Not my words, but Killian Noe’s:
If we are to grow up spiritually, if we are to become who we were created to become, we need structures in our lives in which we are held accountable to that becoming. We need people in our lives who will hold us to the commitments that keep us in the process of growing spiritually. Again, spiritual practices like prayer, sharing of resources and being with the suffering and excluded have no power in themselves to heal and transform. These practices merely keep us in the process of growing up spiritually. Spiritual practices are what keep the doors of our hearts open to the power of the Spirit of God. That Spirit does the healing and transforming.
I don’t know that much else needs to be added to that.
