cultivate that part of us that is our truest self, how can the self come to full life in us? The spiritual life is the discovery of the self God meant us to be so that who we are can be God's gift to the rest of the world.
